Yes, but that’s not what the comment I’m replying to said. There seems to be some pervasive belief that absolutely no one ever beats the S&P500 index in the long run, which is obviously nonsense.
There’s nothing magical about some committee-curated collection of 500 US-only equities which means it outperforms every other option ipso facto.
If you were talking about a normal person actively managing a portfolio I’d be more inclined to agree.
