About 3 years ago, I came upon a situation where I had to resort to selling a stock, and then excercising it. There was a huge spread on bid and ask. And the bid wasnt reflecting the value of the options by 20 cents. I held 310 2.50 put options on mirant. And I was in a sticky situation because the options were 3 days from expiring. I asked if he could sell, and then excercise. He said sure. And it was done. But at another broker 6 years ago, i came upon another situation like that, and he gave me a long winded excuse that he can't do that. It is against regulations. My question is why do some brokers allow selling, and then assigning? And why do some brokers only allow shorting and assigning?
