David Einhorn's bad start to 2018 keeps getting worse.
The Greenlight Capital (Gold), L.P. - Dollar fund, which roughly tracks the firm's flagship fund, dropped 5.7% in February, bringing year-to-date losses to 11.4%, according to a Greenlight client update seen by Business Insider that estimates the returns.
By comparison, the S&P 500 gained 0.67% over the same period, according to Markets Insider data.
Greenlight had already gotten off to a rough start to the year, with the same fund tumbling about 6% in January. The firm's flagship fund returned 1.6% last year after fees, compared with a 21.8% gain in the S&P 500, Business Insider previously reported.
Einhorn said on a conference call last week that Greenlight's performance was the worst since 2000, Bloomberg reported.
A Greenlight spokesman didn't immediately respond to a request for comment.
Greenlight managed $7 billion as of mid-year 2017, per the Absolute Return Billion Dollar Club ranking.
