My strategy is to look at the history of a company and determine if they'll make it after the pandemic ends.
Then I choose stocks whose prices have plunged, not ones that are doing well. It's risky but with higher risk, there's a chance of higher rewards.
Bamburi is one of them, DTB is another and it's still going down, Total because of worldwide oil prices. Once you buy, you have to be patient to wait out until the prices rise again. It could take up to a year or more.
