This chart in words

The chart plots daily Reddit mentions of RGEN over the 30 days to 19 October 2026: 2 in total, busiest on 7 October with 2, and 2 on the last day counted. Across this window the close ran between $164 on 8 October and $192 on 30 September. The line is the daily close over the same window: $192 on 30 September, $175 on 16 October. Of those days, 13 were trading sessions and the other 17 are hatched on the chart. On 6 of them no session took place, and the last close before it is carried forward rather than plotted; on 3 of them no session took place, and this window holds no earlier close to carry forward; on 8 of them we hold no close at all, which is a gap in our own record rather than a closure we can prove.
