I guess we'll see if it's really a sell-off, or if it was normal market volatility around an election.
I definitely hadn’t expected a big correction, and would expect the market recover and recoup the losses soon.
The global events of last few years created a lot of inflation, and the new money has to go somewhere. A large part of stock market gains are the new money disguised as growth.
Wiener processes aren't a completely terrible model for markets though.
