AAM Viewpoints — The Bull Market Turns Three…Where it Ranks, and Can it Last?

Where it Ranks

Last week marked the three-year anniversary of the current bull market since the October 2022 lows. The S&P 500 has gained over 90% (total return) over the period; an impressive, annualized return of approximately 25%. To put that in perspective, looking at monthly returns over the last 30 years, the three-year period ending September 2025 ranks in the 91^st percentile.

The only periods to see similar, three-year annualized returns were during the bull run of the late 1990s, following the Great Financial Crisis, and following Covid.

Average Bull Market

Going back to 1950, the average bull market lasts about five years with an average gain of 191%. More specifically, looking at the last five bull market cycles the average gain jumps to 285% over seven years, suggesting modern bull markets have become longer and stronger than older historical comparisons.

Of course, no one knows when a bull market will end. However, the current cycle is relatively young in terms of both duration and magnitude compared to recent expansions.

Can It Last?

The bull market has pushed U.S. equities to record levels. The S&P 500 closed at a record high 57 times in 2024 and 33 times year-to-date. Ironically, this can become an impediment to portfolio returns as investors hesitate. Contrary to the popular notion of “buy low, sell high,” putting money to work when the market is at record highs has proven to be a productive strategy. Analysis from BofA Global Research shows higher returns one , two, and five years later when buying the S&P 500 at highs verse all other periods.

Momentum can be powerful. Historical returns suggest that during a bull market accompanied by record highs such as the current environment, a “buy high, sell higher” approach may be reasonable.

Conclusion

A quick moment of appreciation for one of the strongest three-year runs we have seen in the last 30 years. As we enter year four, there is precedent for the market to continue to advance when compared to bull market averages. Perhaps counterintuitively, buying the S&P 500 at the highs has increased forward returns. For those who believe they have missed the boat, or are uncertain of putting money to work with equities at record levels, Peter Lynch put it best: “Far more money has been lost by investors in preparing for corrections, or anticipating corrections, than has been lost in the corrections themselves.”
