Greenlight Capital suffered a setback in March.
The value driven hedge fund headed by David Einhorn dropped 1 percent for the month, missing out on the rally in the S&P 500, which rebounded by 5.2 percent.
Even so, Greenlight is still up 4.4 percent for the year, solidly ahead of the S&P 500, which is down nearly 5 percent, and the Nasdaq Composite, down 9.1
