The announcement didn't affect aftermarket trading significantly.
The stock market is completely disconnected from the election issue. It’s surprising, but on the other hand it’s good. In 2000 the market was following the drama.
Wall Street is now so dominated by the left wing, I suspect it has much to do with the fact that the left is convinced that they have nothing to worry about, they got this stolen election in the bag and will get to play all sorts of games with the treasury yet again. Hooray for helicopter money!
