This chart in words
The chart plots daily Reddit mentions of CIEN over the 30 days to 15 September 2026: 30 in total, busiest on 3 September with 10, and 1 on the last day counted. The line is the daily close over the same window: $445.69 on 17 August, $321.74 on 14 September. Of those days, 20 were trading sessions and the other 10 are hatched on the chart. On 9 of them no session took place, and the last close before it is carried forward rather than plotted; on 1 of them we hold no close at all, which is a gap in our own record rather than a closure we can prove. Sentiment — the bullish share of the mentions that took a side, where the chart's dashed rule marks the 50% at which bullish and bearish are even — ran from 80% bullish to 93% bullish over the 6 days that carried enough mentions to measure. 19 days either fell under the 5-mention floor or carried no bullish or bearish mention at all, and so carry no sentiment point.
