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. Sentiment — the bullish share of the mentions that took a side, where the chart's dashed rule marks the 50% at which bullish and bearish are even — ran from 80% bullish to 93% bullish over the 6 days that carried enough mentions to measure. 9 days either fell under the 5-mention floor or carried no bullish or bearish mention at all, and so carry no sentiment point.
