Robinhood's collateral requirements increase when their users buy stock, and decrease when their users sell stock.

If they hit their collateral limits, they have two options.

1. Stop all trading for a few days, as the trades settle, the funds clear, and the collateral requirements drop. Cue millions of pissed users who want to close their positions, but can't.

2. Only stop trades that increase their collateral requirements - buys.

There's also option 3 which is 'immediately get kicked off the settlement networks and go into bankruptcy, because they are trading past their collateral requirements.'

Which of these three options would manipulate the stock price less, and screw over fewer people, in your estimate?
> There is no upside to allowing them in

I get what you are saying, and agree with your decision to not talk to the police, but it isn’t true that there can be NO upside to talking to the police.

For all the bad things police do, they DO also solve some crimes and arrest some dangerous people. If someone killed one of my loved ones, I would hope the police would be able to find, arrest, and successfully prosecute the murderer.

If no witness will speak to the police, it makes solving a homicide much more difficult.

This is why the current approach to policing is so awful. We should work on fixing the system so talking to the police is a good thing.
I can confirm this is also my status. Thanks for the reassurance that it's not just my instance.
The author did not flied ofd the handle and was not childish.

The author experiences emotion which the author recognized, controlled, analyzed where it came from. The emotion itself helped the to realize long term pattern of behavior of the other person and think about it more and decide what to do about it.

So it was both useful emotion and author succesfully controlled reaction to it. What is also good is that author does not pretend the emotion did not existed and is not trying to pretend that everything was pure logic whole time.

The proposed remedy isn't to punish the lying cops, but to make the confessions obtained that way inadmissible.
The only honest answer the CEO can give is “we are a thinly capitalized startup with a unique business model, that meant when the DTCC jacked margin requirements on BME further trades would have pushed us into insolvency”

Err, same in America man. Bushes? Father and son were the president. Kennedys? Brothers were almost presidents, one was a President, the other governor. Clintons? Spouses were almost presidents! If that's not cliquey I don't know what is.

Your mate is also massively over-egging how bad it is, there is still an Eton clique (the present/last government being a good example), but we've had a range of recent prime minister's educated normally, outside of the Eton clique. Brown, Blair, even Thatcher just went to a Grammar school (generally a better school you have to pass exams to qualify for, which is semi-meritocratic, though gamed by the rich)

Our election system is even worse than America's though so we keep getting conservative governments who win 40-45% of the popular vote but somehow get landslide majorities.

Also, what do you mean by "small", it's got 70 million inhabitants. At worst a country with a population of a size of France and Germany might be called "medium".

Does it actually matter if I can? Is using reference material a bad thing?

Edit:
I know the article touches on that idea briefly but my argument would be "of course it doesn't matter".

Sure, I could develop slightly faster with a more encyclopedic memory but I really doubt it would make an observable difference in the long-term.

Most of my time isn't spent referencing libraries or syntax but instead I spend most of my time thinking out the logic and higher level relationships of my code. I suspect that is largely the case of any development even remotely non-trivial.
Those companies provide the foundation of pensions (including German ones in many cases), give opportunity for people to move social ladders, provide jobs, etc.

Money also is the most universal proxy for value you're going to find anywhere, and for those seeking to maximize their chances to get the most of it - the US is the place to be right now.

Which is also why there is so much demand immigration wise (along with not terrible schools, reasonable social discourse, stable govern't comparatively, etc.) - if you're an up and coming, ambitious person looking to make it big, there is no better place in the world right now, with some notable edge cases. (China for instance, but only if you're Chinese).

Germans (and most Western Europeans, but definitely not Eastern Europeans from what I've seen!) currently prioritize social stability and a base level of comfort and care over over the possibility of getting (individually) filthy rich.

There are pros and cons to this, obviously, and different people will weight them differently based on their backgrounds.

One downside of markdown being so flexible is that it's hard to remember if a given dialect implements a certain feature, or how it will handle a certain corner case

I think I see the appeal of specifying a robust subset of markdown, something that you can trust will probably be parsed the same way for as many dialects as possible.
One example of such a short sell was the report by Hindenburg research about NKLA [0], which also discloses their short position. The net outcome of such disclosures is that fraudulent activity is exposed, the people shorting the stock make a profit, the people who were holding the stock still have their shares, and hopefully new investors are more informed about the stock that's being shorted.

Not all short sellers take this approach though, they could just short the stock because they think it's overvalued. It seems that it's what happened here, but ended up on the wrong side of the trade when WSB decided to buy GME.

It seems like the gloves have come off wrt the idea of fair(ish) vaccine access across the board recently.

I'm usually not much of an aficionado of free market radicalism, but I suspect that the vaccine ramp-up would go better, eventually better for everyone, if it had started with a honest commitment to the highest bidder mindset that we can't goodwill out of existence anyways. Only suspect, because who knows what failure modes the other path would hold, but I think that for example early arrangements for mandatory sublicensing (in case of research success) would have been much more likely to have found their way into research subsidy contracts if nation state representatives had been in a gloves-off situation from the beginning.

Interesting I suppose I didn't realize the exact definition of "naked" -- I was regarding "not naked" a bit more abstractly as "protected from inability to purchase the share when required" with "naked" implying that you did not have that protection ...

To me the deviation from the abstract definition above almost Seems like a bug in the "borrow checker" ... I'm not totally clear on why the system is designed allow the same stock to be "loaned" multiple times in this manner ...

Why is this (not particularly sound) definition of "borrow" desirable ...? I suppose this scheme has the effect of making assets appear more liquid than they might actually be -- but -- why is that good?

Doesn't it seem like there's a kind of bias introduced by this "illusion of more liquidity". Saying this mechanism "increases liquidity" feels almost like putting grease on a slope and saying "the slope is steeper" ...
We let big players partake in risky things like shorting GME above 100% float because we don't care if they lose. It's the same reason we allow them to invest in companies like Theranos. They know the risks they were getting into and will still be fine without a extra 0 in their bank account. Regular followers of WSB are aware of the risks as well, so I'm fine with them attempting a short squeeze. The problem is that they're encouraging regular people to join their crusade against hedge funds who are most likely going to time the market incorrectly. What's worse is that most of the world, including politicians are cheering them on.

Police barely ever solve crimes. Murder, the most serious crime, is hardly ever solved. There is no fixing the situation with talking to police, how would you fix the system? It would take decades of action on the part of the police to regain the public’s trust. One wrong move by one cop, one time would reset that back to zero.

"The short interest staying at a similar range means nobody has closed out their old positions so we can keep squeezing" seems to be a big one.

If you assume that new short positions are being opened - and at the recent prices, that's not an entirely unattractive thing to do - then the short interest staying steady suggests some positions being closed and others being opened, and tells you little about single actors.

And anyone opening short positions at today's prices is basically "resetting the clock" on how long you'd need to squeeze to get them to back down... so if I were to sell it short now, I'd be betting that some folks making some of their first investments ever to ride the hype train are going to be more likely to blink first than I am.
"Human exploitative pattern" or "human manipulative pattern" makes me instantly pay attention and on edge. They are proactively exploiting/manipulating our brain's cognitive processing/award system/neural addiction pathways on a subconscious level and massive scale, which needs to be identified and categorized for all to see... cause we didn't evolve any cognitive firewalls to stop bad actors from intentionally nudging us to make bad choices that they profit from while pulling our levers that they gathered from data signals to dial up the deception and trickery to a science that predicts our probable actions to a degree of accuracy that is terrifyingly accurate.

This is just like the marketing and advertising industries playing emotional music and showing humans doing things that pull on our "heart strings" to get us to buy their crap they are peddling. We need protections from tech company dark patterns and cognitive processing manipulation/trickery.

Yes I think you're approaching it from a way better angle.
Not really - they only allowed buying to bring the total position to 5 shares, and then lowered that to 2 shares and now 1 share!

And if you already held more than that quantity of shares you couldn’t buy more shares.

In the excellent true crime book, "Homicide: A Year on the Killing Streets", David Simon (future creator of The Wire), talks about the Miranda warning in the context of interrogations. When originally introduced, law enforcement bemoaned that this would hamstring their ability to gain confessions from suspects, because any sensible criminal would simply ask for a lawyer. He then goes on to explain that wily police detectives, instead, were able to use Miranda as a tool - "this is something we have to get out of the way so we can get you home" and "look, you can get a lawyer, but then we can't figure this out right here".

He points out that lying to suspects is both a tool and a risk - if you tell a suspect that there was blood found on his shoes, and the suspect knows that he wasn't wearing those shoes during the crime, he knows you have nothing.

I highlight this because it's fine and good to ban lying to suspects, but not all lies are strictly untrue, and it's possible to use partially true statements to one's benefit in an interrogation. Simon points out that interrogations, by their very nature, are coercive, and if we really want to protect the rights of suspects, mandating an attorney present at an interview is the only way to ensure that.
>If I am willing to tie up some money holding an instrument afloat at overvalued prices longer than you are willing to remain in your short position, haven't we ultimately, together in our conflict, created a useful message about the underlying asset?

Exactly. Addressing your example, as it's a good one: To be blunt, me risking the legal standing or overall safety of my family just to bring your family some closure is not a trade-off I'm willing to make. I'm genuinely sorry because I would absolutely like to help, but the downside risk is too great.

I am in an incredibly privileged position in our society, and I've gotten grief at the hands of the police while I was being a "good citizen" and offering information. Never again. If they want to know something we will be doing it in full view of the public out on the street or with my lawyer present.
I'm also curious about what dates were agreed. Looking at the document, here's what they state regarding manufacturing and supply (emphasis mine):

"5. Manufacturing and Supply.

5.1. Initial Europe Doses. AstraZeneca shall use its Best Reasonable Efforts to manufacture the Initial Europe Doses within the EU for distribution, and to deliver to the Distribution Hubs, following EU marketing authorisation, as set forth more fully in Section 7.1. approximately [censored] 2020 [censored] Q1 2021, and (iii) the remainder of the Initial Europe Doses by the end of [censored]"

It looks like the EU expected to have the vaccine approved by the end of 2020 and delivered soon after that. Based on media reporting, it would appear that AZ notified the EU that it would not meet the first deadline, but did so with only a short notice (15 days according to some outlets?).

Without getting into speculation, one date that isn't censored is that which specifies when the "Additional Doses" would stop being offered at the agreed price: 1 July 2021:

"9.3.Additional Doses. AstraZeneca shall provide any agreed Additional Doses at Cost of Goods until 1 July 2021, unless AstraZeneca determines in good faith that the COVID-19 Pandemic has not ceased as of 1 July 2021, in which case AstraZeneca shall [censored]"

So, if the initial doses are delayed, then the optional doses are delayed after that, and then the additional doses are delayed after that, it would seem that the agreed prices would only apply for a small fraction of the additional doses that would've been expected, whatever seemed reasonable. It seems that any delays in the "Initial Doses" could have an effect on the rest of the contract agreement.
They didn’t manipulate squat, they were fighting to save their life. If they were manipulating GME price they would have tried to pump it higher because each time it crashed their DTCC margin requirements went up.

Driving GME price down before all these trades clear likely kills Robinhood.

I understand where you’re coming from, but if they halted selling and it came out that people were stuck in positions they couldn’t sell out of, people who wanted to sell and couldn’t would be even madder than people who wanted to buy are now (and might also have more legal standing.)

Put another way, just because they have to halt buying, they don’t owe it to their customers who are holding to not allow other customers who want to sell to do so.
> Don't most brokers allow you to continue trading before settlement? (so someone has to put collateral for that)

Sure, but I wonder why RH didn't just change their rules to being that you won't be able to trade instantly with any sold GME, and then used client funds as collateral? This seems much better than stopping buying altogether. I suppose maybe the code wasn't in place for something like this, idk.
(Upvoted since your comment was turning gray. It's a legitimate concern, I think.)

I think the story here is that they were overwhelmed with a high demand during the past "WFH and improve your home year" all while their production and shipment capacity was being more or less randomly reduced (separately in each country) with very little warning.

Stock sync issues? I used to think they had bugs there until I realized they're constrained in two aspects that are both unusually tight at the moment:

a) forecasted availability of products in your particular shipment center

b) forecasted availability of home delivery capacity in your particular region

Note that the two will have to match up for the same week at least (maybe less), or there'll be a pileup. In a normal year this isn't really a problem, there's some slack...

The strategy I eventually landed on was to give up trying to bundle everything into one neat order to save a little money. I've been ordering large/heavy stuff (like sofas/beds) for home delivery in separate deliveries, as soon as I've been able to decide on something. Smaller things I've been picking up outside their nearby store. If I didn't live near an IKEA, I'd order the smaller items by postal/package delivery.
