Green-to-Red Move

A green-to-red move is an intraday cross from positive to negative against the prior close — a stock that was up on the day loses the entire gain and goes red. It is the bearish mirror of red-to-green, and on gapped-up momentum names it is a primary short trigger: the cross confirms that everyone who bought the open is now underwater.

The logic is trapped longs. Everyone who bought the stock above the prior close is now underwater, and the green-to-red cross is often where their selling accelerates. On a failed gapper the sequence is mechanical: lose the opening price, lose VWAP, then lose the prior close — each level adding sellers.
