Steve Jobs recently stepped aside as CEO of Apple, taking five months off to deal with health problems stemming from his battle with cancer. If you've been following Apple's stock price, it tends to rise and fall with the health of Jobs.
The Securities and Exchange Commission will be conducting a review of Apple's reveal of Jobs's health to determine if they attempted to manipulate their stock price by concealing or timing the release of information.
An SEC review, however, does not mean guilt is assumed and no one is saying that yet. In fact, Apple stock price has actually gone up since the SEC review was revealed.
