The structural read
What price action says about DOV.
DOV qualifies for the Amber List on decline sigma — the recent drop measures 7.4σ 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.
Questions about DOV
What people ask.
Why is DOV on Broken Stocks?
DOV qualifies for the Amber List on decline sigma. The recent drop measures 7.4σ 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 (1.27%).
Is DOV a falling knife?
DOV 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 DOV 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 DOV trading inside its 52-week range?
At $189.05, DOV sits 5.7% of the way from its 52-week low ($186.33) to its 52-week high ($233.65). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.
