DSY, STEC, JEM: Why Are Chinese Holding Stocks Up Today?

Big Tree Cloud Holdings (DSY), Santech Holdings (STEC), and 707 Cayman Holdings Limited (JEM) saw significant stock price increases today, driven by retail traders rather than any official news or SEC filings. DSY surged 645.1%, STEC rose 374.24%, and JEM increased by 166.98%. The trading volumes for these stocks were substantially higher than their three-month averages, indicating a potential risk of a pump and dump scenario. Despite today's gains, all three companies have struggled in 2025, showing substantial year-to-date declines.
Big Tree Cloud Holdings (DSY), Santech Holdings (STEC), and 707 Cayman Holdings Limited (JEM) are making some of the biggest moves this morning. None of these companies have press releases or filings with the Securities and Exchange Commission (SEC) that would explain today's movement. There also doesn't seem to be news out of China that would be attributed to their gains.
Instead, it looks like retail traders are behind today's explosive runs for the Chinese holding company stocks. This isn't too surprising, as these stocks attract penny traders with their low prices, offering easy entry points for acquiring large numbers of shares. That also means there's a real risk of a pump and dump with these stocks. Investors will want to keep that in mind before taking a stake in DSY, STEC, or JEM stock.
