Exchange Alley was in a fever of excitement. The Company's stock, which had been at a hundred and thirty the previous day, gradually rose to three hundred, and continued to rise with the most astonishing rapidity during the whole time that the bill in its several stages was under discussion. Mr. Walpole was almost the only statesman in the House who spoke out boldly against it. He warned them, in eloquent and solemn language, of the evils that would ensue. It countenanced, he said, "the dangerous practice of stockjobbing, and would divert the genius of the nation from trade and industry. It would hold out a dangerous lure to decoy the unwary to their ruin, by making them part with the earnings of their labour for a prospect of imaginary wealth." The great principle of the project was an evil of first-rate magnitude; it was to raise artificially the value of the stock, by exciting and keeping up a general infatuation, and by promising dividends out of funds which could never be adequate to the purpose. In a prophetic spirit he added, that if the plan succeeded, the directors would become masters of the government, form a new and absolute aristocracy in the kingdom, and control the resolutions of the legislature. If it failed, which he was convinced it would, the result would bring general discontent and ruin upon the country. Such would be the delusion, that when the evil day came, as come it would, the people would start up, as from a dream, and ask themselves if these things could have been true. All his eloquence was in vain. He was looked upon as a false prophet, or compared to the hoarse raven, croaking omens of evil. His friends, however, compared him to Cassandra, predicting evils which would only be believed when they came home to men's hearths, and stared them in the face at their own boards. Although, in former times, the House had listened with the utmost attention to every word that fell from his lips, the benches became deserted when it was known that he would speak on the South Sea question.The bill was two months in its progress through the House of Commons. During this time every exertion was made by the directors and their friends, and more especially by the Chairman, the noted Sir John Blunt, to raise the price of the stock. The most extravagant rumours were in circulation. Treaties between England and Spain were spoken of, whereby the latter was to grant a free trade to all her colonies; and the rich produce of the mines of Potosi-la-Paz was to be brought to England until silver should become almost as plentiful as iron. For cotton and woollen goods, with which we could supply them in abundance, the dwellers in Mexico were to empty their golden mines. The company of merchants trading to the South Seas would be the richest the world ever saw, and every hundred pounds invested in it would produce hundreds per annum to the stockholder. At last the stock was raised by these means to near four hundred; but, after fluctuating a good deal, settled at three hundred and thirty, at which price it remained when the bill passed the Commons by a majority of 172 against 55.…It seemed at that time as if the whole nation had turned stockjobbers. Exchange Alley was every day blocked up by crowds, and Cornhill was impassable for the number of carriages. Everybody came to purchase stock. "Every fool aspired to be a knave." In the words of a ballad, published at the time, and sung about the streets, "A South Sea Ballad; or, Merry Remarks upon Exchange Alley Bubbles. To a new tune, called 'The Grand Elixir; or, the Philosopher's Stone Discovered.'"

This is way out of my field, but you'd think that in a time of SPACs, billion dollar unicorns that lose money on every transaction but hope to make it up in volume, meme stocks, insane volatility, investor cults of personality and P/Es over a thousand, putting aside concerns might be a bad idea.
From Bloomberg:
Bill Hwang, a former hedge fund manager who’d pleaded guilty to insider trading, was deemed such a risk by Goldman Sachs Group Inc. that as recently as late 2018 the firm refused to do business with him.
Those misgivings didn’t last.
Wall Street’s premier investment bank, lured by the tens of millions of dollars a year in commissions that a whale like Hwang paid to rival dealers, removed his name from its blacklist and allowed him to become a major client. Just as Morgan Stanley, Credit Suisse Group AG and others did, Goldman fueled a pipeline of billions of dollars in credit for Hwang to make highly leveraged bets on stocks such as Chinese tech giant Baidu Inc. and media conglomerate ViacomCBS Inc.
Now Hwang is at the center of one of the greatest margin calls of all time, his giant portfolio in a messy and painful liquidation, and Goldman’s reversal has thrust it right into the mayhem.

AstraZeneca dust-up
This is Joseph
Statement from AstraZeneca was titled (emphasis mine):
AZD1222 US Phase III trial met primary efficacy endpoint in preventing COVID-19 at interim analysis
Gave results of:
79% vaccine efficacy at preventing symptomatic COVID-19
100% efficacy against severe or critical disease and hospitalisation
Comparable efficacy result across ethnicity and age, with 80% efficacy in participants aged 65 years and over
Statement from NIAID:
Late Monday, the Data and Safety Monitoring Board (DSMB) notified NIAID, BARDA, and AstraZeneca that it was concerned by information released by AstraZeneca on initial data from its COVID-19 vaccine clinical trial. The DSMB expressed concern that AstraZeneca may have included outdated information from that trial, which may have provided an incomplete view of the efficacy data. We urge the company to work with the DSMB to review the efficacy data and ensure the most accurate, up-to-date efficacy data be made public as quickly as possible.
Full results from AstraZeneca:
76% vaccine efficacy against symptomatic COVID-19
100% efficacy against severe or critical disease and hospitalisation
85% efficacy against symptomatic COVID-19 in participants aged 65 years and over
So a few points. One, the data was from the interim analysis, even though it was definitely out of date at the time of publication. Still, it was one of two reportable numbers. Noah Haber discusses this here, including noting that the protocol is publicly available.
Two, the media framing looks terrible. Unless the results are misreported, the interim analysis was 3% high in the overall and 5% low in the over 65 participants. These are small changes and kind of average out, given that efficacy in over 65 year old participants was a concern because of under-participation in the earlier AstraZeneca trials. But this framing seems excessive:
Federal officials were taken aback by the board’s allegations. One said the way that AstraZeneca handled the results was the equivalent of “telling your mother you got an A in a course, when you got an A in the first quiz but a C in the overall course.” Another said the disclosure by the board would inevitably hurt the company’s credibility with U.S. regulators.
I am not sure I would consider the two reports materially different. Certainly, I do not see them as being the difference between an A and C (probably I would call them both B's, compared to other trials and the degree of change between them). Since they were doing frequentist statistics, looking at numbers between the two prespecified analyses seems like a bad plan (p-hacking concerns arise). That said, why is the analysis plan not Bayesian?
That said, unless these numbers are false in some way, how is this a major change?
Finally, why doesn't the United States just give up on approving AstraZeneca and agree to allow it to be exported. It is pretty clear that US regulators have decided that they aren't interested in the product but the export restriction is blocking shipping it to other places that could actually use it. Why not be honest, say they won't need it (they don't) and allow it to be exported to other places across the globe who are desperate for vaccines. Isn't it in everybody's best interests to reduce variants by increasing resistance to covid-19 infections globally?
How is this the best plan?

Repost: I wonder where Republicans got the idea that they could get away with using false claims about election fraud to justify voter suppression
TUESDAY, MAY 3, 2016
Context only counts if it shows up in the first two dozen paragraphs
In the third paragraph, we have two conflicting claims that go to the foundation of the whole debate. If election fraud is a significant problem, you can make a case for voter ID laws. If not, it's difficult to see this as anything other than voter suppression. This paragraph pretty much demands some additional information to help the reader weigh the claims and the article provides it...
Stricter Rules for Voter IDs Reshape Races
By MICHAEL WINES and MANNY FERNANDEZ MAY 1, 2016
SAN ANTONIO — In a state where everything is big, the 23rd Congressional District that hugs the border with Mexico is a monster: eight and a half hours by car across a stretch of land bigger than any state east of the Mississippi. In 2014, Representative Pete Gallego logged more than 70,000 miles there in his white Chevy Tahoe, campaigning for re-election to the House — and lost by a bare 2,422 votes.
So in his bid this year to retake the seat, Mr. Gallego, a Democrat, has made a crucial adjustment to his strategy. “We’re asking people if they have a driver’s license,” he said. “We’re having those basic conversations about IDs at the front end, right at our first meeting with voters.”
Since their inception a decade ago, voter identification laws have been the focus of fierce political and social debate. Proponents, largely Republican, argue that the regulations are essential tools to combat election fraud, while critics contend that they are mainly intended to suppress turnout of Democratic-leaning constituencies like minorities and students.
More than twenty paragraphs later.
Mr. Abbott, perhaps the law’s most ardent backer, has said that voter fraud “abounds” in Texas. A review of some 120 fraud charges in Texas between 2000 and 2015, about eight cases a year, turned up instances of buying votes and setting up fake residences to vote. Critics of the law note that no more than three or four infractions would have been prevented by the voter ID law.
Nationally, fraud that could be stopped by IDs is almost nonexistent, said Lorraine C. Minnite, author of the 2010 book “The Myth of Voter Fraud.” To sway an election, she said, it would require persuading perhaps thousands of people to commit felonies by misrepresenting themselves — and do it undetected.
“It’s ludicrous,” she said. “It’s not an effective way to try to corrupt an election.”
I shouldn't have to say this but, if a story contains claims that the reporter has reason to believe are false or misleading, he or she has an obligation to address the issue promptly. Putting the relevant information above the fold is likely to anger the people who made the false statements, but doing anything else is a disservice to the readers.

E.W. Niedermeyer points out an important paradox with autonomous systems -- if Tesla's FSD didn't suck so much, it would be dangerous
The last four seconds of this vid show an egregious and utterly terrifying error for a system that calls itself “Full Self-Driving” https://t.co/B5wJV3dMrU

Here's the entire video.
Road and Track has a painful play-by-play.
But E.W. Niedermeyer explains how a pretty good autonomous driving system would actually be more dangerous.
The fact that "Full Self-Driving" is so laughably bad is actually the main reason we haven't had crashes yet. If it improves to the point where it only makes a potentially fatal screwup every 100 miles or more, that's when people will become inattentive and over-trusting. https://t.co/dxh43iI0jX

Regardless of where it's reported, this is big news (and potentially grounds for one hell of a class action lawsuit). Still, it's worth noting that highly skeptical coverage of Tesla and Musk is no longer limited to a few voices in the wilderness like Lopez of Business Insider and Hiltzik and Mitchell of the LA Times.
Tesla recently told California regulators that the "Full Self-Driving" beta software it's testing with select customers doesn't make them autonomous — nor will it any time soon.
Why it matters: The company is charging $10,000 extra for the not-really-self-driving, might-arrive-someday addition to its standard Autopilot adaptive cruise-control and lane-keeping feature.
- Meanwhile, CEO Elon Musk is selling investors on the notion that its full self-driving tech will enable Teslas to become money-generating robotaxis.
Our thought bubble: Tesla has one message for customers and investors, and another one for legal authorities.
Catch up quick: Legal transparency website PlainSite this week released a year's worth of correspondence between Tesla lawyers and the California Department of Motor Vehicles, which regulates autonomous vehicles.
- The agency had been pressing Tesla for details about the technology's evolving capability since late 2019 while reminding the company that it does not have a permit to deploy autonomous vehicles in California.

I love LA... Penultimate Snow
Last week and this past Monday, the weather included some late winter storms, very probably the last of the year. The snow line got down to twenty-five hundred feet. To put that in perspective, the highest point in the city of LA is just over five thousand feet and highest point in the county is just over over ten.
My standard joke about LA is that we have all the weather you could want; we just drive to it, so this weekend, I headed up the Angeles Crest not far from my place to catch the last snow of the season. Next year, when traveling won't feel so risky, I'll get a cabin and do some hiking. For now, though, these views will have to hold me.

Vaccine nuance
This is Joseph.
Are all covid-19 vaccines precisely equal? No. Should you care very much which one you get? Also no. This seems like a contradiction until we think it through.
Prior to the reporting of any phase 3 trials, the pre-specified efficacy for a useful vaccine was often cited as 50%. Here is an NPR story discussing this prior to Pfizer results. It is worth noting, as Bill Miller states, that even a weak vaccine likely reduces severity:
"That's certainly the case with the influenza vaccine," Miller adds. "People who get the vaccine may still get the flu, but, for the most part, their disease is milder than if they hadn't had the vaccine."
So how do the US vaccines stack up to this standard? For the trial endpoints, Pfizer is 95%, Moderna is 94%, and Johnson and Johnson is 72%. Even the lowest efficacy vaccine is almost exactly at the 75% Dr. Fauci pre-specified as what he was hoping for, even if he was unsure it was realistic. Further, there are other trade-offs between the vaccines, including price, storage requirements, or number of doses. The lower efficacy option has better storage properties, is cheaper and is only a single dose. The newer vaccines that might yet be approved also look good, AstraZeneca is 70% and Novavax is 89%, so there are a growing number of options far more effective than the pre-specified level needed for a useful vaccine.
Based on this, there are only safe and effective options available in the United States. I suppose that there might be some customer preferences, but everything is safe and works, based on the trial data.
So what can real world evidence add?
Well, we can try to find rare side effects. There was some concern about the AstraZeneca vaccine (not available in the US) and blood clots, at least until people noticed that the rate was lower than would be expected by chance. One of the sanest voices in the pandemic points out that this might be lower than by chance:
Professor Sir David Spiegelhalter, a statistician from the University of Cambridge, urged caution over the decision to pause the AstraZeneca vaccine rollout in some countries, saying it could be doing "more harm than good".
But it is important to monitor for problems. For example, if there were big ones with the Pfizer vaccine then you'd expect Israel to have noticed by now. Spoiler: there weren't any.
We can also measure the population level effects on disease. So we know that the AstraZeneca (AZ) vaccine appears to reduce population rates of hospitalization by 95%, which was higher than that seen post-vaccination by Pfizer, at 84% (this was based on 1.14 million vaccinations in Scotland) -- although this was mostly comparing single dose Pfizer to single dose AZ (results could differ after 2 doses). Both vaccines are mitigating the human cost of the pandemic, which is the reason the pandemic was a crisis to begin with.
So how does this all link together? All of the evidence suggests all of the vaccines are good. Scotland's real world evidence muddies the waters as to the precise rank ordering (as it is unlikely that the populations being vaccinated were terribly different) but that doesn't change the underlying message: none of the vaccines is showing concerns as to safety or efficacy. I would gladly be randomized to any of the three US available options or to AZ. Even if it was done with a biased die.
Finally, if I did have to do any sort of prioritization then I would do it via focusing on high risk populations. Give the mRNA vaccines to older and minority groups, who suffer more from the disease. Focus the adenovirus vaccines on the young and high SES crowd. That said, vaccines in arms is the most important variable and every person vaccinated does make the community, as a whole, safer.
Looking at Mar 15 data, you would rather be the US (21% with 1+ dose), Israel (57% with 1+ dose), or the UK (37% with 1+ dose) and not somebody like Canada (4.7% with 1+ dose). And the number of doses given is vastly more important than the type of vaccine used, provided it is one of the five above with extensively reported phase three clinical trial data.

If David Wallace-Wells was all that concerned about vaccine hesitancy, maybe he shouldn't have promoted the myth of a West Hollywood autism epidemic
What If Herd Immunity Is Out of Reach? [emphasis added]
A few months ago, these developments might have suggested the true endgame of the pandemic was in sight—and indeed the likely vaccination of 100 million or more by late spring does suggest a dramatic change in the country’s experience of the disease, with those vaccinated feeling safe from hospitalization and death and the disease in retreat. But thanks to a combination of higher herd-immunity estimates, stubbornly high vaccine “hesitancy,” and the arrival of new coronavirus variants that render existing vaccines less effective, the second year of the American pandemic is beginning to look less like a page-turning, book-slammed-shut bang and more like a long and indefinite whimpering into the future — in which many are protected but the disease, undefeated, still circulates, perhaps forever. That the coronavirus would become endemic, like the common cold, has always been one possible outcome, though less appealing than true elimination. The arrival of new variants has made that kind of near-term future, with enduring reservoirs of virus throughout the country, seem less appealing still.

David Wallace-Wells, autism and bad science
David Wallace-Wells has been catching a lot of flack (most of it richly deserved) for his recent New York Magazine article on climate change. It is a hugely troubling sign when the very scientists you were claiming to represent push back against your article.This controversy illustrates a larger problem with science reporting at the magazine. We already have a post in the queue discussing the neutral-to-credulous coverage of topics ranging from homeopathy to magic crystals to Gwyneth Paltrow's goop empire. The Wallace-Wells piece takes things to another level and goes in a very different but arguably worse direction. Rather than giving bad science a pass, he takes good science and presents it so ineptly has to do it a disservice.
I am not going to delve into that science myself. The topic has been well covered by numerous expert and knowledgeable writers [see here and here]. The best I could offer would be a recap. There are some journalistic points I may hit later and I do want to highlight a minor detail in the article that has slipped past most critics, but which is perfectly representative of the dangerous way Wallace-Wells combines sensationalism with a weak grasp of science.
Other stuff in the hotter air is even scarier, with small increases in pollution capable of shortening life spans by ten years. The warmer the planet gets, the more ozone forms, and by mid-century, Americans will likely suffer a 70 percent increase in unhealthy ozone smog, the National Center for Atmospheric Research has projected. By 2090, as many as 2 billion people globally will be breathing air above the WHO “safe” level; one paper last month showed that, among other effects, a pregnant mother’s exposure to ozone raises the child’s risk of autism (as much as tenfold, combined with other environmental factors). Which does make you think again about the autism epidemic in West Hollywood.
No, David, no it doesn't.
I want to be painstakingly careful at this point. These are complex and extraordinarily important issues and it is essential that we do not lose sight of certain basic facts: by any reasonable standard, man-made climate change is one of the two or three most important issues facing our country; the effect of various pollutants on children's mental and physical development should be a major concern for all of us; high ozone levels are a really bad thing.
But the suggestion that ozone levels are causing an autism epidemic in West Hollywood is both dangerous and scientifically illiterate. You'll notice that I did not say that suggesting ozone levels cause autism is irresponsible. Though the study in question is outside of my field, the hypothesis seems reasonable and I do not see any red flags associated with the research. If Wallace-Wells had stopped before adding that last sentence, he would've been on solid ground, but he didn't.
Autism is frightening, mysterious, tragic. This has caused people, particularly parents facing one of the worst moments imaginable, to clean desperately to any explanation that might make sense of their situation. As a result, autism has become a focal point for bad science, culminating with the rise of the anti-vaccination movement. There is no field where groundless speculation and fear-mongering are less welcome.
So, if ozone and other pollutants may contribute to autism, what's so bad about the West Hollywood claim? For that, you need to do some rudimentary causal reasoning, starting with a quick look at ozone pollution in Southern California.
Here are some pertinent facts from a 2015 LA Times article:
EPA Administrator Gina McCarthy selected a limit of 70 parts per billion, which is more stringent than the 75 parts-per-billion standard adopted in 2008 but short of the 60-ppb endorsed by environmentalists and health advocacy groups including the American Lung Assn. The agency’s science advisors had recommended a limit lower than 70 -- and as low as 60.
...
About one-third of California residents live in communities with pollution that exceeds federal standards, according to estimates by the state Air Resources Board.
Air quality is worst in inland valleys, where pollution from vehicles and factories cook in sunlight to form ozone, which is blown and trapped against the mountains.
The South Coast air basin, which includes Los Angeles, Orange, Riverside and San Bernardino counties, violated the current 75-ppb ozone standard on 92 days in 2014. The highest ozone levels in the nation are in San Bernardino County, which reported a 2012-2014 average of 102 parts per billion.
Now let's look at some ozone levels around the region. West Hollywood, it should be noted, is not great.
But just over the Hollywood Hills, the situation is even worse.
Higher still in Riverside ...
Though still far short of what we find in San Bernardino.
If you look at autism rates by school district and compare them to ozone levels, it is difficult to see much of a relationship. Does this mean that ozone does not contribute to autism? Absolutely not. What it shows is that, as with many developmental and learning disabilities, the wealthy are overdiagnosed while poor are underdiagnosed. It is no coincidence that a place like Santa Monica/Maibu (a notorious anti-vaxxer hotspot) has more than double the diagnosis rate of San Bernardino.
The there's this from the very LA Times article by Alan Zarembo that Wallace-Wells cites [emphasis added]:
Irva Hertz-Picciotto, an epidemiologist at UC Davis, suspects that environmental triggers such as exposure to chemicals during pregnancy play a role. In a 2009 study, she started with a tantalizing lead — several autism clusters, mostly in Southern California, that her team had identified from disability and birth records.
But the hot spots could not be linked to chemical plants, waste dumps or any other obvious environmental hazards. Instead, the cases were concentrated in places where parents were highly educated and had easy access to treatment.
Peter Bearman, a sociologist at Columbia University, has demonstrated how such social forces are driving autism rates.
Analyzing state data, he identified a 386-square-mile area centered in West Hollywood that consistently produced three times as many autism cases as would be expected from birth rates.
Affluence helped set the area apart. But delving deeper, Bearman detected a more surprising pattern that existed across the state: Rich or poor, children living near somebody with autism were more likely to have the diagnosis themselves.
Living within 250 meters boosted the chances by 42%, compared to living between 500 and 1,000 meters away.
The reason, his analysis suggested, was simple: People talk.
They talk about how to recognize autism, which doctors to see, how to navigate the bureaucracies to secure services. They talk more if they live next door or visit the same parks, or if their children go to the same preschool.
The influence of neighbors alone accounts for 16% of the growth of autism cases in the state developmental system between 2000 and 2005, Bearman estimated.
In other words, autism is not contagious, but the diagnosis is.

This is getting dumb
This is Joseph
Matt Yglesias commenting on the NYT:
Also noted by Alex Tabbarok:
AZ has on the order of 50 million doses nearly ready to go and can produce in the US around 25 million doses a month so over a year that production is worth over $100 billion to the world economy, far higher than the modest cost of production! Instead of idling this capacity we should expand it even further as part of a plan to vaccinate the world.
I think we need to have a very careful reality check. What could possibly be the reason for not allowing the export of the vaccine? People keep pointing out that Astra-Zeneca has not done the paperwork for an emergency use authorization, but what is the point of letting it sit unused when the company would like to export it.
If it works, why would the United States not want to use it? If it is inferior to current vaccines why should we deny it to countries dealing with large outbreaks? I understand not immediately authorizing it because the US has vaccines with good data already approved but then it should be exportable. I also understand wanting to use it domestically to speed up vaccination rates but then there should be hard questions asked about why the company is not applying to the FDA.
But the current course of action seems to make no actual sense. What am I missing? What is the value in letting the doses expire due to an export ban?

The sad part is this actually makes the first one look rational...
There was at least an initial logic to the first Gamestop bubble. If successfully executed, it is possible to make a great deal of money out of a short squeeze. This time, however, we are in pure delusional money territory.
“It’s a marathon, not a sprint. Whatever happens resist the urge to sell. The longer we hold the higher it goes,” said @catchme1fyoucan, an Italy-based user of retail trading platform eToro, in a discussion on GameStop.
For many, perhaps most, of the investors this time around, the lesson of the first bubble was exactly the wrong one. They believe they drove the stock up because of the rightness of their cause and the power of their will, and the only reason it went back down was a loss of faith.
The details of this surge don't do much to help clear things up for us non-believers.
One explanation was a tweet from activist investor Ryan Cohen, who is a major shareholder in GameStop and was appointed as a board member as part of an attempt to reverse the company’s ailing fortunes.
Mr Cohen is known as “Papa Cohen” on the Reddit forum, and is known to have a significant holding in the company. That means that his tweets have a particular pull for those who follow the stock – even if they might be largely incomprehensible to others.
One such tweet was posted by Mr Cohen on Wednesday evening. It showed a McDonald’s ice cream cone and was accompanied by a frog emoji.
Soon after that post, the shares began to surge. It is impossible to say definitively whether there is any connection between the stock price and Mr Cohen’s tweet, but it at least focused new attention on the GME shares.
In case you were wondering if the description leaves something out...
While we don't want to push the analogy too far, we live in a time of movements based on finding hidden messages in cryptic tweets. By the QAnon standard, buying Gamestop at $265 hardly seems crazy at all.
As I type this, it is snowing in the City of Los Angeles
At least in the parts above 2,500 feet. The highest point in the city is just over 5,000 feet so the snow line will cover a lot of square miles, even more in the eastern part of the county. The mountains will be beautiful.

With high flying stocks, most buy arguments are actually sell arguments
In the annals of investing literature, there are a few lessons which stick out. But perhaps none more so than the adage that at the right price, every asset is potentially a good investment. Even subprime CDOs. The flip side of this axiom is, of course, that if you pay too much the experience can be a painful one....At the turn of the new millennium, the IT hardware, software and networking equipment company was one of the hottest stocks in the US equity market. From the beginning of 1999 to March 2000 the shares rose 236 per cent to a market capitalisation of $555bn, or $80.06 per share, backed by a crazed-enthusiasm for the technological shifts bought about by the internet. The thesis was solid: as a provider of networking equipment for both telecom players and other businesses, Cisco was the shovel-seller in a dot com gold rush. What could go wrong?And, some might argue, it had the numbers to back it up. In the 2000 financial year, Cisco posted revenue growth of 55 per cent, gross margins of 66 per cent and had a return-on-equity of 14 per cent. Sure, top-line growth had slowed from 1994 when revenue had doubled, but as one of the few players sitting at the intersection of several technological trends, it surely was going to be one of the big winners of the new millennium.Well yes and no. In one way, investors were right. Cisco was a big winner. Over the next 21 years, Cisco’s revenues grew four fold to $49bn, with profits quintupling to $11bn. Return-on-equity even improved, with the figure averaging 17 per cent over the next two decades, 3 percentage points above its 2000 number.The problem was the share price. It was, simply, too damn high. At the March 2000 peak, Cisco’s price-to-earnings ratio stood at 201 times, its enterprise value to sales at 31 times and its price-to-free cash flow at 176 times. By anyone’s standards, the valuation was over-egged.And, suddenly, everyone cottoned on. Over the next two years, Cisco’s share price collapsed 80 per cent, a total market capitalisation loss of $431bn, as the dot com bubble deflated and telecom capital expenditure with it. Twenty-odd years later at pixel time, Cisco’s shares are at $46.25, still 42 per cent below their dot com peak.
Imagine a stock analyst in 2000 who sat down with Louis Rukeyser and laid out a scenario for Cisco that was completely prescient. The case would sound spectacularly bullish. The company really did have a long and profitable future ahead of it. In the context of Cisco's peak price, however, this would have been anything but a case for going all in. When a stock is flying that high, what would normally be a buy argument more often than not becomes a sell argument.
Alex Wilhelm writing for TechCrunch:
Using normal accounting rules, Uber lost $6.77 billion in 2020, an improvement from its 2019 loss of $8.51 billion. However, if you lean on Uber’s definition of adjusted EBITDA, its 2019 and 2020 losses fall to $2.73 billion and $2.53 billion, respectively.
Despite this, Uber has a market cap of over $100 billion. Its spokespeople and shills will argue that the company is about to become profitable but even if it does go into the real black (and not just the creative accounting black), no one is offering a convincing scenario where the stock is worth more than a fraction of its current price;
A lot of investors, particularly retail investors, operate under the assumption that if you like a company and have faith in it, you should buy. They ignore Powell's basic lesson that any investment is a bad investment beyond a certain price and, as he points out, sooner or later someone is in for a painful experience.

The self-proclaimed "next Warren Buffett" is perfect for the age of Trump and Musk
These are the kinds of charlatans who show up when Wall Street gets weird
King of wishful SPAC-ing
There are a few ways to tell if the person you are listening to is a bubble charlatan. For one thing, they can't handle criticism of themselves or their product. Debate — one of the most important elements of price discovery — is not tolerated. To them, short sellers are market villains. They also dislike traditional valuation metrics, regulators who put guardrails around trading or promoting, and — to ingratiate themselves with retail investors — other rich people.
You can also find them shilling free advice on social media and constantly calling into CNBC to rant.
Chamath Palihapitiya, founder of the now defunct venture-capital firm Social Capital, is skilled at all of those things. His success stems mainly from being at Facebook early. Since then he has perfected the art of raising money from people who should know better, and teasing a run for governor of California.
...
Did I mention that Palihapitiya hates short sellers?
About the time Lopez hit send on her piece, Palihapitiya's most hyped SPAC reached what we might call the post-pump stage.

A small point on Kevin Drum
No, it wouldn't turn us into a "papers please" police state. No, it wouldn't do anything that we haven't already done in a chaotic way already.
Like this case here of a passenger in a car being arrested for not showing ID at a traffic stop. Similarly, there are already stop and identify laws. I am not sure that a secure national id would do anything to make this situation worse and would be a nice way to get around issues like name conflicts in e-verify.
Just imagine what they could have done with blockchains -- a proto-SPAC repost
Michael Hiltzik writing for the LA Times:
Someone on Wall Street ought to erect a statue to Henry Villard.
Villard made the discovery that if you don’t tell investors how you’re going to spend their money, they get more eager, not less.
Seeking to raise several millions of dollars in capital to take over a company but unwilling to reveal his target for fear of driving its price beyond his reach, Villard sent out a prospectus for a “blind pool,” stating that he would reveal “the exact nature” of his plans 90 days hence.
Rather to his surprise, his pool was sold out within 24 hours; indeed, investors bid for twice what he was asking. “All wanted more,” he recalled.
The year was 1881. Villard’s quarry was the Northern Pacific Railroad, with which he hoped to build a railroad network to the Pacific Northwest.
But what makes his scheme relevant is that the same principle of raising money via a blank check has become the latest craze sweeping Wall Street....
All would be well-advised to consider the ultimate fate of Henry Villard. As he neared the apogee of success, he built a landmark residence on New York’s Madison Avenue, designed by Stanford White, that is still remembered as the Villard Houses.
One night after he moved in, he was visited by a delegation of investors and auditors who informed him he was bankrupt. He and his family vacated the residence, which was sold to Whitelaw Reid, publisher of the New York Tribune.
Much later it served as the facade of the 55-story Helmsley Palace Hotel, where the society figure Leona Helmsley reigned until her conviction for tax evasion in 1989. The hotel passed into the ownership of the Sultan of Brunei, who eventually sold it to a South Korean resort firm that operates it today.
Villard had one more brush with greatness. In 1887 he was invited to resume the presidency of the Northern Pacific but drove it into receivership by loading it with extortionate loans to himself.
But with all due respect to Villard, he was by no means the first.

"A company for carrying on an undertaking of great advantage, but nobody to know what it is."
Another excerpt from Charles Mackay's Extraordinary Popular Delusions and the Madness of Crowds. I believe "a company for carrying on an undertaking of great advantage, but nobody to know what it is" was an initial business plan for Groupon.Some of these schemes were plausible enough, and, had they been undertaken at a time when the public mind was unexcited, might have been pursued with advantage to all concerned. But they were established merely with the view of raising the shares in the market. The projectors took the first opportunity of a rise to sell out, and next morning the scheme was at an end. Maitland, in his History of London, gravely informs us, that one of the projects which received great encouragement, was for the establishment of a company "to make deal-boards out of saw-dust." This is, no doubt, intended as a joke; but there is abundance of evidence to show that dozens of schemes hardly a whir more reasonable, lived their little day, ruining hundreds ere they fell. One of them was for a wheel for perpetual motion—capital, one million; another was "for encouraging the breed of horses in England, and improving of glebe and church lands, and repairing and rebuilding parsonage and vicarage houses." Why the clergy, who were so mainly interested in the latter clause, should have taken so much interest in the first, is only to be explained on the supposition that the scheme was projected by a knot of the foxhunting parsons, once so common in England. The shares of this company were rapidly subscribed for. But the most absurd and preposterous of all, and which showed, more completely than any other, the utter madness of the people, was one, started by an unknown adventurer, entitled "company for carrying on an undertaking of great advantage, but nobody to know what it is." Were not the fact stated by scores of credible witnesses, it would be impossible to believe that any person could have been duped by such a project. The man of genius who essayed this bold and successful inroad upon public credulity, merely stated in his prospectus that the required capital was half a million, in five thousand shares of 100 pounds each, deposit 2 pounds per share. Each subscriber, paying his deposit, would be entitled to 100 pounds per annum per share. How this immense profit was to be obtained, he did not condescend to inform them at that time, but promised, that in a month full particulars should be duly announced, and a call made for the remaining 98 pounds of the subscription. Next morning, at nine o'clock, this great man opened an office in Cornhill. Crowds of people beset his door, and when he shut up at three o'clock, he found that no less than one thousand shares had been subscribed for, and the deposits paid. He was thus, in five hours, the winner of 2,000 pounds. He was philosopher enough to be contented with his venture, and set off the same evening for the Continent. He was never heard of again

He's gotta a great big house on the cliffside, 'nother great big house beside it
Back in '88, having side by side swimming pools seemed an absurd example of wretched excess. If only we'd known.
WhatsApp co-founder Jan Koum just grabbed another slice of Malibu shoreline, paying $87 million for an oceanfront home right next to his other one, The Times has confirmed.
The billionaire has been on a Southern California spending spree for the last three years. In 2019, he paid $100 million for the Malibu home of longtime NBCUniversal executive Ron Meyer. A year later he ventured inland, shelling out $125 million for the Beverly Hills mansion of Quibi founder Jeffrey Katzenberg.
The $87-million sale, which was first reported by the Wall Street Journal, is by far the priciest home sale in L.A. County so far this year. The property originally was put on the market last summer for $125 million, The Times previously reported.

Tesla, the Sinatra of car companies

So, the situation is that the Tesla’s owner was driving along the I-5 North in Los Angeles, with Autopilot engaged, when a truck changed lanes in front of the Tesla, to which the Tesla reacted by maintaining its speed and crossing over the unbroken white line that marks where the highway divides between the I-5 North and the 101 North, putting the car onto the 101 North instead of its intended path.The Tesla owner refers to the truck as “changing lanes last minute” and that the actions of the car “saved my life” and that Autopilot is “life saving tech.”My problem here is that any human driver would have seen that the truck had its turn indicator on, and was making a pretty normal lane change. You can see the turn indicator blinking from the very start of the dashcam clip; the truck was clearly intending to change lanes, and I don’t see how you’d call it “last minute” unless you just started paying attention as it began actually changing lanes.We’ve all been in this exact same situation, and we’ve all done the same thing: let off the gas a bit to slow down slightly, and let the truck change lanes in front of us. It’s trivial, really. For most drivers, you can’t even remember how many times you’ve done this.You just slow down a bit. Not a brake stomp, just a slight slowing to let the truck in. No biggie.Stubbornly maintaining the same speed and ignoring the truck that is clearly signaling a lane change until it actually begins to move into the lane, as Autopilot did, is just bad driving; plus, Autopilot put the car onto the wrong freeway for the driver’s destination, which she did note she corrected in another tweet:

Bitcoin thoughts
This is Joseph
Just a quick hit (thanks to Mark's cunning eyesight) to note that this Bitcoin report is hilariously bad, as noted by Jemima Kelly. The author of the Financial Times article notes that the authors mistake basis points for percentage points, which leads them to suggest 13.46% of credit and debit card activity is fraudulent. That would be . . . amazing if true.
They also claim that 36% of small and medium businesses will accept Bitcoin in the US. There are some caveats in this point by Thomas Lumley that the two things are not identical but the volume of Bitcoin, worldwide, is a lot lower than the credit and debit card volume of the New Zealand economy. That's not really a sign of it being a major player as a form of payment, even if a lot of places might (technically) be able to accept them.
This is besides the increasing issue with the power consumption issues with Bitcoin.
If nothing else, the value of Bitcoin is going to need to be a lot more stable to be a good currency. The current high level of volatility of Bitcoin is the opposite of what we want in a store of value for exchange purposes and the idea that it might spike in value (relative to the dollar) is exactly what makes it a bad currency when things like taxes are in dollars.

Out with the Wages of Strauss, in with the Great Unwinding
We have reached a point in the show which always makes the fans a little nervous. we have decided that one of our oldest and biggest storylines is starting to come to a natural conclusion so we need to begin wrapping up the loose ends and introducing the next one.
For years now, when it came to politics, the big recurring story was what you might call the wages of Strauss. we pushed the we pushed the idea that either the main cause or the essential context of almost every major political development over the past couple of decades came from the conservative movements relatively public conclusion that their agenda, while it might hold its own for a while and perhaps even surge ahead now and then, was destined to lose the battle of public opinion in the long run.
This left them with two choices, either modify their ideas so that they could win over the majority of the public, or undermine the Democratic process through a Straussian model, an approach based on controlling most of the money and increasing the influence that could be bought with that money, changing government so that an ever smaller part of the population had an ever-larger role in governing the country and creating a sophisticated three-tiered information management system where trusted sources of information were underfunded and undermined, the mainstream press was kept in line through a combination of message discipline and incentives with special emphasis placed on working the refs, and the creation of a special media bubble for the base which used spin, propaganda, and outright disinformation to keep the canon fodder angry, frightened, and loyal.
For a long time this approach worked remarkably well, but you could argue that the signs of instability were there from the beginning, particularly the difficulty of controlling the creation and flow of disinformation, the vulnerability to what you might call hostile take over, and the way the system lent itself to cults of personality.
We've had a good run with this storyline for a long time now, but it seems to be coming to a resolution and it has definitely lost a great deal of its novelty. (Lots of people are making these points now.)
The next big story, but one which we believe will dominate American politics for at least the next decade or so will be how the Republican party deals with the unwinding of the Trump cult of personality. Dismantling such a cult is tremendously difficult under the best of circumstances where the leader can be eased out gently, but you have with Donald Trump someone who has no loyalty to the party whatsoever and who is temperamentally not only capable but inclined to tear the house down should he feel betrayed.
If Trump continues to grow more erratic and public disapproval and support for his removal continues to grow, then association will be increasingly damaging to Republicans in office. However, for those same politicians, at least those who come up for election in the next two to four years, it is not at all clear that any could survive if the Trump loyalists turned on them.
But this goes beyond individual candidates. Trump's hold on the core of the base is so strong and so personal that, if he were to tell them directly that the GOP had betrayed both him and them, they would almost certainly side with him. They might form a third party, or simply boycott if you elections, or, yes, even consider voting for Democrats.. I know that last one sounds unlikely but it is within the realm of possibility if the intraparty civil war got bitter enough.
Obviously, if Trump survives this scandal and is reelected in 2020, all of this is moot, but if not, then how things break will be a story we’ll be glad to have been following.

More on the great unwinding -- the post-Trump GOP is probably inevitable but still unimaginable
Just to reiterate a few points we've been hammering for a few years now.
1. Trump has become more and more toxic to a growing majority of the
country. If things continue going the way they're headed, he will be the
ultimate example of von Hoffman's rat on the kitchen floor for the
Republican Party.
2. But unlike with Nixon, the base is personally loyal to Trump, not to the GOP.
No flight to Berchtesgaden for this loyal man—he's staying in the bunker https://t.co/jlZf09aIlA
— George Conway (@gtconway3d) October 6, 2020
3. It is difficult to describe what we're seeing as anything other than a cult of personality, complete with the Soviet style propaganda images, the assumption of mental and physical perfection and the messianic overtones.
4. Even if the base were to continue to support the party, the Republicans absolutely must broaden its appeal. After 1988, they have won the popular vote for the presidency exactly once and that was the special case of a wartime reelection.
5. But the base will not tolerate disloyalty to either Trump or his message. Keeping them happy while broadening support is impossible, but the alternative is to find a way to go from a minority to a majority party while trying to make up for the loss of around half of your supporters.
Are there scenarios where this does happen relatively quickly? Sure, but there are no obvious paths that don't require some deus ex machina plot twist. Which leads to the final and most important point.
6. With a handful of possible exceptions like the extraordinarily sharp Josh Marshall, observers are almost all underestimating the chances of profound and unexpected changes to the way American politics works. I'm not saying what's going to fall or which direction it will tip, but things are going to be different.
From Marshall
But don’t take your eyes off this broader calculus – one separate from Trump, his state of mind, one that is above all rational. Yes, everyone should give their 110%. Everybody get out to vote. The stakes for a second Trump term are too high to take anything for granted. But for those gaming out their own moves and post-January realities, Trump’s defeat is starting to look very likely. Under normal circumstances that would lead congressional Republicans to cut Trump loose and pitch their reelection as a check on the power of a Democratic President. That would be a great card to play for a number of endangered Republican Senators at the moment. But it’s all but impossible since loyalty to Trump is now the centerpiece of Republican identity. And any move away from him would trigger a fatal backlash.______________________________________________________
