so long as the liquidation had not been completed, don't know why the stock couldn't/wouldn't continue to trade.
i suppose if old sears were to be declared administratively insolvent and the judge dismissed the case and left old sears to just fight it out in court without the protection bankruptcy would otherwise provide the shares might be declared worthless and delisted at that point. but that's just a guess.
