Investors who bought UP Fintech Holding Limited (NASDAQ: TIGR) securities during a period spanning more than two years are being reminded of a December 28, 2026 deadline to seek lead plaintiff status in a UP Fintech securities class action. The case, first filed by Rosen Law Firm, covers purchases made between April 22, 2024 and June 2, 2026, inclusive.
Who the case covers and what investors can do
The class action has already been filed. Anyone who purchased UP Fintech securities during the defined class period may be eligible to participate in any potential recovery without paying upfront costs, according to the firm, through a contingency fee arrangement. Investors who want to serve as lead plaintiff—a representative party who directs the litigation on behalf of other class members—must ask the court to appoint them no later than December 28, 2026.
Rosen Law Firm notes that no class has been certified. Until certification occurs, investors are not represented by counsel unless they retain their own lawyer. They may choose their own counsel, or they may do nothing and remain an absent class member. The ability to share in any future recovery does not depend on serving as lead plaintiff.
Allegations at the center of the lawsuit

According to the complaint, the defendants made false or misleading statements or omitted material information. Specifically, the lawsuit alleges that UP Fintech materially understated its legal and regulatory risk given what the complaint describes as continued illegal activity in China. The suit further claims that statements about the company’s business, operations, and prospects were materially false and misleading or lacked a reasonable basis throughout the relevant period. When the true details became available to the market, the lawsuit says, investors suffered damages.
About the firm behind the filing
Rosen Law Firm describes itself as a global investor rights practice focused on securities class actions and shareholder derivative litigation. The firm states that it achieved the largest-ever securities class action settlement against a Chinese company and was ranked first by ISS Securities Class Action Services for the number of securities class action settlements in 2017. It also says it has been ranked among the top four each year since 2013 and has recovered billions of dollars for investors, including more than $438 million in 2019 alone. Founding partner Laurence Rosen was named a Titan of Plaintiffs’ Bar by Law360 in 2020, according to the firm, and many of its attorneys have been recognized by Lawdragon and Super Lawyers.
The firm also cautions investors to choose counsel carefully, noting that some firms issuing notices do not have comparable experience or resources and may act as middlemen referring clients to firms that actually litigate the cases.
