Bull Market Just Completed Year 4. Will It Finish Year 5? Here's What History Says.

The S&P 500 bull market has entered its fifth year. Historical analysis shows that 5 of 6 bull markets lasting at least four years since 1957 reached their fifth birthdays, suggesting the current rally could continue. While rising interest rates and AI stock valuations pose potential headwinds, strong earnings growth expectations (27% annually over 5 years), reasonable valuations (forward P/E of 19.1), and potential for broader market participation support further upside.
