Greenlight Capital Re, Ltd. (NASDAQ:GLRE) had a very profitable November, according to data posted on the company’s website. The reinsurer was up 4.9 percent in the month of November compared to the S&P 500 (.INX) return of 2.8 percent for the month. Last month, GLRE was only up one percent as losses in short positions detracted from gains in long (as Einhorn noted in the GLRE conference call for the third quarter). The strong returns were helped by longs in technology companies, Apple Inc. (NASDAQ:AAPL), Micron Technology, Inc. (NASDAQ:MU) and Marvell Technology Group Ltd. (NASDAQ:MRVL).
