US presidential election: what came after

The market here is the average of the US stocks we cover (over US$10B), equal-weighted, not the S&P 500 · 2 times in our prices (2018-05-02 to 2026-10-30) · measured from the next day's close (the news came after the market shut)

“Any window”: the middle result and the share that rose over every window of the same length since 2018-05-02, event or not.

Too few to summarise: we need 5 and our prices hold 2. Here is each one.
