"PhDs making 7 figures" You describing a fund like Rentec Medallion, the Dow does not beat the best quant funds and hedge funds, not even close. Historically what does the Dow return? Something like 5% above the risk free rate with much larger drawdowns compared to the return it gives.
Also historically Dow Jones has been way too slow removing the Dogs, throttling returns. Bet, right now, they'd want a do-over for CRM - about where it was when it was added in 2020, but cut in half from high hit last year.
CRM doesn't seem to fit in with the other stocks. MSFT doesn't either but at least it is a leader of its industry. They should have removed GE much earlier and left XOM in there. Since Feb 2020 CRM is down 20% and XOM is up 110%. I think DJ30 strength is the rise of the industrials & defensive stocks like health care & insurance. I believe minus the tech stocks in the DJ30 it is almost break even. MSFT -25% AAPL -18% INTC -44% CRM -47% CSCO -22% IBM +10% So I think the non-Tech DIA is down roughly 2%. Frankly I don't consider IBM to be a tech stock. Its more like Accenture or Price Waterhouse Coopers (aka PwC) -- consulting.
Healthcare stocks are great. Tons of sick, obese Americans. Lots of $ from employers coughing up $ to pay for it all. Insurance is a great business, especially health insurance. Jack up those rates annually way higher than inflation.
