NEW YORK/BOSTON Nov 14 (Reuters) - Top U.S. hedge fund managers in the third quarter bought and sold shares of such hotly debated companies as Herbalife Ltd, J.C. Penney Co and Sotheby's.
Ellington Management Group LLC, a $5.5 billion investment firm founded by Michael Vranos, took a new position in auction house Sotheby's, as did Eric Mindich's Eton Park Capital Management.
Ellington owned 71,500 shares at the end of the third quarter while Eton Park opened an 1.94 million stake.
Daniel Loeb's Third Point, the largest shareholder in New York City-based Sotheby's with a 9.3 percent stake, has been pushing for a management shake-up.
Farallon Capital Management, a San Francisco based-hedge fund, and activist investor Jana Partners LLC opened new positions in ailing retailer J.C. Penney with 500,000 shares and 489,600 shares, respectively.
Patrick McCormack's Tiger Consumer Management, meanwhile, sold out of its entire J.C. Penney exposure, dumping roughly 5.4 million shares.
The quarterly disclosures of manager stock holdings - in so-called 13F filings with the U.S. Securities and Exchange Commission - are always intriguing for investors trying to divine a pattern in what savvy traders are selling and buying.
But relying on the filings to develop an investment strategy comes with some peril, because the disclosures are backward looking and come out 45 days after the end of each quarter.
Still, the filings offer a glimpse into what hedge fund managers saw as opportunities to make money on the long side. The filings don't disclose short positions - bets that a stock will fall in price. And there's also little disclosure on bonds and other securities that do not trade on exchanges.
Upon request, the SEC also permits managers to omit sensitive stock positions from 13F filings. As a result, the public filings don't always present a complete picture of a manager's stock holdings.
Here then are some of the hot stocks and sectors in which hedge fund managers either took new positions or exited from in the third quarter.
VIKING GLOBAL INVESTORS
Andreas Halvorsen's Viking opened a huge new stake in Bank of America Corp of 44.9 million shares. Viking also added 29.9 million shares to its stake in Micron Technology Inc , bringing its exposure to 37.3 million shares.
Viking took a new position in Facebook Inc of 4.4 million class A shares and new stake in Yahoo Inc of 9 million shares. Another new stake held by Viking is that in Lowe's Cos Inc of 17.4 million shares.
Viking sold its entire stake in Apple Inc of 112,200 shares and dumped its entire stake in Boeing Co of 8 million shares.
Leon Cooperman's Omega Advisors opened a stake in Realogy Holdings Corp of about 1.6 million shares and bought 1.2 million shares of Lennar Corp.
Omega increased its Citigroup Inc stake to 3.8 million shares from 2.6 million shares and upped its holdings in PennyMac Mortgage Investment Trust to 2.1 million from about 208,000 shares. Cooperman slightly raised his Motorola Solutions Inc stake to 3.6 million shares.
Omega sold out of its smallish 31,000-share position in Apple and its 4,850-share stake in Google Inc, while shedding Wells Fargo & Co and Las Vegas Sands Corp from its portfolio.

Farallon also opened a position in Microsoft Corp of about 3.8 million shares and bought about 26.8 million shares of Dell Inc, which has since been taken private by founder Michael Dell and Silver Lake Partners.
