It is alleged that six Chinese citizens and Prestige Trade Investments Ltd. reaped more than $9 million by trading in  Zhongpin ahead of an announcement of a proposal to take the  company private.   The seven defendants bought substantial quantities of common stock and  call options in Zhongpin between March 14 and March 26.  Zhongpin’s stock  price jumped 21.8% on March 27 when the company publicly announced that  its Chairman and CEO Xianfu Zhu had made a non-binding offer to acquire  all of Zhongpin’s outstanding stock at $13.50 a share, a 46% premium  over the previous day’s closing price.
As a result, the SEC has  obtained a court-ordered freeze of the assets of six Chinese citizens  and one British Virgin Islands entity charged with insider trading in  Zhongpin Inc., a China-based pork processor whose shares trade in the  U.S.
