Where it sits in its two-week range
No chart for COST: the scanner recorded this window's prior two-week high of $925.13 but not the matching low, and a meter drawn against a guessed endpoint would misstate the one thing it exists to show.

What these mean
A cleared 2-week high row means COST traded above its highest price of the prior two weeks during that session; a lost 2-week low row is the mirror image. A range expansion row means the session's move was larger than 15% of the prior two-week range, which is a move that is big relative to how much COST had been moving. None of them forecast the next session.

Educational market data only. These are mechanical scanner observations about where a stock traded relative to its own recent range — not trade recommendations, forecasts, or advice, and not a claim that any of them work. A stock clearing a two-week high may keep running or reverse the same hour. Prices are captured when the scan runs and are not live quotes. Options involve substantial risk and can lose their entire value. Do your own research.
