At 10:02 a.m., the day-trader advice site Benzinga noted that Apple's stock was down amid "Chatter/Rumors About Steve Jobs' Health." Twenty minutes later Business Insider's Jay Yarow observed that the company's stock was down 1 percent and that he'd been hearing rumors from traders that "Steve Jobs could step down as CEO" via Instant Message.
While the rumors are unsubstantiated at this point, they're possibly a result of the photographs published yesterday of Jobs appearing "sickly and shockingly thin," as the New York Daily News put it.
The 55-year-old CEO is currently on a leave of absence due to "health issues"--something most presume is his battle with cancer. In 2004, Jobs survived a bout of pancreatic cancer and has had a liver transplant. Needless to say, investors are likely on pins and needles today; many people's fortunes are wrapped up in the Cupertino-based company's stock.
