alt Hacker NewsWay outside of my area of expertise, but a quick search suggests that exact numbers probably depend on exactly how you define the question, but it would be broadly reasonable to say that the balance is about 50/50 +/-5%, and trending towards the passive side over time.
Would you agree with that?
Yes. But I’d caution to not conflating passive investing with indexing to a popular index. They sound similar. But most passive assets index to one of a variety of indices, many of them built in-house by various asset managers. (Vanguard, for example, is famous for doing this.)
