Questions about INSM
What people ask.
Why is INSM on Broken Stocks?
INSM qualifies for the Red List on decline depth. It is down -41.2% from its rolling 252-day high of $212.75, set on 2025-12-02 — 261d ago.
Is INSM a falling knife?
Not by the strict technical definition. INSM is down -41.2% from its 52-week high, but that high was set 261d ago — more than 120 days. A falling knife is usually a recent breakdown from a fresh high, not an established multi-quarter downtrend. INSM is still on the Red List for decline depth, but the freshness component of a falling knife is missing.
Is INSM 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 INSM trading inside its 52-week range?
At $125.09, INSM sits 28.4% of the way from its 52-week low ($90.39) to its 52-week high ($212.75). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.
How fast has INSM been declining?
The current 41.2% decline accrued over 261d, which annualizes to roughly -57.6% 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 INSM compare to its sector?
There are 143 other Healthcare tickers on Broken Stocks: 69 Red, 35 Amber, 39 Watch, with 50 showing recovering structural signals. Median sector decline is -36.1% — INSM's decline is deeper than the sector median.
Does INSM'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 (2026-08-06) is shown for reference only — listings can move tier between scans based on closing prices, regardless of fundamentals or news events.
