Best MaterialsStocks — Ranked by 5 Models

There are really two sectors hiding inside Materials, and they behave nothing alike. Specialty chemical companies like Linde and Sherwin-Williams have pricing power, stable margins, and predictable earnings — they score 6-8 on the composite and look like quality industrials. Commodity producers like Freeport-McMoRan and Newmont have earnings that can swing 300% between cycle peaks and troughs — their scores fluctuate just as violently.

This split is why our calibration emphasizes earnings normalization. The Graham fair value model uses multi-year earnings averages specifically to prevent the classic commodity trap: overvaluing a mining company at peak earnings (when P/E looks low but profits are unsustainably high) or dismissing it at the trough (when P/E looks infinite but the business is generating cash). The Piotroski F-Score reveals whether management is playing the cycle well — reducing debt during booms, preserving cash during busts.

For the commodity side, the Timing axis is the most important signal on the page. A mining stock with a high value score and negative momentum is almost certainly a falling knife — commodity prices are still declining, and the "cheap" valuation will get cheaper. The combination you want is high value with recovering momentum, which suggests the commodity cycle has bottomed and fundamentals are turning.

Specialty materials companies require a different lens entirely. Their competitive advantages come from formulation expertise, customer switching costs, and distribution networks — advantages that the Buffett quality model captures well. These companies rarely look cheap on traditional value metrics, but their quality and momentum scores tend to be significantly more stable than their commodity-producing peers.
