Questions about ASPN

What people ask.

Why is ASPN on Broken Stocks?

ASPN qualifies for the Amber List on decline depth. It is down -35.1% from its rolling 252-day high of $9.35, set on 2025-10-16 — 301d ago.

Is ASPN a falling knife?

Not by the strict technical definition. ASPN is down -35.1% from its 52-week high, but that high was set 301d 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 Amber 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 $6.07, ASPN sits 50.4% 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 35.1% decline accrued over 301d, which annualizes to roughly -42.6% 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 123 other Industrials tickers on Broken Stocks: 55 Red, 36 Amber, 32 Watch, with 30 showing recovering structural signals. Median sector decline is -32.6% — ASPN's decline is deeper than the sector median.

Does ASPN's earnings date affect its tier?

No. Tiering is decided purely by decline depth and recency of the rolling-high date. 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.
