COVID-19 is one of the biggest news right now in all countries (even those countries with no virus cases). Everyone is talking about this issue so you can't blame them if they think that the virus is one of the major factor that affects the price of the market. It's a world issue that everything is monitoring. It's not only the virus that causes the changes but other companies are also experiencing the decrease of the market.
For me, I do believe that Corona virus has a significant effect on the movement of the price.
