(Bloomberg) After one of its best months ever in January, February got hairy for this hedge fund picker. RPM Risk & Portfolio Management, which manages funds of hedge funds, had a return of 13 percent in January for its Evolving CTA Fund. But at the end of the month RPM took down risk after its key indicators showed that a selloff could come. And a selloff did come. Increased volatility has sent shock waves through the markets, with Credit Suisse Group AG liquidating one inverted volatility investment product. Stock markets have plunged, with key indexes down more than 2 percent across the globe so far this year.
