Rising Treasury Yields Lower S&P 500 Valuation Multiples

Rising U.S. Treasury yields are eroding stock valuation multiples, causing the S&P 500 multiple to drop from 22.2 times projected earnings at the start of the year to 19.3 times. The 10-year Treasury yield recently reached a 24-year high, which has increased the risk-free rate and reduced investor appetite for riskier assets.

Despite these headwinds, multitrillion-dollar tech companies including Nvidia, Microsoft, Apple, and Meta Platforms have driven the S&P 500 to record highs through strong earnings. This has resulted in market concentration reaching near all-time highs, as these few companies offset losses from the remaining 496 companies in the index.

Other industry groups, specifically banks and real estate, have declined during this period. Data from Citadel Securities indicates that higher interest rates continue to act as a headwind for equity markets, particularly for cyclical companies that are sensitive to economic shifts.
