Is LYB overvalued in 2026?
LyondellBasell Industries NV (LYB) currently trades at $63.69 per share with a market capitalization of $20,865,020,000.00. Based on our multi-factor framework, the stock trades at a fair valuation with a Smart Value Score of 65/100. This score blends growth quality, financial health, and price attractiveness into a single institutional-grade read.
LYB currently has no meaningful P/E ratio, which typically signals that the company is unprofitable, near breakeven, or emerging from a loss-making period. With a P/S ratio of 0.7x, the market is valuing the company primarily on its revenue rather than its earnings.
Looking at its own history, LYB is currently trading cheaper than 100% of the last 5Y on P/E. This places it in the 0th percentile of its historical range, a level that has historically coincided with attractive entry points.
Our discounted cash flow model estimates LYB's intrinsic value at $55.45 per share, against the current market price of $63.69. This implies a premium to fair value of -7.25%. The stock is priced close to its estimated fair value, offering limited upside without further operational improvement.
Financial quality is a concern. The Piotroski F-Score of 2/9 flags weakening fundamentals that deserve closer scrutiny before the valuation case can be fully trusted.
Bottom line: LYB trades at a fair valuation on our framework, with a Smart Value Score of 65/100. The valuation is defensible but offers no obvious bargain. Patience or a better entry price may reward disciplined buyers.
Frequently asked questions
Is LYB overvalued?
LYB scores 65/100 on our Smart Value Score (Grade B), a mixed overall profile. On valuation specifically, the DCF puts intrinsic value below the current price, so the stock is expensive on cash flow today. The score reflects growth and quality carrying it, not a cheap entry point.
What is LYB's fair value?
Our DCF model estimates LYB's intrinsic value at $55.45 per share, versus the current price of $63.69, a margin of safety of -7.25%. Fair value is the present value of the cash flows we project the business to produce, so a price above it means the market is paying up for growth the model does not yet assume.
What P/E ratio does LYB trade at?
LYB does not have a meaningful P/E right now, usually a sign of unprofitability or an earnings transition. For unprofitable growth names, price-to-sales is the more useful gauge.
