Key Soros Herbalife architect out

Soros's Herbalife bull gone

The chief architect of Soros Fund Management's bullish bet on Herbalife has quietly departed.

Paul Sohn, a portfolio manager at billionaire George Soros' influential personal investing shop, left the firm late last year, according to people familiar with the situation.

Sohn did not immediately respond to a request for comment.

"Paul Sohn's departure is unrelated to any position the firm may have or has had in Herbalife," Michael Vachon, a spokesman for Soros said in an email to CNBC.
