The structural read

What price action says about MTZ.

MTZ qualifies for the Red List on decline depth — down -38.4% 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 MTZ

What people ask.

Why is MTZ on Broken Stocks?

MTZ qualifies for the Red List on decline depth. It is down -38.4% from its rolling 252-day high of $441.43, set on 2026-05-06 — 106d ago.

Is MTZ a falling knife?

By the most common technical definition — a steep, recent breakdown from a fresh high — yes. MTZ is down -38.4% from its 52-week high of $441.43, set 106d 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 MTZ 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 MTZ trading inside its 52-week range?

At $271.86, MTZ sits 39.7% of the way from its 52-week low ($160.08) to its 52-week high ($441.43). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.

How fast has MTZ been declining?

The current 38.4% decline accrued over 106d, which annualizes to roughly -132.2% 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 MTZ compare to its sector?

There are 151 other Industrials tickers on Broken Stocks: 66 Red, 42 Amber, 43 Watch, with 29 showing recovering structural signals. Median sector decline is -30.8% — MTZ's decline is deeper than the sector median.

Does MTZ'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 (2026-07-30) is shown for reference only — listings can move tier between scans based on closing prices, regardless of fundamentals or news events.
