Manch is right in absolute term about the impact.
Do you think coronavirus is 30-45 days impact or 3+ years impact?
You have seen 600+ points DOW with trump tweet and then next day it comes back ! Like that, they bring down the market in the name of coronavirus.
US stock market will forget about coronavirus after 30-45 days (and after correcting just 10%). Market makers bring down the market deliberately with some scapegoat reason. They (Market makers) make money during this swing. They are the creators of the swing and they know when it drops and when it stops !
People believe this, that is the issue. People also forget this after 30-45 days.
