Hi there,
Social distancing has noting to do with stocks going up and down. This is the nature of the game - the stock markets go up and down - there are bear and bull markets. No stock goes up in a straighline forever, they all have ups and downs. This is just standard.
That being said, when there is a pandemic, economic downturn, political uncertainty, etc. - the markets tend to be more volatile. So the magnitude of those ups and downs will be greater. When there are stable macro factors, then the volatility tends to be less pronounced.
Likewise, there are certain stocks that are just simply more volatile. You can judge this by looking at the company's beta which is a measure of volatility of that company against the overall market. Typically these are reflected over a period such as 36 month. A Beta of 1 is a sign that the company is more likely to track the market. Above one , it is likely to be more volatile. A beta under 1 is a sign that the stock has been less volatile than the market. A negative beta indicates inverse relation meaning that it does the opposite of the markets.
