A coterie of high-profile investors, including Bill Ackman of Pershing Square, Boaz Weinstein of Saba Capital Management and Marc Lasry of Avenue Capital Group, is pushing to buy Sculptor Capital, the successor to the storied hedge fund Och-Ziff — even though the fund has already agreed to sell itself to another investment firm. On Thursday, they gained an important supporter. That deal would value the firm’s class A shares at $11.15, around 18 percent more than they were worth the day it was announced. But shares of the hedge fund have fallen significantly over a longer period, dropping 60 percent over the past two years. The consortium’s most recent offer for Sculptor, disclosed on Wednesday, would value it at about $12.76 for each of its class A shares.
