Re: the options vs underlying, after chatting with a friend it seems like this might just be exactly what we’d expect if there is pent up demand to short, but shares aren’t available—there’s an apparent arb available if you go long via options and short via the stock, but you can’t actually execute the arb because shares aren’t available to short. (And the SEC’s uptick rule has been triggered.)
I’m thinking of taking advantage of the options prices via a short strangle (e.g. sell a long-dated $5 call and also sell a long-dated $105 put), but will want to think carefully about it because of the unbounded potential losses.
This page explains why the call option would probably get exercised early and ruin your strategy:
ITM calls get assigned in a hard to borrow stock all the time
The second most common form of assignment is in a hard to borrow stock. Since the ability to short the stock is reduced, selling an ITM call option is the next best thing. A liquidity provider might have to pay a negative cost of carry just to hold a short stock position. Since the market on balance wants to short the stock, the value of the ITM call gets reduced relative to the underlying stock price. Moreover, a liquidity provider might have to exercise all their long calls to come into compliance with REG SHO. That means the short call seller gets assigned.
I was going to say that it’s fine with me if my short call gets assigned and turns into a short position, but your comment on another thread about hard-to-borrow rates made me think I should look up the fees that my brokerage charges.
It looks like they’re a lot. If I’m reading the table below correctly, IB is currently charging 0.4% per day to short NKLA, and it’s been increasing.
Thanks for pointing this out!

The rebate or charge will be passed on to the accountholder in the form of a higher borrow fee, which may exceed short sale proceeds interest credits and result in a net charge to the account.

It’s worse than that. If there weren’t any shares available at your broker for you to short-sell in the market, you should consider it likely that instead of paying 0.4%/day, you just are told you have to buy shares to cover your short from assignment. This is an absolutely normal thing that happens sometimes when it’s hard to find additional people to lend stock (which is happening now).
