Questions about 002831.SZ
What people ask.
Why is 002831.SZ on Broken Stocks?
002831.SZ qualifies for the Red List on decline depth. It is down -39.1% from its rolling 252-day high of 46.19 CNY, set on 2026-05-21 — 120d ago.
Is 002831.SZ a falling knife?
By the most common technical definition — a steep, recent breakdown from a fresh high — yes. 002831.SZ is down -39.1% from its 52-week high of 46.19 CNY, set 120d 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 002831.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 002831.SZ trading inside its 52-week range?
At 28.12 CNY, 002831.SZ sits 16.8% of the way from its 52-week low (24.46 CNY) to its 52-week high (46.19 CNY). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.
How fast has 002831.SZ been declining?
The current 39.1% decline accrued over 120d, which annualizes to roughly -118.9% 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.
