Questions about ACAD
What people ask.
Why is ACAD on Broken Stocks?
ACAD qualifies for the Red List on decline depth. It is down -38.2% from its rolling 252-day high of $30.96, set on 2026-08-19 — 58d ago.
Is ACAD a falling knife?
By the most common technical definition — a steep, recent breakdown from a fresh high — yes. ACAD is down -38.2% from its 52-week high of $30.96, set 58d ago. That combination of depth (past the 30% Amber threshold) and recency (high set inside the last 120 days) is the textbook falling-knife pattern. Whether to try to catch it is a separate question — the classification does not predict subsequent returns. Broken Stocks flags the pattern; it does not recommend buying or selling.
Is ACAD 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 ACAD trading inside its 52-week range?
At $19.12, ACAD sits 0.0% of the way from its 52-week low ($19.69) to its 52-week high ($30.96). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.
How fast has ACAD been declining?
The current 38.2% decline accrued over 58d, which annualizes to roughly -240.4% 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.
How does ACAD compare to its sector?
There are 408 other Healthcare tickers on Broken Stocks: 273 Red, 95 Amber, 40 Watch, with 178 showing recovering structural signals. Median sector decline is -37.5% — ACAD's decline is deeper than the sector median.
Does ACAD's earnings date affect its tier?
No. Tiering uses decline depth and recency, bearish time-frame structure, and decline sigma. The earnings date on file (2026-08-04) is shown for reference only — listings can move tier between scans based on closing prices, regardless of fundamentals or news events.
