Boston-based Ken Heebner is another well-known manager who's off to a poor year. Known as Big Foot for his outsized bets on particular stocks, the mutual fund manager oversees Capital Growth Management's $2.5 billion CGM Focus Fund ( CGMFX). Heebner's clients have been sent on a rollercoaster ride. The fund has sunk almost 20% this year. Even so, the CGM Focus Fund rocketed 80% in 2007 and 67% in 2003, contributing to a 10-year annualized return of 9%. The fund's top holding now is online travel service Priceline.com ( PCLN), at 6.6% of assets. Its shares are up 26% this year, prompting Heebner to sell part of his stake earlier in the year. Heebner has been trading at a furiously fast pace, which is typical for him, as his portfolio turnover rate during the first half of the year was the equivalent of a startling 554% on an annualized basis. That would mean the holdings turn over a total of six times in a year. But he has a huge bet on the consumer-cyclicals sector, and the fund's latest big addition is Herbalife ( HLF), at 6%. The nutritional and household products firm's shares are up 64% this year.
