Allegations of fraud torpedoed the stock of China-based Rino International(RINO_) last month . A short seller had uncovered accounting discrepancies that U.S. regulators, auditors and exchanges had missed.

Rhino International shares drop
Rino came clean, acknowledging in a filing with theSecurities and Exchange Commission that two customer contracts questioned by the shorts had not in fact been signed. Worse, the company said there might be problems with 20% to 40% of its other customer contracts. Rino shares, which had traded near $19 before the trouble started, dropped to $6 when trading was halted Nov. 18. The Nasdaq then delisted the stock, and Rino now trades on the Pink Sheets, recently at around $3.50. All told, investors saw more than $400 million in market value wiped out.
