Questions about 002971.SZ
What people ask.
Why is 002971.SZ on Broken Stocks?
002971.SZ qualifies for the Red List on decline depth. It is down -45.9% from its rolling 252-day high of 78.88 CNY, set on 2026-07-03 — 77d ago.
Is 002971.SZ a falling knife?
By the most common technical definition — a steep, recent breakdown from a fresh high — yes. 002971.SZ is down -45.9% from its 52-week high of 78.88 CNY, set 77d ago. That combination of depth (past the 30% Amber threshold) and recency (high set inside the last 120 days) is the textbook falling-knife pattern. Whether to try to catch it is a separate question — the classification does not predict subsequent returns. Broken Stocks flags the pattern; it does not recommend buying or selling.
Is 002971.SZ a buy?
Broken Stocks does not issue buy or sell recommendations. The list is a rules-based technical warning system. It tracks structural decline depth and recency — not company quality, management, fundamentals, or news. Always do your own research and consult a licensed advisor.
Where is 002971.SZ trading inside its 52-week range?
At 42.68 CNY, 002971.SZ sits 24.5% of the way from its 52-week low (30.91 CNY) to its 52-week high (78.88 CNY). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.
How fast has 002971.SZ been declining?
The current 45.9% decline accrued over 77d, which annualizes to roughly -217.6% per year. Annualized pace is a sanity check — a 30% decline in three months is a different signal than a 30% decline over two years.
