Stock market performance during leap years

We get an extra day on the calendar this year (tomorrow), which got me wondering about whether leap years have had any correlation to stock market performance, Hope writes.

By the numbers: The average annual return of the S&P 500, including dividends, from 1928 to 2023 is 11.66%, according to an Axios analysis.

• Non-leap years, on average, performed slightly better at 11.76%, while leap years performed slightly worse at 11.35%.

The takeaway: There's not a significant difference, but it was fun to look through.
