It is an uncertainty. Learn to differentiate between the two please.
Risk is measurable, like the odds of winning on any roll of a fair dice. Uncertainty is not measurable. It is and unknown unknown. Risk comes from not knowing what you are doing. Risk comes from focusing on the outcome (what will happen in the future) and not the process (what can I do now). Risk comes from acting like others are acting, and mindlessly.
In short, YOU are the biggest risk to your investments, not COVID.
lessons from history? Near pandemics or epidemics (like SARS or Ebola) are like natural disasters. All are gone this too will pass.
First, avoid rumour mongers, and avoid being one too – both on where the virus and the stock market is going. Two, avoid reading much of the news for it may trigger panic attacks. If the virus must come to you, it will come. You just practice safe health habits and keep your calm. Only that’s in your control. Nothing else is.
Stop worrying at all. This, too, shall pass. Not everything is so bad, and there is some good news –
5 billion people continue to live
More people are living healthier and longer
Most people’s standard of living continues to improve
