David Einhorn used to have a reputation as one of Wall Street's top hedge fund managers. However, over the past three years, Einhorn's star has rapidly faded, and 2018 is shaping up to be one of the worst year's on record for his hedge fund, Greenlight Capital.
For the first half of 2018, Greenlight lost 15.2% of its investors' capital, the worst return since 2015 when Einhorn lost 20.2% of his partners' money. 2017 and 2016 weren't much better. In 2017 Einhorn returned 1.5% and 7.2% in 2016.
