This chart in words

The chart plots daily Reddit mentions of ALNY over the 30 days to 19 October 2026: 5 in total, busiest on 29 September with 3, and 2 on the last day counted. The line is the daily close over the same window: $244 on 21 September, $232 on 16 October. Of those days, 20 were trading sessions and the other 10 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 no session took place, and this window holds no earlier close to carry forward; 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.
