Choose a stock that is NOT down 90% or more over the past year.
While that eliminates many stocks on the Pink Sheets and OTC Markets, it is a great way to screen out losers. Any management that lets a stock totally fall apart once will likely do it again. And it does not matter if they have changed emphasis or not as far as what the company does, a loser stock is a loser stock if it is down that dramatically.
Exceptions: The Company or the shell of the Company is bought out by better people. Look at the people’s history in that case with other public companies.
