The U.S. House of Representatives has initiated an investigation into Wall Street underwriters, including Dominari Securities, which is linked to the Trump family, over allegations of facilitating market manipulation in IPOs of Chinese companies. Committee Chair John Moolenaar and Ranking Democrat Ro Khanna have sent inquiry letters to three agencies, seeking details on their underwriting activities. The firms under scrutiny are D. Boral Capital, Dominari Securities, and Revere Securities. The investigation focuses on accusations that these companies engaged in 'ramp-and-dump' schemes, where Chinese shell companies allegedly manipulated stock prices through coordinated trading and market promotion. This involved inflating stock prices and then selling shares to retail investors at peak levels, leading to significant price drops. Evidence suggests that numerous accounts placed similar buy orders above IPO prices, temporarily boosting valuations before insiders offloaded their shares.
