Is the game theory defection dump of the world's biggest hedge fund hotel starting? In a just released 13F filing, Ken Heebner's Capital Growth Management has disclosed that he has reduced his holdings in Apple almost to zero. After holding 1.15 million AAPL shares as of June 30 (which made him holder #100 in the name sorted by size), Ken Heebner who is a regular guest on CNBC courtesy of his bullish tendencies, sold virtually his entire stake, leaving him with just 111,000 shares. One can only speculate about the causes, although it is notable that the last time Heebner did a comparable dump was in late 2008, when after the Lehman bankruptcy he liquidated half his million share stake. Is Heebner sensing something comparable to what happened in late 2008 on the horizon? Or was he satisfying margin calls? Or, most innocently, did he just sell what is probably his most profitable position, "just because" - inquiring minds want to know. We will keep an eye out on who else dumped Apple as the barrage of Q3 13F issuance begins today and ends on Monday.
