The article from July 16 (when he was down just 15% YTD) says:
-----------------------------------------------------------------------------------------
Since 2014, Greenlight Capital has made a loss of 25 percent, and 15 percent was lost during 2018-YTD. Bloomberg reports that he has lost about nearly every one of the top 40 positions in his $5.5 billion portfolio this year, though he continues to maintain that “Our investment theses remain intact,” and “Despite recent results, our portfolio should perform well over time.”
He is now being accused of clinging on to his old ways - buying the beaten-down companies he expects to spring back and selling those that he perceives as overvalued - while the industry has moved on.
He is currently long on the cheap General Motors Co. (GM) stock, and short on a basket of stocks including Netflix Inc. (NFLX) and Amazon.com Inc. (AMZN) that he considers as bubbles though they have had big upward runs. Market appears to be apprehensive about his approach that has worked in the past but may not be worth now. A few are wary that his focus has shifted from his earlier money-making small and mid-cap stocks to large-cap ones where there is little room to grow.

This would suggest he is shorting bubble stocks and using large cap dogs as a hedge. And not just this year, he been doing poorly since 2014 according to that link.
His does not sound like a good strategy for the market we had over the last few years.
"Over the past three years, our results have been far worse than we could have imagined, and it's been a bull market to boot," wrote Einhorn. "Right now the market is telling us we are wrong, wrong, wrong about nearly everything."
Much of Greenlight's losses were attributable to wrong-way bets on Tesla Inc. (TSLA) and General Motors Co. (GM).
