Is 688270.SS a falling knife?

Not by the strict technical definition. 688270.SS is down -66.3% from its 52-week high, but that high was set 227d ago — more than 120 days. A falling knife is usually a recent breakdown from a fresh high, not an established multi-quarter downtrend. 688270.SS is still on the Red List for decline depth, but the freshness component of a falling knife is missing.

Is 688270.SS 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 54.93 CNY, 688270.SS sits 12.4% of the way from its 52-week low (39.71 CNY) to its 52-week high (162.86 CNY). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.
