Is STM overvalued in 2026?
STMicroelectronics NV ADR (STM) currently trades at $77.30 per share with a market capitalization of $70,668,018,000.00. Based on our multi-factor framework, the stock appears richly valued with a Smart Value Score of 40/100. This score blends growth quality, financial health, and price attractiveness into a single institutional-grade read.
The stock trades at a P/E ratio of 496.9x, above its 5-year median of 12.5x. The PEG ratio of 0.71 suggests earnings growth is outpacing the multiple, a classic sign of undervaluation.
Looking at its own history, STM is currently trading more expensive than 100% of the last 5Y on P/E. This places it in the 100th percentile of its historical range, a zone where forward returns have typically been muted.
A standard DCF model does not produce reliable output for STM under current conditions. For unprofitable or near-breakeven companies, revenue-based multiples such as EV/Sales and historical P/S percentile are more informative than intrinsic value calculations.
The Piotroski F-Score of 4/9 puts financial quality in a middling range, neither a standout strength nor an obvious red flag.
Bottom line: STM appears richly valued on our framework, with a Smart Value Score of 40/100. At current levels the risk/reward is skewed against the buyer. A materially lower price or significant operational improvement would be needed to change the picture.
