Here my 2cents
The S&P is too much concentrated in the top10 holding. Approx 30% is in the hands of 10 stocks, and I don't like it, considering they are mostly all in the same industry.
I own approx $600k in 50 stocks with a very grade of diversification, and considering they are dividend-oriented, they are also low beta, so I feel comfortable with it.
You can argue that I can buy a Dividend Stock ETF, like
$VIG,
$VYM, or
$VIGI. Still, in such a way, I will be forced to reinvest the dividends into the ETF itself, while I prefer to reinvest dividends on stocks in my portfolio that are underpriced at the moment.
My portfolio will NEVER outperform the S&P500 unless in a bear market, but it makes me comfortable.
Anyway, I also have around 200k on an ETF portfolio, so I am not against passive investment at all π
