The structural read

What price action says about RIO.

RIO qualifies for the Amber List on decline sigma — the recent drop measures 7.9σ 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: weak alignment, current phase daily. Last bar types — daily 2U (green), weekly 2D (red), monthly 2D (red).

Questions about RIO

What people ask.

Why is RIO on Broken Stocks?

RIO qualifies for the Amber List on decline sigma. The recent drop measures 7.9σ 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 (2.02%).

Is RIO a falling knife?

RIO 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 RIO a buy?
