A U.S. congressional committee has launched an investigation into three American brokerages over their roles in initial public offerings (IPOs) of Chinese companies that allegedly defrauded U.S. investors through market manipulation.

In letters sent Monday, the House Select Committee on the Strategic Competition Between the United States and the Chinese Communist Party demanded that D. Boral Capital, Dominari Securities and Revere Securities provide materials related to their underwriting of the IPOs. The committee, led by Chairman John Moolenaar and ranking member Ro Khanna, alleges the offerings were part of “ramp-and-dump” schemes in which share prices were artificially inflated after listing before collapsing, leaving U.S. retail investors with significant losses.
