The structural read

What price action says about DUO.

DUO qualifies for the Watch on decline sigma — the recent drop measures 4.2σ 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.

Questions about DUO

What people ask.

Why is DUO on Broken Stocks?

DUO qualifies for the Watch on decline sigma. The recent drop measures 4.2σ 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 (5.3%).

Is DUO a falling knife?

DUO 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 DUO 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 DUO trading inside its 52-week range?

At $1.34, DUO sits 47.9% of the way from its 52-week low ($1.01) to its 52-week high ($1.70). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.
