According to the source, the U.S. Securities and Exchange Commission temporarily suspended trading in QMMM after the stock jumped roughly 2,000% in recent sessions (source: the provided source). The company is described as a Bitcoin (BTC) and Ethereum (ETH) treasury firm, making the ticker a crypto-exposed equity proxy (source: the provided source). Under the Securities Exchange Act Section 12(k), SEC trading suspensions can last up to 10 business days, and brokers’ ability to publish quotations upon resumption is restricted by Rule 15c2-11, which can impair liquidity and widen spreads at the reopen (source: Securities Exchange Act Section 12(k); SEC Rule 15c2-11 guidance). For traders, the reopen typically carries elevated gap and execution slippage risk due to limited dealer quotations and constrained liquidity under these rules (source: Securities Exchange Act Section 12(k); SEC Rule 15c2-11 guidance).
