MKSI qualifies for the Red List on decline depth — down -37.0% from its rolling 252-day high. Past 30% with the high set inside the last four months — the recency clause that often precedes further breakdown. Depth plus recency: this is the pattern many investors call a falling knife.

Questions about MKSI

What people ask.

Why is MKSI on Broken Stocks?

MKSI qualifies for the Red List on decline depth. It is down -37.0% from its rolling 252-day high of $447.62, set on 2026-06-30 — 51d ago.

Is MKSI a falling knife?

By the most common technical definition — a steep, recent breakdown from a fresh high — yes. MKSI is down -37.0% from its 52-week high of $447.62, set 51d ago. That combination of depth (past the 30% Amber threshold) and recency (high set inside the last 120 days) is the textbook falling-knife pattern. Whether to try to catch it is a separate question — historically most attempts to bottom-pick continue lower before reversing. Broken Stocks flags the pattern; it does not recommend buying or selling.

Is MKSI 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 MKSI trading inside its 52-week range?

At $281.88, MKSI sits 13.4% of the way from its 52-week low ($256.16) to its 52-week high ($447.62). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.

How fast has MKSI been declining?

The current 37.0% decline accrued over 51d, which annualizes to roughly -264.8% 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.
