I view investing like mix martial arts. To get good, you need to take bits from everywhere to eventually create your own style. Value investing is just one art form. With top UFC fighters, most are well rounded and are exceptional in one-two things. Like Jon Jones with his length and wrestling, he's also good in other aspects of the game.
So just being good with value investing is not good enough nowadays, in the long run anyways. The game is competitive nowadays so we need to constantly learn from other styles to create our own.
Also, everyone peaks. Like in sports, there are people who figured out an inefficiency and make it to the top. Eventually, others figure it out. Like Conor McGregor with his striking. Other fighters learned if you make him tired then his edge goes away.
I think investing is like the same. Traditional value investing might still work, but long term its edge isn't so black and white. So it's up to us to add to the depths that is value investing.
