What the score is reading for COHR
At the Monday 19 October close, COHR scored 17, 25th of the 34 names here. The two inputs furthest above the board's median that session — not simply the largest, which is what separates COHR from any other name that had a good day — were volatility at +1.7 and volume at +0.8. Pulling the other way was momentum at -11.9 — the day's move against the previous close.
Across the 15 sessions recorded since 21 September, COHR has scored between 12 and 83, and that 17 sits near the bottom of that range. Net across the window it is down 54 points, and the largest single-session move was a rise of 45 points on 1 October.
