The structural read

What price action says about MIRM.

MIRM qualifies for the Watch on decline sigma — the recent drop measures 2.4σ over a 5-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.

Questions about MIRM

What people ask.

Why is MIRM on Broken Stocks?

MIRM qualifies for the Watch on decline sigma. The recent drop measures 2.4σ over a 5-bar window — large enough that even a small percentage drop is structurally significant given the stock's typical day-to-day volatility (3.27%).

Is MIRM a falling knife?

MIRM 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 MIRM 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 MIRM trading inside its 52-week range?

At $111.39, MIRM sits 88.3% of the way from its 52-week low ($84.33) to its 52-week high ($114.99). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.
