Do a proper fundamental analysis and estimate the true value of APT this weekend and if the current market price is far greater than the value you obtain exit your position, but if you get a value equal/greater than the current market price retain your position.

NB: Panic often bring a stock close to its intrinsic value and APT panic began yesterday (Friday) afternoon. When the stock falls close to its intrinsic value, Directors & Insto will start increasing their holding (in the hundredth thousands or millions) and future competitors like Visa might start considering acquisition at that price. (Nobody will pay $6 billion for APT with its current Net Asset, If your a Fund Manager would you?)
