I think you mean fiscal 2021, which is from April 2020 to March 2021. That may just be around 3-4 months of production after normalcy returns. Hence the impact may be too early and hence traders and investors may get hit by volatility.

However, if you are looking at calendar year 2021, then you have better prospects as a trader and as an investors. That is because volatility is likely to come down by next year and even growth will be more certain. This should work in your favour both as a trader and investor. The real good period for markets will be from the first quarter of fiscal 2022.
