7. Steve Jobs is the visionary of the century. This one man is the single greatest asset in corporate America, which causes Apple stock to trade with a Steve Jobs premium, a variable that the shorts can use as well. Apple's stock is always vulnerable to losing Jobs. If Steve Ballmer were to leave Microsoft ( MSFT), nobody would care; that doesn't help the shorts. Jobs is different. A hedge fund could float a factual article that gives statistics on liver transplant patients, and it might move the stock. These seven reasons make Apple an ideal short play for sophisticated traders who want to make money coming and going. The chaos of it all can cause individual investors to become frustrated with the volatility. Apple shares closed up $3.57, or 1.9%, to $195.43 on Friday.
