Questions about ASPN
What people ask.
Why is ASPN on Broken Stocks?
ASPN qualifies for the Red List on decline depth. It is down -44.5% from its rolling 252-day high of $9.35, set on 2025-10-16 — 365d ago. It additionally carries a Recovering badge — see below.
What does the Recovering badge mean for ASPN?
Recovering means our proprietary engine has flagged a confirmed bullish structural signal on one or more time frames (moderate or strong time-frame continuity). It coexists with the decline tier — ASPN is still Red List because a price-structure rule still triggers, but a bullish setup has formed inside that decline. The two readings answer different questions: the tier reflects the most severe triggered rule; the Recovering badge tells you whether momentum may be turning. It's not a buy recommendation.
Is ASPN a falling knife?
Not by the strict technical definition. ASPN is down -44.5% from its 52-week high, but that high was set 365d ago — more than 120 days. A falling knife is usually a recent breakdown from a fresh high, not an established multi-quarter downtrend. ASPN is still on the Red List for decline depth, but the freshness component of a falling knife is missing.
Is ASPN 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 ASPN trading inside its 52-week range?
At $5.19, ASPN sits 38.6% of the way from its 52-week low ($2.30) to its 52-week high ($9.78). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.
How fast has ASPN been declining?
The current 44.5% decline accrued over 365d, which annualizes to roughly -44.5% 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 ASPN compare to its sector?
There are 628 other Industrials tickers on Broken Stocks: 396 Red, 148 Amber, 84 Watch, with 291 showing recovering structural signals. Median sector decline is -35.7% — ASPN's decline is deeper than the sector median.
Does ASPN'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 (2026-05-07) is shown for reference only — listings can move tier between scans based on closing prices, regardless of fundamentals or news events.
