I recently came across a fascinating story about a farmer from Ohio, Samuel Benner, who in the 19th century lost almost everything due to an economic crisis. Instead of giving up, he began obsessively searching for patterns in the markets, analyzing data on pig, iron, and grain prices. And here’s the interesting part – he discovered something that still captures investors’ attention today.

Benner observed that markets move in predictable cycles. These are not random fluctuations, but rather rhythms with certain schedules. Peaks, where it’s best to sell high, troughs, where you can buy cheaply, and plateaus, where it’s best to wait. His Benner cycle suggested an boom every 8-9 years, serious crises every 16-18 years. This was groundbreaking thinking at a time when most considered markets to be completely chaotic.

Interestingly, when we apply this theory to modern data – especially the S&P 500 – it turns out that the Benner cycle fits surprisingly well with actual events. The Great Depression of the 1930s, the dot-com bubble burst at the turn of the millennium, the 2008 financial crisis – all seem to confirm his observations. Of course, the fit isn’t perfect, but the overall trend is strikingly accurate.

This isn’t about the Benner cycle being some crystal ball for predicting the future. Rather, it’s about the fact that markets do follow certain patterns that can be observed and analyzed. Modern analysts studying historical cycles in major indices find similar rhythms around key economic moments.

For us, investors, the lesson from Benner is simple but valuable. Market history repeats itself – not exactly, but in similar cycles. If you can spot a peak or a trough, you can make more informed decisions. History is a powerful teacher, and studying trends can provide clues about what might happen. Knowing that declines and rebounds occur in cycles allows for a more cautious and long-term approach to investing.

The Benner cycle theory, spanning over 150 years, still matters. Of course, no one can predict every fluctuation, but certain patterns do repeat. It won’t make you rich overnight, but it offers a better understanding of the dance between boom and crisis, which has historically followed a similar rhythm. This could be that extra perspective that helps navigate the world of investments.
