IONM stock down 99.99% on 04 Feb 2026 (market closed): what traders should watch

IONM stock opened a sharp collapse on 04 Feb 2026 and finished the market closed session at $0.0005, down 99.99% from the prior close of $4.20. The drop erased nearly all market value and left trading volumes at 281 shares, signalling a company-specific liquidity and pricing event. Investors should view this move as an extraordinary loss of value on the NASDAQ in the United States and tie it to balance sheet stress, low average trading interest, and potential corporate actions that drove the price swing.
