Ben Felix’s YouTube channel is one of the better investment-oriented channels on that service. Like a lot of good investment advice, a lot of what he says comes down to simply not doing dumb s— like trying to time the market, etc.
What pushes his channel above others is that he does a good job of simply and thoroughly explaining why a lot of the approaches that get people into trouble don’t work. For example, his video on Warren Buffett does an excellent job of explaining how and why active managers almost always fail to beat index funds.
