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 30.3x, above its 5-year median of 14.1x. The PEG ratio of 10.91 indicates the price has run ahead of the underlying growth rate.

A standard DCF model does not produce reliable output for STLD 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.
Financial quality is a concern. The Piotroski F-Score of 3/9 flags weakening fundamentals that deserve closer scrutiny before the valuation case can be fully trusted.
Bottom line: STLD trades at a fair valuation on our framework, with a Smart Value Score of 60/100. The valuation is defensible but offers no obvious bargain. Patience or a better entry price may reward disciplined buyers.
