NEW YORK (Reuters) - Hedge fund manager David Einhorn, whose Greenlight Capital suffered its worst year ever in 2018, told investors on Wednesday he had made some changes to the fund's main portfolio, including selling Bayer BAYGn.DE, Mylan MYL.O and Perrigo PRGO.N last year.

Greenlight Capital also sold Apple AAPL.O, which had been previously reported, and the fund manager said he covered short positions in Core Laboratories CLB.N and oil frackers.

“We are looking forward to a new season,” Einhorn said in a letter to investors on Wednesday that was seen by Reuters, after Greenlight’s main fund lost 34 percent in 2018, making it the firm’s worst year ever.

Einhorn listed Brighthouse Financial BHF.O, AerCap AER.N, CONSOL CoalResources CCR.N, General Motors GM.N, Green Brick Partners GRBK.O, Germany's Deutsche Pfandbriefbank PBBG.DE, as well as gold and Puerto Rico GO bonds as long positions, while he is shorting Assured Guaranty AGO.N and Tesla TSLA.O.

At Tesla, he expects a “shortage of demand,” and that the third quarter was “as good as it gets” for the electric car maker, which “faces challenges in 2019.”

CFO TO LEAVE

Einhorn said Harry Brandler, the hedge fund’s chief financial officer, will leave the firm this month after 17 years. He did not immediately name a replacement for Brandler, saying only that he promoted people in the firm’s operations and finance areas.

He said he was reopening his funds to new investments, after years of turning them away.

“At this point, we no longer believe there is risk of our assets growing too quickly (other than through improved performance), so for those interested in investing, the answer will now be ‘yes’.”

The firm’s assets had shrunk to $2.5 billion, from over $10 billion four years ago.

Many investors were fed up with heavy losses and Einhorn said the firm has had “substantial redemptions.”
