[Caixin] On March 9, the U.S. House of Representatives “Special Committee on U.S.-China Strategic Competition” stated that the committee’s lead member, Ro Khanna (Democrat from California), and Chair John Moolenaar (Republican from Michigan) have written to three U.S. underwriters, requesting materials related to their underwriting of Chinese companies’ initial public offerings (IPOs) in the U.S. market by March 13. They accused these IPOs of deceiving American investors through market manipulation.

The letter states that this type of market manipulation mainly manifests as “ramp-and-dump” after the new stock is listed, leading U.S. retail investors to buy at high prices, while the stock price then plummets by over 90% in a short period. U.S. financial intermediaries are said to have facilitated such manipulative behaviors.
