In an emergency action filed in the U.S. District Court for the
District of Massachusetts, the SEC charged and obtained an asset
freeze against 18 China-based traders (see here and here) for conducting a market manipulation
scheme involving approximately 3,000 U.S.-listed securities.
According to the SEC, the traders artificially
influenced the prices of the publicly traded securities by creating
the false appearance of trading interest and activity in the stocks
through the accounts of several different brokerage firms. The SEC
claims that as a result of misrepresenting the trading interest and
activity in certain stocks, the traders were able to gain over $31
million in illegally obtained proceeds.
