Questions about INSP

What people ask.

Why is INSP on Broken Stocks?

INSP qualifies for the Red List on decline depth. It is down -73.5% from its rolling 252-day high of $160.65, set on 2025-05-14 — 365d ago.

Is INSP a falling knife?

Not by the strict technical definition. INSP is down -73.5% 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. INSP is still on the Red List for decline depth, but the freshness component of a falling knife is missing.

Is INSP 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 INSP trading inside its 52-week range?

At $42.66, INSP sits 0.0% of the way from its 52-week low ($44.41) to its 52-week high ($161.88). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.

How fast has INSP been declining?

The current 73.5% decline accrued over 365d, which annualizes to roughly -73.5% 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 INSP compare to its sector?

There are 182 other Healthcare tickers on Broken Stocks: 92 Red, 43 Amber, 47 Watch, with 55 showing recovering structural signals. Median sector decline is -35.8% — INSP's decline is deeper than the sector median.

Does INSP'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 (2026-05-04) is shown for reference only — listings can move tier between scans based on closing prices, regardless of fundamentals or news events.
