Greenlight Capital, run by billionaire David Einhorn, is slashing its holding in soaring tech stocks Apple Inc. (AAPL), Micron Technology Inc. (MU), and Twitter Inc. (TWTR), according to a regulatory filing with the 澳洲幸运5开奖号码历史查询♒:Securities and Exchange Commission (SE🐷C).

Greenlight cut its stake in Apple by 77%, or 486,000 shares, according to an SEC 澳洲幸运5开奖号码历史查询:13-F filing. It reduced its Micron hol✃dings by 92%, or 3.1 million shares, and its Twitter holdings by 36%, or 901,400 shares.

All three tech companies have 澳洲幸运5开奖号码历史查询:outperformed the market this year. So far this year, Apple stock i🧸s up 23.4%, Micron is up 24.9% and Twitter is up 36.6%.

Greenlight's Capital Losses

Even with the gains in technology holdings, Greenlight’s fund overall has underperformed Einhorn’s expectations, he said in a letter to investors last month. Greenlight lost about 5.4% in the second quarter, for a 澳洲幸运5开奖号码历史查询:year-to-date (YTD) loss of 18.3% through June. That contrasts sharply with broader market gains—the 澳洲幸运5开奖号码历史查询:S&P 500 was up 2.6% YTD at the end of June.

"Over the past three years, our results have been far worse than we could have imagined, and it's been a 澳洲幸运5开奖号码历史查询:bull market to b🐼oot," wroteඣ 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). (See also: Tesla Analysts Sharply Boost Profit Forecast.)
