Are rising interest rates, not risk fears, driving stock price moves?
Core argument: The equity risk premium fell from 5.94% on January 1, 2023 to 5.00% on July 1, 2023, then held relatively stable through the third quarter at 4.84% on October 1, 2023.
The equity risk premium declined in the first half of the year, from 5.94% on January 1, 2023, to 5.00% on July 1, 2023, but has been relatively stable in the third quarter, albeit on top of higher risk-free rates. Thus, the equity risk premium of 4.84% on October 1, 2023, when added to the ten-year T.Bond rate of 4.58% on that day yields an expected return on equity of 9.42%, up from 8.81% on July 1, 2023. Put simply, notwithstanding the ups and downs in stock prices and interest rates in the third quarter of 2023, there is little evidence that changes in the pricing of risk had much to do with the volatility. Much of the change in stock and corporate bond prices in the third quarter has come from rising interest rates, not a heightened fear factor.
