This chart in words
The chart plots daily Reddit mentions of XBI over the 30 days to 18 August 2026: 18 in total, busiest on 23 July with 4, and 1 on the last day counted. The line is the daily close over the same window: $151.37 on 20 July, $159.72 on 17 August. Of those days, 21 were trading sessions and the other 9 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 we hold no close at all, which is a gap in our own record rather than a closure we can prove.
The chart plots daily Reddit mentions of XBI over the 90 days to 18 August 2026: 50 in total, busiest on 17 June with 7, and 1 on the last day counted. The line is the daily close over the same window: $132.48 on 21 May, $159.72 on 17 August. Of those days, 60 were trading sessions and the other 30 are hatched on the chart. On 29 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 100% bullish to 100% bullish over the 13 days that carried enough mentions to measure. 70 days either fell under the 5-mention floor or carried no bullish or bearish mention at all, and so carry no sentiment point.
