(Reuters) – Chinese mobile security software maker NQ Mobile Inc said a special committee had found no evidence of fraud, as alleged by short-seller Muddy Waters Research Group. NQ Mobile’s shares rose about 30 percent in premarket trading. NQ Mobile also said the committee also found no evidence that the company’s revenues and cash balances were inconsistent with public disclosures. Muddy Waters called NQ Mobile a “massive fraud” in October, a charge NQ Mobile rejected as false.
