how can i remove the movement of the stock market as a whole from the movement in price of an individual share?

the portion of a stock movement not correlated with stocks in general is called alpha. i don't know of any online tools to graph alpha. keep in mind that a company like apple is so huge right now that any properly weighted index will have to correlate with it to some degree.
