This chart in words

The chart plots daily Reddit mentions of RBRK over the 30 days to 30 September 2026: 10 in total, busiest on 3 September with 2, and 1 on the last day counted. The line is the daily close over the same window: $88.37 on 1 September, $113.04 on 28 September. Of those days, 19 were trading sessions and the other 11 are hatched on the chart.
