(Bloomberg) -- Jana Partners, the activist fund run by Barry Rosenstein, named social media firm Facebook Inc. as one of its top long positions.
The New York-based hedge fund listed Facebook as one of its top five long-position holdings in a monthly letter obtained by Bloomberg. Jana previously built and exited a position in the company in late 2017 before selling its stake earlier this year, according to data compiled by Bloomberg.
Facebook has come under fire from top U.S. lawmakers with the clout to regulate the company after it revealed it had data-sharing partnerships with four Chinese consumer device makers, including Huawei Technologies Co.
Jana didn’t disclose the size of its stake or what it intends to do with the investment. A representative for Jana wasn’t immediately available for comment.
The hedge fund also said in the letter it returned 3.1 percent on its investments in May and 2.8 percent year to date. Its investment in jeweler Tiffany & Co. was the biggest contributor to its performance.
“Equity markets moved higher in may as trade tensions between the U.S. and China thawed, economic data came in stronger and corporate earnings were healthy,” it said in the letter.
