US hedge funds scooped up shares in Alibaba Group Holding in the third quarter, making the e-commerce giant one of the most commonly bought stocks among some of the biggest US investors, according to regulatory filings on Friday.

Among the institutional investors that took new stakes in Alibaba were Soros Fund Management, the hedge fund firm founded by billionaire George Soros; Jana Partners, the $11 billion hedge fund run by Barry Rosenstein; Janus Capital Management; Tiger Management; Louis Bacon's Moore Capital Management; John Paulson's Paulson & Co; David Tepper's Appaloosa Management; Dan Loeb's Third Point; Viking Global Investors LP; and Leon Cooperman's Omega Advisors.

Alibaba made its market debut in late September in a $25 billion IPO that ranked as the largest ever. Since pricing at $68 per share in the IPO, the stock has surged to about $115.

The 10 hedge funds bought the following stakes in Alibaba: Viking Global had 11.4 million Alibaba shares with a $1 billion market value; Soros Fund Management, 4.4 million shares; Paulson & Co, 1.9 million shares; Third Point, 7.2 million shares; Janus Capital Management, 3.464 million shares; Moore Capital, 1.52 million shares; Omega Advisors, 410,000 shares; Jana, 300,000 shares; Appaloosa, 725,000; and Tiger Management, 1.216 million shares, making Alibaba the largest single holding listed on Tiger's 13F form filed with regulators on Friday.

From Alibaba's IPO through the close of the third quarter on September 30, the company's shares peaked at $99.70, suggesting, for example, that Janus paid at most $345.36 million for its stake. At the $68 IPO price, the same stake would have cost $235.55 million.

Jana, Soros, Paulson and Appaloosa all declined to comment. Viking, Janus, Tiger Management, Moore, Omega and Third Point did not immediately respond to requests for comment. Alibaba did not immediately return a request for comment.

While many stocks struggle after hype-laden debuts, Alibaba has advanced.

Mark Yusko, head of the $4 billion Morgan Creek Asset Management, told Reuters last month that the shares could more than double in the next three years. That could vault Alibaba past Apple Inc's current valuation, which ranks it as the world's biggest publicly traded company.

Yusko said Morgan Creek has bought Alibaba steadily, both before and as the company went public.

Last week, Alibaba founder Jack Ma Yun, who is also the executive chairman, said the company's financial services arm "will definitely go public," and is looking at a listing in the Chinese mainland for the e-commerce company's crown jewel.

Alipay, part of Alibaba's Ant Financial Services Group, is the lifeblood of the company's e-commerce network and China's dominant online payment processor, making it in the eyes of some analysts one of the most valuable assets in the Alibaba universe.

Friday's 13F filings provide a window onto the strategies of some of the world's biggest investors. But the view is limited. The documents look back to the previous quarter, and they do not disclose short positions.

The US Securities and Exchange Commission sometimes allows managers not to disclose sensitive positions.
