OK, here are some stupid questions ... but I would really appreciate knowing the answers to these. if I short WCOME on IB and then it is delisisted and it is a pink sheet stock, how can I cover my short on IB ? if I short WCOME on IB and it goes to bankruptcy and the stock is decalred worthless, how do I cover my short (or do I need to ?) In both of these cases, when would the cash reappear in my trading account ? Other than the possibility of a WCOME recovery, what possible ways could I get screwed on this play ? i.e. why is this a bad idea ???
