This chart in words

The chart plots daily Reddit mentions of SER over the 30 days to 23 October 2026: 28 in total, busiest on 15 October with 4, and 1 on the last day counted. The line is the daily close over the same window: $2.14 on 24 September, $1.76 on 21 October. 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 2 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 83% bullish to 100% bullish over the 12 days that carried enough mentions to measure. 12 days either fell under the 5-mention floor or carried no bullish or bearish mention at all, and so carry no sentiment point.
