Questions about 300770.SZ
What people ask.
Why is 300770.SZ on Broken Stocks?
300770.SZ qualifies for the Amber List on decline depth. It is down -31.6% from its rolling 252-day high of 50.48 CNY, set on 2026-02-10 — 220d ago.
Is 300770.SZ a falling knife?
Not by the strict technical definition. 300770.SZ is down -31.6% from its 52-week high, but that high was set 220d ago — more than 120 days. A falling knife is usually a recent breakdown from a fresh high, not an established multi-quarter downtrend. 300770.SZ is still on the Amber List for decline depth, but the freshness component of a falling knife is missing.
Is 300770.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 300770.SZ trading inside its 52-week range?
At 34.55 CNY, 300770.SZ sits 49.8% of the way from its 52-week low (31.02 CNY) to its 52-week high (38.11 CNY). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.
How fast has 300770.SZ been declining?
The current 31.6% decline accrued over 220d, which annualizes to roughly -52.4% 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.
