Eileen Rominger, chief investment officer at Goldman Sachs Asset Management, is to step down at the end of the year and will not be replaced; the latest in a series of recent, high-profile personnel changes at the firm.

Rominger, who was GSAM's first-ever CIO when she was promoted to the role in April last year, was in overall charge of the firm's fundamental equities, quantitative strategies, fixed income and hedge fund divisions.
