My point is that Trump took credit for the stock market rising,
And he had a point. Increase in capital spending, decreased unemployment in sectors across the board, and winning concessions from trade partners which occurred under Trump's watch, are all excellent reasons why the stock markets have been rising the past few months.
The most recent declines are all tied to a single event, the COVID outbreak and the expected financial impacts.
So, unless you maintain the President Trump invented the outbreak and is single-handedly coordinating the spread of the virus, you can't blame the downturn on The President.
