Investors debate whether the record-high U.S. stock market valuations are justified or bear a warning. The S&P 500’s forward P/E ratio stands at 22.2, over 40% above its 40-year average. Factors like tech company profits and retirement fund buying could justify higher valuations, but caution remains due to potential disappointments.

Wall Street eyes 2026 with 14% profit growth expectations, dismissing significant recession risk.
