Quarterly figures matter

Analysts and risks

MarketScreener's analyst panel put STMicroelectronics at a Buy consensus with 20 analysts and an average target price of USD 77.48 on September 21, 2026. The same page showed a current price of EUR 44.65, so the implied gap to the average target remains wide.

The immediate counterpoint is valuation and timing: MarketScreener's own figures imply the stock already trades at a 2026 P/E of 43.1x and an EV/sales multiple of 2.94x. That makes the next catalyst more important than the latest one-day rise.
