NEW YORK ( TheStreet) -- Popular searches on the Internet include Herbalife ( HLF) as the nutrition company is reportedly the subject of a Securities and Exchange Commission investigation. According to a report in The Wall Street Journal, the SEC has launched an inquiry into the company. Rumors that Herbalife is a pyramid scheme have swirled for weeks, an allegation the company denies. Pershing Square Capital Management's William Ackman said in December that he had been shorting the stock after determining Herbalife was, indeed, a pyramid scheme. Ackman has sold short about 20 million Herbalife shares. High-profile hedge fund manager Dan Loeb of Third Point LLC, however, came out on Wednesday and said Ackman was wrong. Loeb endorsed the company by disclosing in a filing that his fund owns 8.9 million Herbalife shares. In a statement, Third Point said it began accruing the Herbalife shares "mostly during the panicked selling that followed the short seller's dramatic claims." Herbalife plans to go over its business model thoroughly with investors Thursday at an analyst and investor meeting.
