This chart in words
The chart plots daily Reddit mentions of CMCSA over the 30 days to 17 August 2026: 58 in total, busiest on 23 July with 7, and 1 on the last day counted. The line is the daily close over the same window: $23.77 on 19 July, $26.20 on 16 August. Of those days, 20 were trading sessions and the other 10 are hatched on the chart. On 8 of them no session took place, and the last close before it is carried forward rather than plotted; on 1 of them no session took place, and this window holds no earlier close to carry forward; 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 58% bullish to 90% bullish over the 17 days that carried enough mentions to measure. 11 days either fell under the 5-mention floor or carried no bullish or bearish mention at all, and so carry no sentiment point.
