BOSTON (Reuters) - Hedge fund manager David Einhorn told investors on Tuesday that his Greenlight Capital lost money on battered retailer Macy's Inc <M.N> and exited the position roughly six months after getting in.

"We sold Macy's for a loss after the company announced a significant reduction in full-year 2016 guidance," Einhorn said in a letter seen by Reuters. Macy's and Apple <AAPL>.O> were "material losers" for the firm as it lost 2.6 percent in the second quarter, the letter said.

Greenlight sold Macy's at $32.08 a share after having told investors in January that it had bought the stock at $45.69.
