It started in Europe Coronavirus (more restrtictions, martial law, curfews, talk of lockdowns).
It then became very easy for the U.S. markets to follow because Coronavirus is raging in the United States too along with the fact there's still no Stimulus Deal.
Markets started declining about two weeks ago for those that only follow the charts will clearly see many more Down Gaps at the open than Up Gaps.
Those that want to know why / blame - Europe Coronavirus, U.S. Coronavirus, No Stimulus Deal a Trump / Biden is just a big pimple on what's going on in the World right now.
