I'd be very worried about Robin Hood's solvency, since they let people trade on margins, and retail investors are presumably difficult to get debts out from. I seriously doubt they underwrite their own options, more likely they just sell some broker's options.

Otherwise... sure some funds might lose a lot of money. But a lot of money for a fund (and it's investors). I wouldn't say we're seeing anything like systemic risk. If nothing else, Redditors' pockets are only so deep, and there's only so much meme stocks they can buy.

So where does it leave us? Perhaps Robin Hood might go under (though it looks like they learnt their lesson and got some cash, so maybe not). Some funds went under, and maybe some other will too. But generally, funds are not major systemic risk. They are speculative money. It's been going on for long enough that clearing houses requested the higher margins already. I don't think banks have any real skin in this game.

What was so terrible about 2008 financial crash, from the technocratic point of view, was that it was banks that were affected, and they are, among other things, the very plumbing of the financial system we all depend on.

Of course life can prove me wrong :) but I'm not remotely worried atm.
>The mainstream media is pure evil. They will go to any lengths to protect their billionaire owners and friends.

This assumes billionaires are some sort of cohesive group that's collectively hurting from the GME frenzy, when really there's plenty of billionaires that are making money off this. Citadel just got a bunch of ownership in Melvin for cheap for instance, and MUST asset management unloaded a bunch of stocks for a tidy profit.
So do everything up to specifically stating the effect that you want, and it’s not market manipulation? This is the “emperor’s new clothes” absurdity of this whole system.

> Given Apple's focus on privacy combined with their huge footprint in the US, Facebook may see them as an existential threat, and be using the word "competitor" to represent that.

I agree that Apple is an existential threat to Facebook, given that Apple has absolute control over software distribution on iPhone. In that sense they're competitors, but not in the standard sense of having competing products.
In a way, sure. The reality is they are mostly a consolidation play.

I don't think Nvidia was a particularly obvious play at the time. GPU bitcoin mining had taken off and GPUs were in high demand, but I don't think many people realised GPU compute would take off the way it did: everyone I knew in ML was still using clusters and most of them were using Matlab.

Even if you took it for granted that GPU-powered deep learning was the next big thing, it wasn't obvious that NVIDIA would be the dominant player. CUDA made GPGPU programming easy at the time, but any other manufacturer could have released something better. It just didn't play out that way.

Alexnet was 2012 by the way. Shortly after Nvidia stock tanked!

The map isn't supposed to be the terrain; Generating wealth isn't the same as generating money, and the stock market seems to exist almost entirely for the latter, at the cost of the former.

We're in a situation where playing in the market is a better strategy than using the market for its legacy purposes (you know, buying partial ownership in companies) and the number of financial tools created specifically to exploit the ability of wealth to generate additional wealth vastly out match everything else.

First and foremost, no company should benefit from this kind of lopsided non-arrangement to spy/ track me. I don't care if it's Facebook or Bob the window washer, they shouldn't be tracking me this way without permission.

Also, I don't agree that this is going to broadly affect small businesses. I accept that it's possible a few businesses in some places will be hit, but there isn't a ton of evidence that it's going to have a broad impact. Facebook still has massive profiles of users to provide a broad set of ad targeting tools.

Obviously you affiliate with Republicans (as did I until relatively recently). Why do you feel the need to defend someone who discredits your group by openly believing bonkers things?

To a nerd of a generalist science+engineering variety who occasionally short-sells individual stocks, this analysis feels heartening.

Consider:

> quants often rely on measures of valuation, volatility, or momentum to guide their process, based on the historical success of these metrics in predicting returns, and in nearly every case following the numbers led investors astray in 2020, starting with perhaps the most time-tested of financial strategies, value investing.

> When Google tweaks a caching algorithm to enable 10% more with the same hardware/energy input, that contributes to economic growth with less resources.

Sure, but that also increases Google's net profit and allows its users to make more queries. That profit is then maybe invested to penetrate new market segments like transportation or hardware production, or is distributed among CEOs who buy bigger houses and more cars.

In essence, the efficiency gains of improving the algorithm are lost because of the free-flowing streams of capital.

The reason we have inadequate evidence is the relatively low priority of SETI compared to other science.

SETI has literally been living off financial scraps for decades. If a couple of billionaires hadn't funded efforts with very generous personal donations there would be almost no SETI at all.

And if SETI had been funded properly - which would still be a drop in the ocean compared to other government spending, nationally and internationally - we'd have more observations to draw on from other sources.

This is all quite strange considering how much of a game changer and scientific motivator evidence of ETI would be.
> “lol idk sorry Dick but we’re just gonna let you go and let the Fed bail the rest of us out sorry bro lol.” Like really. That’s how it went behind those closed doors in the lairs of the lizards that control the universe.

Says Dick Fuld. I doubt that's true, though, because at the time Lehman was going under, they didn't know that all the other banks were going with them. Remember, the bailouts didn't come until a few weeks later when the money market funds broke the buck triggering $trillions of withdrawals in what would essentially be a financial system wide run on the bank. The regulators didn't like the idea that a failing bank should be bailed out (as they shouldn't), and they couldn't find a merger partner like they did with Bear Stearns, so they let it fail. The bailouts didn't come until they realized that the fallout from Lehman's failure would bring down the whole system. Yeah, Dick Fuld wasn't really any different than any of the CEO's that got a bailout, but to cast him as the good guy among the group is ridiculous.
Everyone always told me, "don't invest what you can't afford to lose" and that risk mitigation is paramount.

Potentially tanking your firm on a gamble seems reckless and totally ignores the fundamentals of trading.
Shorting more stock than what actually exists is not really that different from shorting less stock than what actually exist.

It's not substantially different from having 100% or 150% more long positions than outstanding shares.

Personally, I think smart people just do this. When I got sick with COVID I cannot begin to describe the number of people who became doctors during this unprecedented time, only to send me outdated comments, articles, and speculation.

All of these people thought they were smarter than the instruction I received from a real doctor, nurse practitioner, and the CDC. These were smart people, though, and mostly (but not limited to) highly educated engineers.
Sorry it didn’t land with you. We’re constantly torn between writing for the one person (a healthcare provider) vs a larger population.

If you have a typical late stage COVID patient, a static patient resource like you described is perfectly fine to look at efficacy of the standard dexamethasone 6mg treatment.

But if you have an atypical patient and considering a 20mg dose, you’re out of luck. Most patients are atypical and we see an unmet need with a long tail of atypical questions.
the devs at factorio have developed an amazing test suite automation system to automate regression tests. I wouldnt be surprised if this is what gives them most of their confidence to do twice daily releases. I thought it was newer, but they seem to have had it for the past 6 years. So i guess my point is they dont need to 100% trust every dev (while I'm sure they could with such a small team) they can instead trust in the tests.

Dick Fuld has said that several times publicly, there are interviews with the FCIC where he said that there was a conspiracy against LEH, and almost every part of the meetings at the NY Fed are public knowledge...you have no behind the scenes knowledge (you sound like every person: I met X who did Y terrible thing, he isn't actually a bad guy, I am going to ignore all the public information about X and prioritise my super special "insider" knowledge).

I will ask you a different question: if LEH was so strong, why didn't the Koreans invest? Why didn't BARC invest before BK? The issue, again and again and as explained at massive length in several books, they had very shaky funding, they had a lot of stuff that no-one knew how to value, they insisted to everyone that this stuff was very very valuable...it was not. If the real estate was so valuable, why couldn't they sell it? Every single person who I have ever met in the same position (I have met many) is in denial...that is why they are in that position. Fuld made numerous mistakes that can be summarised as: he thought he had pocket aces, he had 72o.

Asking Dick Fuld for opinions on Dick Fuld is not smart.
An explanation of why Robinhood restricted trading in the short-squeeze stocks
I also believed that most of the shorts were naked, but the director of S3partner clearly explained how this was not the case. One stock can be shorted multiple times which is what causes the SI% to be over 100%. A lends to B, B sells to C, C lends to D and so forth. Two shorters (B,D) but only 1 original stock.

And Robinhoods closure of the trade seems reasonable in retrospect as well. If the clearing house required a higher collateral to clear trades on those tickers due to their volatility and RH did not have the liquidity to provide it then blocking the purchase of those tickers seems fair.

I can't really see anything illegal about the actions of the traders or the brokerages like Robinhood and Webull.

What would be the best programming language matching his criteria(flexible, concise, static types, DSLs)?
I think what we're finding out now is that this happened as a result of the strength of financial regulations/safety systems in place in the US markets.

Volatility increases risk, and higher risk requires higher levels of safety to operate properly, and Robinhood couldn't provide the higher level of safety, so they were given no choice by the people who actually execute their trades.

In the coming days, more information will add context that, I expect, will make the populist outrage look foolish/uninformed. In many ways, we're already there.
I continue to be shocked at the lack of productive development tools on linux. My current c/c++ toolset is: a makefile generator that I wrote after years of wasting time on autotools problems, Anjuta for debugging and rudimentary editing, and Visual Studio 2008 on Windows XP running in VirtualBox for most productive work (it's a cross platform project).
You could say the exact same thing about the US stock market, except it's moved orders of magnitude more money.

The risk may not be in the same spots as traditional markets, but it's there. Return doesn't come without risk, it comes because of the risk.

Robinhood denies claims that it sold GameStop shares out from under its traders

There are GitHub bots for that. The one I’ve seen (I forget the name) comments afterwards if the template isn’t followed. Perhaps it even allows you to directly close and lock the issue in those situations.

Alternatively, if you’d truly “pay good money” it shouldn’t be hard to find someone to do it for you, reviewing issues and pinging you on the actionable ones. I’d enjoy that work; I like keeping repositories clean.
That's an accurate enough analogy.

When you sell a stock on Robinhood, it takes ~2 days to "clear" the transaction. So, Robinhood credits your account, but Robinhood doesn't see that money for 2 days. They don't allow you to withdraw the money from Robinhood until its cleared, but you can purchase other stocks with the money, and if you do that, Robinhood now needs to send something to the seller. All brokerages, and the clearing houses they work with if they don't self-clear (RH, IB, WeBull, etc do not self-clear; bigger banks do), maintain a level of "float" to handle these payments; its like grease which allows the system to move faster, and the bigger these pools of money, the less risk there is.

Robinhood is the #1 app on the App Store right now. EVERYONE is getting in on this. Many of these users likely joined with an invite code, and Robinhood will give out two random shares of stocks for each of these users ($$). After they're in the app, they're probably using the Instant Deposits feature to trade on up-to $1000 they've started transferring but which hasn't cleared yet (pressure on the float). Many of these users are, in WSB terminology, paper hands; they bought GME @ 250, its at 320 now, they want their gains, so they sell immediately; more pressure on the float.

If that float hits zero, that's basically like, imagine your company's bank account hitting zero, its payday (because every single hour of every day is payday for a brokerage), and you have 50 million employees. People would sell stocks, and the number in their account wouldn't go up. In fact, people couldn't even buy or sell stocks, because that float is used to pay fees on every transaction to their clearing house. Now, people are scared; their faith in robinhood has been shook, and they want out. So, they try to sell stocks; they can't. They're angry. If they have settled funds, they pull those out, which just compounds the problem because now their balance sheets start looking weaker and weaker, which makes access to emergency credit lines harder. Basically, they would implode irrevocably. Even the hint of a liquidity crisis is enough to tarnish a firm's reputation.

IMO, I think the biggest driver of this issue for Robinhood is their instant deposits functionality. That feature is insane, and in market runs like this, deadly. Robinhood hasn't actually "lost" money (well, not enough to cause a liquidity crisis); its just the problem of not having enough money right right now to pay people who need to be paid.

But, the deeper issue is the US financial system and its molasses speed of moving money around. The Fed is making strides to improve this, but it will take a decade or more before we see real change.
