Questions about ZBIO
What people ask.
Why is ZBIO on Broken Stocks?
ZBIO qualifies for the Red List on decline depth. It is down -58.4% from its rolling 252-day high of $44.60, set on 2025-12-24 — 155d ago.
Is ZBIO a falling knife?
Not by the strict technical definition. ZBIO is down -58.4% from its 52-week high, but that high was set 155d ago — more than 120 days. A falling knife is usually a recent breakdown from a fresh high, not an established multi-quarter downtrend. ZBIO is still on the Red List for decline depth, but the freshness component of a falling knife is missing.
Is ZBIO 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 ZBIO trading inside its 52-week range?
At $18.56, ZBIO sits 27.8% of the way from its 52-week low ($8.51) to its 52-week high ($44.60). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.
How fast has ZBIO been declining?
The current 58.4% decline accrued over 155d, which annualizes to roughly -137.5% 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.
How does ZBIO compare to its sector?
There are 194 other Healthcare tickers on Broken Stocks: 88 Red, 47 Amber, 59 Watch, with 108 showing recovering structural signals. Median sector decline is -35.8% — ZBIO's decline is deeper than the sector median.
