If my position (book value) is 10k and it goes bk then I have lost 10k.
How much would 1500 7 strike options be worth if price goes to 0?
Have you considered how much would you lose if it didn't go below the strike? Take the highest strike on the put of $10 for example, what if the underlying's price by Oct. 18 is $11? You would've lost on your underlying's long position(s) and $10K on the options. Double-whammy. Going OTM saves you on the cost but since the options is so OTM that its chance of becoming ITM is so low that it's almost a guaranteed loss unless it actually has a very high chance of becoming ITM but then if that's the case, its price wouldn't be cheap cuz everybody will be bidding on them. The reason why the price is so cheap is because everybody knows the probability of them becoming ITM is so low unless you have some insider information that GME is going to go bankrupt by October of this year otherwise it's $10K in the water for you guaranteed or I should say almost guaranteed.
That's why I said that's not how you hedge.
