The great short:
So, most of you have seen my graph by now and I have checked with the broker. Again, my suspicion was correct. Us retails can't do anything about it.
The underlying condition is a switch up from Smorgasbord's synthetic long, but with a twist. You short the same amount of stock, which result in a type of calendar play. The actual construction is as follows: assuming April 1st where the stock trades around $43. This is how I would construct it:
Naked Short 1000 stock
Buy 10 Jan 14 call option at strike of $45 for $4.5
Sell 10 Jan 14 put option at strike of $45 for $9.8
Which was impossible due to the fact that there's no TSLA stock to borrow. So we go on to the next best thing at about $500 hit to the profit
Sell 10 Apr 13 call option at strike of $25 for $19.9 (luvb2b's ear should perk up at this, remember 3 stooges?)
Buy 10 Jan 14 call option at strike of $45 for $4.5
Sell 10 Jan 14 put option at strike of $45 for $9.8
Since shorting ditm calls is effectively the same as naked shorting the stock. This will work. For every $50,000 you have, you gain $6000. Ah but the stuff doesn't end here. With $50,000 you usually get $100,000 of option purchasing power, which means that the actual amount of capital you get to deploy is $100,000 that nets you $12,000. Which kind of explain why the squeeze didn't happen until the stock jumped up by 40%. (normally it should start at a 20% jump) If you can get a loan from a bank, it is even more.
The trick is, at option expiration, if there are no shares to borrow, you will be forced by the broker to by in (for us retail investors). I am not familiar with how institution works, but I am pretty sure with enough money, I get first dib at TSLA shares to borrow. Which leads to the next phenomena in a perfectly balanced and arbitraged market. Cost to borrow shares. The cost to borrow shares, should roughly equals to the long term benefit of this play, except this structure has no capital risk as long as you are able to borrow shares to short. So where is the profit then?
By looking at the white shape, you probably realized by now that in the long term, the cost to borrow will probably kill your profit if you let it expire, but if the price moves up or down either way, you will be able to exit early.
The reason why this is possible with TSLA is because of big put call premium skew that we've all observed since the beginning and the small shares float. The premium, I suspect, is due to the fact that people think there is a bigger possibility of a TSLA failure than they do of a success. However, since then, it has turned into a feed back loop. High put premium means more people doing this structure and hence more shorting, which leads to even higher put premium (people buying put to short or actually naked shorting stock).
If you were to bring this to any other stock, you have to structure the play in reverse to get the same effect, but will result in only 1 or 2% premium which really doesn't beat any CD at the bank.
So that concludes my analysis and I feel a bit silly since it all comes back to: Can you find any shares to borrow? And as some of the short have found out recently, a calendar play has timing risk, since your short term short might cause a margin call.
