Rosen Law Firm said it is investigating potential securities claims on behalf of shareholders of UP Fintech Holding Limited, whose Nasdaq-listed shares trade under TIGR, over allegations the company may have issued materially misleading business information. The firm said it is preparing a class action seeking recovery of investor losses and that investors who purchased UP Fintech securities may be able to seek compensation through a contingency fee arrangement. The investigation centers on May 22, 2026, when Reuters reported in an article titled "China to crack down on 'illegal' cross-border securities" that China had announced a major crackdown on cross-border investment and would punish brokers it accused of illegally moving money to foreign markets. Reuters said online brokers Tiger, Futu and Longbridge would be penalised for soliciting business in China without an onshore licence. On that news, UP Fintech American Depositary Shares (ADSs, U.S.-listed certificates representing foreign shares) fell 25.3% on May 22, 2026, the law firm said.
