New York Post: Hedge fund heavyweights dumped their stakes in Alibaba during the first quarter after the Chinese e-commerce giant disappointed investors with a revenue miss just a few months after its blockbuster initial public offering. Dan Loeb’s Third Point sold its entire $1 billion, 10-million share stake in Alibaba, while John Paulson dumped his 1.9 million shares by the end of the first quarter, according to quarterly filings of hedge funds’ stock holdings.
