Graded on the same five checks, from their own SEC filings.
Three ratings, each a percentile against the 17 companies we cover in Building Materials. Deliberately kept apart rather than blended into one score — cheap, rising and well-run are three different facts, and a single number would hide which one is which.

What management does with the money — scored on whatever the filings answer, never as a share of the total.
A description of where this company sits among its competitors, not a recommendation. Ratings updated Nov 14, 2026.
A blank price-to-earnings means a loss, not a missing figure — the ratio has no meaning when there are no earnings to divide by, and printing a negative one would make the least profitable company look the cheapest.
Grades are trailing twelve months from each company’s own SEC filings, so they move only when a company files. Every column is computed by the same code that graded Martin Marietta Materials, Inc. on the overview — nothing here comes from a data vendor’s own ratios.
Industry membership is not a judgement about how similar two businesses are. It groups companies by what they are classified as, which is a starting point for comparison rather than a claim that they compete.
