Why Is 10x Genomics ($TXG) Stock Down -13.52% Today? TXG shares fell roughly 13.5% in Monday's session, extending a sharp pullback after a multi-month rally that more than tripled the stock. The sell-off was driven primarily by valuation and "bubble" concerns after the stock's rapid run-up left it trading at elevated multiples relative to its still-negative earnings. A regulatory filing for a proposed share sale by an insider affiliate added to the selling pressure and chilled sentiment. Fundamental worries persisted around weaker instrument sales, the company's ongoing losses, and capacity bottlenecks for its new Atera platform. $COIN $BRKR $CLSK $RIOT
