Einhorn Deepens Slide as Greenlight Plunges 19% in First Half

David Einhorn's Greenlight Capital has recorded significant losses in the first half of 2018, with the firm's flagship hedge fund declining 7.7% in June alone, according to a client update reviewed by Bloomberg. The cumulative first-half loss of approximately 19% marks a pronounced underperformance relative to major market benchmarks and peer strategies in the value-investing category.

The magnitude of Greenlight's decline stands in stark contrast to broader market performance. The S&P 500 Index delivered positive returns of 2.6% year-to-date through mid-2018 when including reinvested dividends, while the HFRX Global Hedge Fund Index—a widely followed early indicator of hedge fund industry returns—declined only 1% over the same period. More notably, Greenlight underperformed even specialized value-strategy benchmarks: the Hedge Fund Research Inc. Fundamental Value Index, which tracks value-oriented equity hedge funds specifically, gained 1.8% through the first five months of 2018.

The performance gap indicates that Einhorn's long-short equity strategy, which typically employs both long and short positions simultaneously to manage market risk, failed to deliver its intended downside protection during the first half of 2018. The fund's 19% first-half loss represents a significant deterioration from the typical hedge fund experience and underscores challenges within value-focused investing strategies during this period. This represents a deepening slide for Greenlight Capital, positioning the fund well below peers employing similar fundamental value approaches.
