I suggest you not try to sell 5,500 to the crowd at the plate today. I've been trying to find an adult on the buy side most of the day and can't find one.
I found the early exercise kind of strange also. What's to be gained with the put bought against a long stock position? If the price continues to go down, exercise on expiration day. If the price goes up, the long put holder is also long the stock.
I see buying a put against a long stock position as paying an insurance premium to guarantee a minimum exit price for the term of the policy. I can't see making a claim for the minimum price while there is still two weeks left on the insurance policy.
On the other hand, in light of the peanut gallery controlling the batting box recently, exercise was a sure way to sell all 5,500 shares at the strike in one shot.
