What the score is reading for CIEN
At the Friday 2 October close, CIEN scored 76, 11th of the 34 names here. The two inputs furthest above the board's median that session — not simply the largest, which is what separates CIEN from any other name that had a good day — were relative strength at +8.6 and trend at +9.5. Pulling the other way was drawdown at -4.5 — how far the price sits below its 52-week high.
Across the 16 sessions recorded since 3 September, CIEN has scored between 8 and 76, and that 76 sits near the top of that range. Net across the window it is up 68 points, and the largest single-session move was a rise of 36 points on 11 September.
