Questions about 300506.SZ
What people ask.
Why is 300506.SZ on Broken Stocks?
300506.SZ qualifies for the Red List on decline depth. It is down -34.9% from its rolling 252-day high of 7.36 CNY, set on 2026-08-07 — 34d ago.
Is 300506.SZ a falling knife?
By the most common technical definition — a steep, recent breakdown from a fresh high — yes. 300506.SZ is down -34.9% from its 52-week high of 7.36 CNY, set 34d 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 — historically most attempts to bottom-pick continue lower before reversing. Broken Stocks flags the pattern; it does not recommend buying or selling.
Is 300506.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.

At 4.79 CNY, 300506.SZ sits 29.6% of the way from its 52-week low (3.71 CNY) to its 52-week high (7.36 CNY). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.
