ETFs like VOO will buy it eventually.

It started me wondering if theres an ETF that explicitly avoids the top 20 companies

My gut instinct is that this would be a hugely underperforming investment strategy on both an absolute and risk adjusted basis. I would welcome empirical evidence contradicting my gut.

There's SPXT (S&P 500 excluding tech sector), +79% in 5y, vs full S&P +110% in 5y.

Obviously, in tech/AI bull market it can't be not underperforming.

I'd rather cross to international (including. US) than to that, for a less performing but more Black Swan proof fund.

Couldn't you set up some options to simulate that?
