CNN has an article saying companies run by billionaires are better for investors, and I find it doesn’t make a strong case.
The second paragraph has a link on the word billionaire to an article that describes how Eric Tse inherited billions of dollars. Inheritance does not demonstrate competency.
Stock performance does not necessarily relate to anything about a billionaire. First off, billionaires like anyone else often are followers.
In my opinion there is nothing inherently good or bad about a billionaire.
