The structural read
What price action says about ATR.
ATR qualifies for the Red List on decline sigma — the recent drop measures 9.5σ 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.
Upstream TFC read: bearish alignment, current phase daily. Last bar types — daily 2U (red), weekly 2D (red), monthly 2D (red).
Questions about ATR
What people ask.
Why is ATR on Broken Stocks?
ATR qualifies for the Red List on decline sigma. The recent drop measures 9.5σ 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 (1.04%).
Is ATR a falling knife?
ATR 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 ATR 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 ATR trading inside its 52-week range?
At $124.84, ATR sits 42.9% of the way from its 52-week low ($113.77) to its 52-week high ($139.57). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.
