5 Technology falling knives.
Every Technology stock on this page is down 30% or more from a 52-week high that was set inside the last 120 days — the textbook steep-and-recent pattern. Names are tiered by decline depth, decline sigma, and time-frame continuity. For the broader cut of Technology stocks (anything 20%+ off any 52-week high, including slow grinders), see the full Technology sector page.

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.
