Hedge fund manager Dan Loeb sold off huge amounts of stock in technology and media companies during the first quarter, according to a new securities filing. Loeb’s Third Point fund closed out major positions in Google-parent Alphabet and Walt Disney . The fund also sold more than 90% of its shares in Amazon and nearly 70% of its position in Microsoft . All four had been major positions, valued between $300 million and $800 million at the end of December. The filing does not show when exactly the trades were made, but the moves came during a rough first quarter for Wall Street, and tech stocks in particular. Some other notable exits for Loeb included Upstart Holdings and Expedia , which were worth $605 million and $236 million respectively at the end of December. Third Point also left a position in Comcast , the parent company of NBCUniversal, which was worth just over $100 million at the end of December. Outside of tech and media, Loeb also closed positions in RH and Burlington Stores . The fund did pick up some stocks tied to economic growth. Third Point initiated positions in railroad company CSX and Alcoa , worth more than $200 million each, as well as a position in fertilizer maker Mosaic , worth about $85 million. The fund also increased its position in natural gas company EQT . Here are the fund’s top holdings as of March 31. The top holding at the end of first quarter was software company SentinelOne . However, Loeb has since sold some about 6% of his shares in that company, according to other securities filings. Shares of Sentinel have fallen more than 50% year to date.
