What the score is reading for COHR
At the Friday 28 August close, COHR scored 24, 24th of the 34 names here, and only one input sat above the board's median for it: volume at +3.5. The other five were at or below where the typical name on this board was reading, so the score rested on that one component rather than on broad agreement between them. Pulling the other way was momentum at -11.7 — the day's move against the previous close.
Across the 20 sessions recorded since 30 July, COHR has scored between 14 and 85, and that 24 sits near the bottom of that range. Net across the window it is down 16 points, and the largest single-session move was a fall of 61 points on 18 August.

Common questions
Why can Coherent lag pure optical names?
A meaningful share of revenue comes from industrial and telecom markets that follow their own cycles, diluting the datacentre signal.
