I got a "curtesy" call from ameritrade this morning. Seems that they are going to cover my -1000 shares of ford by the end of the day and charge me brokerage fees for it. The trouble is I want to be short those shares. On the 14th of October I paid 600 dollars for 10 3.00 option contracts (1000 shares). Originally I was protecting my longs but I changed my mind and sold the longs leaving me with the options. The options exercised sat. and I am short 1000 shares of ford at 3.00 Ameritrade however doesn't have the 1000 shares and they are now in a naked short position. So they are trying to force me to cover my short at a loss. Not only do I not want the loss I do not want to cover period. Is it actually my problem they allowed themselves to get into a naked short? What would you guys do?
