Hedge Fund returns sank for a second straight month in March, the first back-to-back loss since the first two months of 2016, as trade wars, tech-sector woes and a Fed rate hike dragged down the S&P 500 from its mid-month highs and hedge funds into the red for the year. Hedge Funds fell 0.56 percent in the first quarter, compared with a 1.42% gain for the three months ended Feb. 28, according to data compiled in the Bloomberg Hedge Fund Database. Funds also finished the month of March down 0.75 percent, paring losses from February when they fell 2.19 percent.
