The S&P 500 may no longer reflect overall U.S.
The S&P 500 has long been the go-to gauge for U.S. equity performance, but recent data suggests it no longer tracks the broader market as closely as before.

Investors may need to look at additional indices or sector-specific metrics to gauge market health accurately.
