1000% Implied Volatility In GameStop

[athlonmank8]

I thought HTZ commented about issuing more shares, but they got blocked by the SEC or decided that they could not because they had already filed or announced intent to file bankruptcy. Bankrupt company can't issue shares.

Oh youre right. My mistake. I forgot about that ruling.

The implied volatility depends on the Black-Scholes formula that has a normal distribution assumption. A normal distribution does not account for the fact that a stock can not go below zero.

The normal distribution used in financial models such as Black-Scholes is on the logarithm of the stock prices, which can be negative.

Yep, the assumption is that logarithmic returns are normally distributed.

thats just one option. there are other models, such as brownian motion with reflecting barrier. probably other models not even published. but there is value in having a model

you can just take the logarithm of 1 plus the price, then it wont be negative. there are many books that discuss this.

I think Tabb discussed in one of his article that the BS model was just that, BS, and that you need to use the pricing arbitrage of the put-call parity to make your option bets

obviously to make the formula fit, you would use the "intrinsic value" as the premium for the missing contracts if you can't find them

but that went over your head
