A worrying trend or a contrarian indicator? Leon Cooperman's Omega Advisors was far from the only big hedge fund to unload its Apple (AAPL) position in Q4. Joining Omega were Dan Loeb's Third Point, Thomas Steyer's Farallon Capital, Barry Rosenstein's Jana Partners, John Burbank's Passport Capital, and Eric Mindich's Elton Park Capital. On the other hand, David Einhorn's Greenlight Capital raised its stake to 1.3M shares from 1.1M and bought 275K call options ahead of its Prop. 2 suit (13F). Apple has historically been a hedge fund darling.
