This chart in words

The chart plots daily Reddit mentions of CENX over the 30 days to 5 October 2026: 2 in total, busiest on 8 September with 1, and 1 on the last day counted. Across this window the close ran between $35.62 on 2 October and $48 on 8 September. The line is the daily close over the same window: $48 on 8 September, $35.62 on 2 October. Of those days, 19 were trading sessions and the other 11 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 2 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.
