NEW YORK, Aug 18 (Reuters) - Hedge fund manager Boaz

Weinstein, best known for the London whale trade that cost

JPMorgan Chase ( JPM ) billions in losses and more recent

efforts to shake up the closed-end fund industry, is hiring two

senior partners as his firm, Saba Capital Management, plans to

expand into quantitative credit trading.

New York-based Saba, which invests $6 billion on behalf of

clients, will reunite with Jeremy Benkiewicz, a co-founder of

the firm, early next year, people familiar with the matter said

on Monday. It is also making Kieran Goodwin, who has been

advising the firm, a partner to lead Saba's move into

quantitative credit trading, said the people who are prohibited

from discussing personnel decisions publicly.
