Herbalife Ltd (HLF) is rebounding following a sharp sell-off late Friday as analysts and bloggers take to their keyboards following Friday’s report that the nutritional supplement company is under criminal investigation by the U.S. Department of Justice.

Herbalife Ltd. (NYSE:HLF)¬†followed with a statement that they have “no knowledge of any ongoing investigation by the DOJ or the FBI.”

Technical focus from Trade Ideas LLC likes the stock as a “dead cat bounce” based on trading action that shares were down big yesterday but up big today, plus other proprietary factors, as reported by The Street.

However, several analysts contributing to Seeking Alpha are negative on the company with one writing that the criminal investigation is real and that the company’s suggested lack of knowledge is alarming. Another states several HLF insiders are being targeted for mail and wire fraud. While a third blogger, who is short the stock, explains why the company’s books need to be audited.

Friday’s events follow ongoing attacks from activist investor Bill Ackman’s Pershing Square who contends that the multi-level marketing company is a pyramid scheme that takes advantage of low-income individuals.

HLF is up 8.3% to $55.76 in early Monday trading. Volatility continues to characterize trading in HLF which has a 52-week price range of $34.72 – $83.51 per share.
