>>21687237eh only nominally
if you adjust the CAPE values for their general upwards trend over time you get picrel
so there have been 4 times where it was more expensive (relatively speaking):
~1895-1905 (gilded age in general)
1929 stock bubble pre-great depression
2000 dotcom bubble
2021 post-covid stimmy bubble
still alarming, but not necessarily uncharted waters
