This chart in words

The chart plots daily Reddit mentions of MRK over the 30 days to 22 August 2026: 54 in total, busiest on 19 August with 26, and 2 on the last day counted. The line is the daily close over the same window: $131.11 on 24 July, $152.56 on 22 August. Of those days, 21 were trading sessions and the other 9 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. 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 86% bullish to 100% bullish over the 7 days that carried enough mentions to measure. 23 days either fell under the 5-mention floor or carried no bullish or bearish mention at all, and so carry no sentiment point.
