I looked into somehow hedging against the Mag 7 in my portfolio (which is otherwise almost entirely in an S&P 500 index fund), but it seemed surprisingly difficult for something that is probably quite widely desired.
Though maybe I'm just unsophisticated. And it feels a little hopeless because there's no telling how long the smoke and mirrors will continue working, and whenever it stops, undoubtedly the rest of the economy is going to suffer, too. Bleh.
Investments can never be identical for everyone, but in my case I switched my assets from an MSCI World to an MSCI World ex USA.
For the U.S. market portion I adopted a more complex strategy based on factor / smart-beta investing (making sure that none of the top holdings include AI-related companies).
I'm not completely divested but I'm buying some VFVA as my non-tech fund.
Top holdings are CVS, Verizon and FedEx all at 0.8%. Basically normal companies.
It's amazing how traditional companies have done in comparison to the top of the S&P500 (or really the top S&P10). So I feel the need to buy the other stuff in case the top S&P10 is a bubble.
$RSP is $SPY, but equal allocation across all 500 companies. So the top tech stocks are ~1.5% of your holding instead of ~20%.
