Questions about 7666.HK
What people ask.
Why is 7666.HK on Broken Stocks?
7666.HK qualifies for the Red List on decline depth. It is down -42.0% from its rolling 252-day high of 29.98 HKD, set on 2026-05-13 — 128d ago.
Is 7666.HK a falling knife?
Not by the strict technical definition. 7666.HK is down -42.0% from its 52-week high, but that high was set 128d ago — more than 120 days. A falling knife is usually a recent breakdown from a fresh high, not an established multi-quarter downtrend. 7666.HK is still on the Red List for decline depth, but the freshness component of a falling knife is missing.
Is 7666.HK 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 7666.HK trading inside its 52-week range?
At 17.40 HKD, 7666.HK sits 38.7% of the way from its 52-week low (9.46 HKD) to its 52-week high (29.98 HKD). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.
How fast has 7666.HK been declining?
The current 42.0% decline accrued over 128d, which annualizes to roughly -119.8% 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.
