The U.S. Securities and Exchange Commission has suspended all trading activity in QMMM Holdings Ltd. after the firm’s stock price jumped 959% in just under three weeks. The SEC made the decision on Monday, citing possible price manipulation on social media platforms. QMMM, a Hong Kong-based advertising tech company, had announced on September 9 that it was entering the crypto sector and building a $100 million treasury to buy Bitcoin, Ethereum, and Solana. That announcement triggered a parabolic rally in its share price, pushing it up from penny stock territory into a frenzy of retail attention. The SEC’s trading halt will remain in effect until 11:59 p.m. ET on October 10. The company lists its U.S. shares through a holding firm registered in the Cayman Islands and trades on Nasdaq. Both QMMM and Nasdaq failed to reply to press inquiries submitted after business hours.
