This chart in words

The chart plots daily Reddit mentions of RNA over the 30 days to 9 September 2026: 15 in total, busiest on 19 August with 5, and 1 on the last day counted. The line is the daily close over the same window: $12.29 on 11 August, $11.35 on 8 September. Of those days, 20 were trading sessions and the other 10 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; 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.
