Questions about ISRG
What people ask.
Why is ISRG on Broken Stocks?
ISRG qualifies for the Amber List on decline depth. It is down -38.0% from its rolling 252-day high of $603.88, set on 2026-01-07 — 225d ago.
Is ISRG a falling knife?
Not by the strict technical definition. ISRG is down -38.0% from its 52-week high, but that high was set 225d ago — more than 120 days. A falling knife is usually a recent breakdown from a fresh high, not an established multi-quarter downtrend. ISRG is still on the Amber List for decline depth, but the freshness component of a falling knife is missing.
Is ISRG 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 ISRG trading inside its 52-week range?
At $374.48, ISRG sits 16.7% of the way from its 52-week low ($328.57) to its 52-week high ($603.88). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.
How fast has ISRG been declining?
The current 38.0% decline accrued over 225d, which annualizes to roughly -61.6% 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 ISRG compare to its sector?
There are 143 other Healthcare tickers on Broken Stocks: 70 Red, 34 Amber, 39 Watch, with 50 showing recovering structural signals. Median sector decline is -36.1% — ISRG's decline is deeper than the sector median.
Does ISRG'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 (2026-07-16) is shown for reference only — listings can move tier between scans based on closing prices, regardless of fundamentals or news events.
