5. Apple secrecy. As the unparalleled leader in tech innovation, Apple feels that it is necessary to keep future products veiled to all competitors, consumers and investors. I'm not here to criticize Apple for this practice because it certainly has its merits, but it does open the stock up to volatility. Apple has yet to sell a single Tablet, yet hedge funds already have made millions from rumors surrounding the product. The lack of transparency from Apple creates a perfect storm for short-term traders.
