Third Point LLC, the hedge fund firm run by Daniel Loeb, sold its investment in Sony Corp. and bought stakes in eBay Inc. and Alibaba Group Holding Ltd. in the third quarter.
The New York-based firm also called for a breakup of biotechnology company Amgen Inc. into a "MatureCo and GrowthCo," according to a letter to investors released Tuesday.
Loeb said the firm made "nearly 20 percent" on the Sony investment, which was announced in May 2013, despite the company rejecting his push that it spin off about one-fifth of its U.S.-based entertainment business.
