You can buy a stock if you think it will be fine and has upside.

You can short a stock if you think it will decline or get wiped out by increased shares, bondholder takeover, or BK

But if you want to go long, spread the risk and buy an ETF which in turn spreads the risk against many stocks.

At the end of the day, I think more people are comfortable eating at home with food they selected, cleaned and prepared than food possibly contaminated in a restaurant, shared dining area, or delivery folks until this blows over.
