What counts as a falling knife in Basic Materials?

On Broken Stocks, a classic falling knife is a stock down 30% or more from a 52-week high that was set inside the last 120 days — i.e. steep and recent. The 12 Basic Materials names on this page all clear that bar today. Slow-grinding declines from old peaks aren't included here.

How is this different from the full Basic Materials sector page?

The Basic Materials sector page lists every Basic Materials stock down 20%+ from a 52-week high regardless of when that high was set. This page narrows to the textbook falling-knife pattern: steeper depth (30%+) and a recent rolling 252-day high (within 120 days). The intent is different — broader decline screen vs. classic falling-knife screen.

Is being on this list a sell signal?

No. Broken Stocks is a structural-recognition system, not a trading signal service. Listings reflect price action only — not company quality, management, or fundamentals. Not financial advice.

Why "classic": steep depth (Amber threshold and above) + a fresh peak (within the 120-day window used in the Red List recency clause). Stocks that match only one of those — for example deep declines from a stale peak, or shallow declines from a recent peak — are excluded here. See the methodology for the full ruleset.
