The crowd was not of one mind about ICU — bearish mentions outran bullish on 4 of the 6 days in this window we could measure

This chart in words

The chart plots daily Reddit mentions of ICU over the 30 days to 12 September 2026: 21 in total, busiest on 27 August with 6, and 1 on the last day counted. The line is the daily close over the same window: $3.20 on 14 August, $2.99 on 12 September. Of those days, 20 were trading sessions and the other 10 are hatched on the chart. On 10 of them no session took place, and the last close before it is carried forward rather than plotted. 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 33% bullish to 75% bullish over the 6 days that carried enough mentions to measure. 22 days either fell under the 5-mention floor or carried no bullish or bearish mention at all, and so carry no sentiment point.
