Inflation's Unprecedented Impact on the Stock Market in 2024

The Consumer Price Index (CPI) is on track for a significant deceleration in 2023, similar to 2009 and the early 1980s, which could trigger a big move in the stock market in 2024. Falling inflation is generally positive for the stock market as it boosts corporate profit margins, reduces prices for consumers, and prompts the Federal Reserve to lower interest rates. Historical data shows that when the CPI slowed by more than 4 percentage points in a single year, such as in 2009 and 1982, it led to significant gains in the stock market. With falling inflation and expectations of rate cuts in 2024, experts predict a potential multiyear bull market for the S&P 500.
