Brevan Howard Shuts Star Trader's Hedge Fund in Push to Hold Cash for Longer

Brevan Howard Asset Management is shutting a hedge fund run by its star trader Ville Helske as the investment firm focuses on increasing the duration of the capital it manages to gain a more stable asset base.

The Brevan Howard Global Volatility Fund that Helske helms is returning capital to investors, according to people with knowledge of the matter. The fund, managing about $379 million, lacked scale and allowed investors to take their money out more frequently, said one of the people, who all asked not to be identified discussing private information.
