Robinhood restricts their users from buying GME stock.
There are couple of conspiracy theories explaining this restriction:

Conspiracy theory #1
Biden administration prohibits GME trading:

One Reddit user, Odin19199, claiming to be an employee of Robinhood, stated that the company was pressured to halt GameStop trading by Sequoia Capital and the White House. These allegations have not been independently confirmed by Breaking911.

In the post, he alleges that he overheard that “Vladimir, yes founder Vladimir [Tenev], and the C-Suite, received calls from Sequoia Capital and the White House that pressured into closing trading on GME.”

Conspiracy theory #2
Citadel (Robinhood's stock trading execution partner) wants to penalize GME - to suppress GME price - in order to help Melvin's fund with their GME short position:

Robinhood doesn't actually execute any trades. They sell user's trade orders to Citadel, a trade executor. Citadel then buys the shares on the market, and sells them to Robinhood for a slight markup. It's how Robinhood offers trades for $0 fees. You pay pennies more per share, but don't have to spend $5 per trade.

Citadel, and other trade executors, are refusing to buy shares for retail traders. Coincidentally, Citadel also bailed out Melvin fund for their short position in GME. So, Citadel has an interest in not letting the price go up any further. And citadel controls trade execution for dozens of firms.

This is definitely illegal. But Citadel is betting that the resulting SEC fines from this illegal manipulation will be less than the loss they would get if they didn't suppress the price.

Actual explanation
Robinhood restricts buying GME because Robinhood has problems with liquidity.

Because if RH were to collapse the clearing house would be left holding the bag. And clearing houses don't have that kind of money. So DTCC (the main clearing house) going under would stop pretty much all trading in the US.
So the clearing house requires 100% collateral for some stocks now instead of up to 5%. RH can't afford that and GME has been eating up 50% of RH daily trades.

Vlad Tenev claims that Robinhood has no liquidity problems.

When financial institution publicly claims that they have no liquidity problems - there is a good chance that this financial institution, actually, has liquidity problems.

Reading between the lines, they ran out of capital to post the required collateral for the trades.
They've been dancing around the subject because they don't want to trigger a bank run, but this is likely why they had to suddenly raise $1 billion and draw down their credit lines yesterday.

It appears they reached a point where they simply couldn't afford to support the buy orders on the volatile stocks any more. They likely had 2 options:

1) Shut down the entire platform until they could raise enough additional capital to post the required collateral. It's difficult to retain users and raise another round if you literally have to turn your service off on the hottest trading day every.

2) Shut down buy orders on the few stocks that were driving the capital requirements over the limit, at least allowing users to continue to sell.

Why would RH have liquidity problems? Did it short GME too? Did its client short GME and can't provide the collateral now? In the second case the solution is easy: close the clients' positions.

> Because Robinhood customers operate on margin.

Do they? How do you know? Anyway, even if they do operate on margin, if they stock they've bought on margin goes up, there is no liquidity problem.

Note also that buying on margin requires other securities to be held in the account as a collateral.

The only problem would be if they shorted</> GME.

> They bought GME on margin for too high and now GME dropped.

GME dropped after and as a result of RH's restrictions. And why would that make RH want to drive GME price further down?

> So the clearing house requires 100% collateral for GME.

It's not what they did. They stopped all the purchases of GME. Apparently, including the cash accounts.

Whan you buy stock, you actually pay the money during settlement a couple of days later. No margin involved. Every single broker allows to buy stock immediately with proceeds of the sale of stock, in cash account.

> So the clearing house requires a collateral for significantly overpriced stocks - in order to cover their risks.

And the broker passes it through to the clients.

> For example, buying GME on margin when GME is high -- allows Robinhood customer to lose more than they have [when GME will fall].

No, it doesn't. They can't lose more than they've already paid. Short selling is a different matter, there you lose as much as the difference between what you received and the current price, which can be theoretically unlimited.

>> GME dropped after and as a result of RH's restrictions.
> How do you know that?

Becuae they changed the balance of buying and selling. And guess what, next day it went up again.

> Even "cash accounts" need margin for 2 days, because stock trades are not settled for 2 days.

That's exactly why they DON'T need margin.

I'm sure that they do a verification on the check before trading with it and have a limit on the amount available before full clearing, just like the banks do. Anyway, that's a one-time event.

Which is no reason to stop trading for the customers with established accounts.

You don't issue debt unless the customer has enough other collateral in the first place. The risk with the long positions is always limited to the price paid. And then you can always sell customer's stock if the collateral becomes insufficient.

Also, I don't think you understand what a pump-and-dump scheme is. To do that you have to hold the short positions, ideally opened at the top. In the current situation, the pump-and-dumpers got screwed.

> If Robinhood customer bought GME for $300/share and 5 days later GME dropped back to $6/share -- what exactly is Robinhood going to sell in order to cover customer's debt they accumulated.

All their GME shares and all their other shares that were used as collateral, in the amount sufficient to cover the losses.

Only in the case of a sudden and massive market collapse. And even then there would likely be enough collateral for the broker to do an urgent sale and cover the margin, because usually more collateral is required than the margin amount. The collapse would have to be very sudden to exceed this safety.

If the customer hods other stock too, it would serve as collateral. That other stock is not likely to collapse.

OK, so I misunderstood that. In this case I don't see any issues with margin. The stocks get sold at a profit.

And why do they think they have the right to prevent their customers from buying the stock with their own money?

"With their own money". No debt.

No, they don't. Remember, you actually pay for the stock at settlement, a couple of days later. So if you sell and buy stock, you get money at settlement and then immediately pass it along for the buying settlement. You don't need a margin account to do this, it works fine in a cash account.

So do I at my broker. But seeing money and extracting it are different things. You can't extract that money until after settlement.
