Surely this can't be right. If I write a naked put I am guaranteeing that I will buy someone's stock at X price. Even if the price crashes to 0 then I can only lose the exercise price of the option less the credit received for writing the option.
eg - If I write a $10 put over XYZ company for 50 cents and then have to fulfill the option - then it would cost me $10 less 50 cents for a total loss of a maximum of $9.50 (this assumes I can't onsell the share for any amount).
Or am I missing something??
