Och-Ziff's 23% Return Lures Investors Even as Shares Falter

````The shares are languishing even though the return of the firm’s flagship OZ Master Fund, which holds 73 percent of its assets, was up 23 percent in 2009 after a 16 percent drop in 2008... For the shares to climb, Och, who declined to be interviewed for this story, needs to grow the firm’s asset base, Lee says. Och-Ziff’s flagship fund was hit by $8 billion in redemptions last year, which helped reduce its assets to $23 billion at the end of 2009 from a peak of $33.8 billion in June 2008, according to company filings... raising pitch has succeeded. In the first quarter of this year, investors poured $2.5 billion into Och-Ziff. ''
