Stocks vs. Bonds: Evaluating the Impact of 5% Treasury Yields

The recent rise in 10-year Treasury yields above 5% has led to a debate on whether stocks or bonds are a better investment. Historical data suggests that buying stocks when the 10-year Treasury yield is below 4% or above 8% has resulted in higher annualized real returns over the subsequent ten years. However, when the yield is around 5%, stock returns have historically been the least attractive. The cyclically adjusted price earnings ratio (CAPE) also indicates that stocks become expensive when long-term interest rates are high. On the other hand, bonds offer a nominal return of 5%, but the real return is much lower due to inflation. If investors trust historical data, long-term, good-quality corporate bonds or mortgage securities may offer higher probabilities of delivering better 10-year annualized real returns compared to stocks. However, past experience is not a guarantee of future returns.
