The structural read
What price action says about MTZ.
MTZ qualifies for the Red List on decline sigma — the recent drop measures 8.2σ over a 20-bar window. Sigma scales the move by the stock's own typical daily volatility, so a small percentage drop in a normally-quiet name can land here when the bigger players miss it on a pure-percent threshold.
A confirmed bullish signal on one or more time frames earned the Recovering badge. The tier says how deep the damage is; Recovering says momentum may be turning. Not a buy signal.
Whether MTZ's turn is investable is ConvictionEdge's question, not ours.
Upstream TFC read: strong alignment, current phase weekly. Last bar types — daily 2U (green), weekly 3 (green), monthly 2D (green).
Questions about MTZ
What people ask.
Why is MTZ on Broken Stocks?
MTZ qualifies for the Red List on decline sigma. The recent drop measures 8.2σ over a 20-bar window — large enough that even a small percentage drop is structurally significant given the stock's typical day-to-day volatility (3.0%). It additionally carries a Recovering badge — see below.
What does the Recovering badge mean for MTZ?
Recovering means our proprietary engine has flagged a confirmed bullish structural signal on one or more time frames (moderate or strong time-frame continuity). It coexists with the decline tier — MTZ is still Red List because the rolling-252-day decline hasn't healed, but a bullish setup has formed inside that decline. The two readings answer different questions: the tier tells you how deep the damage is; the Recovering badge tells you whether momentum may be turning. It's not a buy recommendation.
Is MTZ a falling knife?
MTZ is on Broken Stocks for time-frame continuity or decline-sigma reasons rather than headline depth, so the falling-knife label doesn't cleanly apply. The phrase usually requires a meaningful percentage drop from a fresh high. See the structural break signals above for the axis that actually triggered the listing.
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 $240.41, MTZ sits 5.2% of the way from its 52-week low ($230.10) to its 52-week high ($429.68). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.
