I feel like using percentages would be more meaningful. The Dow Jones peaked at 381 just before crashing in 1929. So using absolute numbers can’t be compared because the entire DJ wasn’t worth the drops we are seeing today.
I in 1929 it lost~10-12% on its worst days
So far Trump is losing ~5% approx each day
It’s not exactly a stellar endorsement. I’m only saying that you are comparing things at today’s dollar value, when the value of currency changes over time.
This Wikipedia page shows that the worst days by percentage are not where we are yet.
However… Rank, President (AFFILIATION), date, DJ, Point loss, %loss

All republicans. I note that the biggest daily gains were also republicans but most of them are related to the big drops e.g a day, week or month later, so they basically tank the index then the index recovers some time later.
Amazon 1 year after launch: Unfortunately, the space needed for robots in the van means that the van has to return to base 5 times more often to reload with the actual packages and the extra weight of robots more than doubles the weight of the van being lugged around in the form of heavy robots. So that’s why we are having to charge more for delivery and why it is taking longer for you to get your packages. But at least we can pay fewer salaries.
