Marathon Petroleum (MPC)

The chart plots daily Reddit mentions of MPC over the 30 days to 20 October 2026: 29 in total, busiest on 19 October with 10, and 2 on the last day counted. The line is the daily close over the same window: $406 on 21 September, $474 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 75% bullish to 100% bullish over the 5 days that carried enough mentions to measure. 25 days either fell under the 5-mention floor or carried no bullish or bearish mention at all, and so carry no sentiment point.
