Also is there any broker that will let me have a little margin on GBTC so long as I'm not too concentrated. Uncorrelated assets shouldn't have fully additive margins. The margins in general seem excessive when you're diversified, but too low when you YOLO all in on BABA.

So, there's still no consistency in the amount of margin it requires to go long a SPAC and short the warrant or vice versa. For some spacs it's almost zero, and for others it's fully additive, and for others it's in-between. And every single SPAC will have an interval after the merger where...

They need to hire better programmers.

TWS has a bug that makes it slow to a crawl after it's been open for too long, so I have to restart it every few hours. Not just a matter of personal opinion.

the average hedge fund does worse than an index fund, so who cares.

Bitcoin is the answer.

$200/day * 22 business days/month / 110mbf = $40/mbf/month But may is $120 cheaper than march so you buy the may futures, short the march futures, pay 2 months of penalties and dropship it for a profit of $40/mbf lol. I don't see any clause that voids the transaction after you stall for that...

All copper mines have huge profit margins at $360/lb. This level can't sustain for long because the supply is elastic. I am short three contracts. Not only because it's +EV, but also because it's negatively correlated to equities. When the sh*t hits the fan it's dropping below $2.5

Does the ETF manager just keep it, like a management fee? If so, MOON earns far more for Direxion from stock lending than from the 0.65% management fee. Just the top ten holdings add up to 1.87%.

The only way way AMC and GME can maintain their high stock price is if they issue a lot of new stock at this price and invest it in bitcoin. Shortsellers should be scared shitless of shorting bitcoin.

Can people do anything with it except speculation? At least people actually do something with the real estate in Second Life and the items/gold in World of Warcraft.

Robinhood generates significant revenue from lending its users' shares to shortsellers without telling the users and without giving the users a cut. Robinhood's revenue is like two thirds PFOF and one third stock lending iirc. If shorts are 140% of the float then longs must be 240% of the...

The futures are cash settled so you don't have to cover them at expiration. Also you don't really need to ever cross the spread except in an emergency. I'd just run an MM bot in both markets that has a bias towards being long a larger amount of spot than it's short the futures. Spread your...

Here's a better plan: make the long twice the size of the short, so when bitcoin goes up you just sell some to rebalance and you don't have to touch the futures.

So sit on the asks of all the months and buy spot at the ask whenever you get a fill. The spot bid/ask spread is almost zero.

Step 1: Buy a bunch of spot bitcoin and get 6-10% APY on it as a demand deposit at a regulated exchange Step 2 (optional): Short an equal amount of CME bitcoin futures and get paid 15% APY in contango. That's a 25% return on a delta neutral positon, just for taking some counterparty risk with...

So suppose a CEO posts extra smileys on twitter every time his company is about to beat earnings... that sort of thing? I suppose you could even look up the instagrams of all the insiders and see if they're making big purchases in anticipation of getting bigger bonuses.

Back when I joined IB in 2012, they were the cheapest broker around. But now there are several "commission free" brokers that that get paid by HFT bros for order flow so that the HFT bros can front run you.
