Costco Wholesale (COST)

The chart plots daily Reddit mentions of COST over the 30 days to 20 October 2026: 405 in total, busiest on 24 September with 40, and 10 on the last day counted. Across this window the close ran between $896 on 24 September and $995.13 on 19 October. The line is the daily close over the same window: $898 on 21 September, $995.13 on 19 October. 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. 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 70% bullish to 92% bullish over the 30 days that carried enough mentions to measure.

The chart plots daily Reddit mentions of COST over the 90 days to 20 October 2026: 1,095 in total, busiest on 20 August with 48, and 10 on the last day counted. The line is the daily close over the same window: $924.83 on 23 July, $995.13 on 19 October. Of those days, 62 were trading sessions and the other 28 are hatched on the chart. On 27 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 69% bullish to 93% bullish over the 89 days that carried enough mentions to measure. 1 day either fell under the 5-mention floor or carried no bullish or bearish mention at all, and so carries no sentiment point.
