Q: Why is RARE on Broken Stocks?

RARE qualifies for the Red List on decline depth. It is down 45.1% from its rolling 252-day high of 42.37 set on 2025-07-09, 323 days ago. Tiering is rules-based and reflects price action only — not company quality, management, or fundamentals.

Q: Is RARE a falling knife?

Not by the strict technical definition. RARE is down 45.1% from its 52-week high, but that high was set 323 days ago — more than 120 days. A falling knife is usually a recent breakdown from a fresh high, not an established multi-quarter downtrend. RARE is still on the Red List for decline depth, but the freshness component of a falling knife is missing. Tiering is rules-based and reflects price action only — not company quality, management, or fundamentals.
