Have you checked the chart linked by OP? It has data for the same period of the last year and there’s no such drop so it disproves the seasonality thesis.

There could be something else of course. But also possible that some companies are being hit by energy crisis.

It may disprove it. Another possibility is COVID affecting the numbers from last year.

I'd like to see monthly numbers for at least a couple political cycles, or better yet for several stock market cycles.

The data seems to be really in a 365-day window, and on the 1st graph of the dashboard, the beginning and the end seem to be on the same level...
