Battery stocks fall as long-term Treasury yields hit 19-year highs, pressuring speculative growth names.

Shares of battery developers QuantumScape, Enovix, and Solid Power dropped significantly amid rising long-term Treasury yields, which reached a 19-year high. This increase in yields raises the discount rate, hurting the valuations of companies with cash flows expected far in the future, like these pre-revenue battery firms. Despite the sell-off, QuantumScape's fundamentals remain solid with partnerships from Honda and Volkswagen, and upcoming production milestones for all three companies are key to watch. Investors should monitor Treasury yield movements as they heavily influence these stocks' volatility and valuation.
