Why is 301658.SZ on Broken Stocks?

Is 301658.SZ a falling knife?
Not by the strict technical definition. 301658.SZ is down -67.4% from its 52-week high, but that high was set 171d ago — more than 120 days. A falling knife is usually a recent breakdown from a fresh high, not an established multi-quarter downtrend. 301658.SZ is still on the Red List for decline depth, but the freshness component of a falling knife is missing.
Is 301658.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 21.77 CNY, 301658.SZ sits 0.0% of the way from its 52-week low (21.83 CNY) to its 52-week high (66.93 CNY). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.
