A 52 week low and an intraday hammer are your only buy signals? Not enough for me, thats for sure. Trying to pick bottoms is a good way to eat up your account fast. I don't see any compelling reason to get long on INTC right now. The way I see it the next significant resistance level is around $19.50 from Sept 04. The only thing that might save your ass is the volume seems to be drying up a little on this move down even though its still above the yearly average. But that could just start a sucker rally and turn around quick. I would definitely wait for some sort of reversal pattern to form along with confirmation before trying to predict when this loaded freight train finally comes to a stop.
Trade what the market tells you to do, not what you want it to do.
