Billionaire David Tepper’s hedge fund had a strong first quarter, exiting positions in several major companies while doubling for some tech names. Securities filings released Monday show Tepper’s Appaloosa Management was a primarily stock seller in the first quarter, with two exceptions among his top holdings. The hedge fund manager added to his positions at Amazon and Microsoft during the quarter. One of the notable deals not on the list above is Uber. Appaloosa bought nearly 1.8 million shares of the transportation company in the first quarter, bringing its total shares to more than 2 million. That stake was valued at about $72 million at the end of March. The fund has made some notable moves in the retail industry. Appaloosa closed small positions in Foot Locker and Gap, and trimmed larger positions at Macy’s and Kohl’s. Tepper has also closed positions in homebuilders DR Horton and PulteGroup, General Motors and telecom giant T-Mobile. The positions of T-Mobile and General Motors were both worth more than $100 million at the end of December. The move by GM and retail stock was a reversal of buying in the previous quarter. There were some purchases during the quarter, however, as Appaloosa started two small casino locations in Wynn and Las Vegas Sands. Quarterly securities filings from hedge funds show stocks directly owned by the fund and stock options, but not short positions. Tepper told CNBC’s Jim Cramer last week that he had defended his short position against the Nasdaq. The filing also doesn’t say when exactly the transactions were made, so it’s unclear if Tepper made these transactions early enough in the quarter to avoid a dramatic drop in the stock.
