Is SIMO overvalued in 2026?
Silicon Motion Technology (SIMO) currently trades at $262.05 per share with a market capitalization of $9,388,063,000.00. Based on our multi-factor framework, the stock trades at a fair valuation with a Smart Value Score of 71/100. 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 54.9x, above its 5-year median of 32.7x. The PEG ratio of 0.70 suggests earnings growth is outpacing the multiple, a classic sign of undervaluation.
Looking at its own history, SIMO is currently trading more expensive than 97% of the last 5Y on P/E. This places it in the 97th percentile of its historical range, a zone where forward returns have typically been muted.
Our discounted cash flow model estimates SIMO's intrinsic value at $87.91 per share, against the current market price of $262.05. This implies a premium to fair value of -59.19%. The current price sits well above what projected cash flows justify, implying investors are paying for growth that has not yet materialized.
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: SIMO trades at a fair valuation on our framework, with a Smart Value Score of 71/100. The valuation is defensible but offers no obvious bargain. Patience or a better entry price may reward disciplined buyers.
