TIL in 1933 the Wall Street Journal had a headline which read "Berlin Views Hitler Calmly: Rise in stocks reflects confidence he will not disrupt nation's affairs"
Events always seem more obvious and predictable after they have already taken place.
Here's a copy and paste from the 1933 article:
Rise in Stocks Reflects Confidence He Will Not Disrupt Nation's Affairs
Berlin is settling down to pass judgment on political developments. Politicians, economists and bankers declare there is usually wide discrepancy between the speeches of opposition politicians and the actions of the group when it gains power.
Consequently, it is not believed that Hitler will accomplish a change in the constitution or that [Reich Minister of Economics Alfred] Hugenberg will bring about a general reduction of interest rates. The government wants to obtain an adjournment of the Reichstag for several months, but it is questionable whether the Centre [Party] will approve of such action.
People will make parallels with Hitler's election and of Trump's, but I never heard anyone say Trump will keep the status quo (i.e. the constitution) to save stocks.
