What counts as a falling knife in Healthcare?

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 14 Healthcare 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 Healthcare sector page?

The Healthcare sector page lists every Healthcare 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.
