Why This Matters

The S&P 500's valuation has reached a level only seen once before, during the dot-com bubble, suggesting potential overvaluation and increased risk of a significant market correction.

This could also lead to a rotation out of growth stocks and into value or defensive sectors, impacting stocks like AAPL, TSLA, and AMZN.
