This chart in words

The chart plots daily Reddit mentions of MKSI over the 30 days to 28 September 2026: 1 in total, busiest on 6 September with 1, and 1 on the last day counted. The line is the daily close over the same window: $256 on 31 August, $260.82 on 25 September. Of those days, 19 were trading sessions and the other 11 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 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.

Crowd sentiment on MKSI · 30d

n = 1 scored · Method

1 mention of MKSI was scored for sentiment in these 30 days, so that one reading IS the sample. A bullish or bearish share of it could only ever read 0% or 100%, which states the sample size and not the crowd — so none is drawn. The chart on this page applies the same 5-mention floor to every day it plots.
