Can You Really Profit from This 150-Year-Old Strategy of Periods When to Make Money?

There’s a curious artifact in financial history that still captivates traders and investors today: an ancient chart claiming to predict when you should buy, sell, or stay out of the market altogether. This mysterious theory, often called the “periods when to make money,” dates back to 19th-century America and promises something modern finance rarely delivers—a roadmap through market cycles. But here’s the real question: does it actually work?

The Story Behind Benner’s Economic Prophecy

The tale begins with Samuel Benner, an Ohio farmer and businessman who became convinced that markets moved in predictable patterns. In 1875, he published “Benner’s Prophecies of Future Ups and Downs in Prices,” laying out a theory that would intrigue market watchers for generations. Later analysts adapted his work, spreading the gospel that if you could just identify which “period” you were in, you could time the market perfectly.

Benner’s core insight was elegant: divide economic history into three repeating categories. According to his theory, certain years reliably bring panic and collapse, others bring abundance and opportunity, and still others bring hardship and bargains. If the pattern held true, you could theoretically profit by knowing where you stood in this cycle.

The Three Periods When to Make Money Explained

Benner’s framework splits decades into three distinct phases, each with its own profit strategy:

Panic Years represent the danger zone. Historical records suggest crises struck in 1927, 1945, 1965, 1981, 1999, and 2019 according to this theory. The prediction: significant price declines and portfolio destruction. Investors following this calendar would sell aggressively and move to cash.

Years of Prosperity signal the time to harvest profits. These periods (including 1926, 1946, 1953, 1962, 1972, 1980, 1989, 1999, 2007, 2016, and predictively 2026) represent peaks where “sell everything” becomes conventional wisdom. If Benner was right, we should be offloading assets right now.

Hard Times Years flip the script entirely. According to the chart, economic troughs occur in years like 1924, 1931, 1942, 1951, 1958, 1969, 1978, 1986, 1996, 2006, 2012, and 2023. These are when shrewd investors buy at rock-bottom prices and hold for the prosperity phase.

Why Does This Theory Still Matter?

Fast forward to 2026, and it’s remarkable how many traders still reference Benner’s categories or similar cyclical frameworks. The theory’s enduring appeal lies in its fundamental promise: chaos can be tamed by pattern recognition. In an uncertain world, the idea that markets move in predictable waves is deeply comforting. Yet comfort and accuracy are rarely the same thing.

The Reality Check: How Well Did These Periods Actually Predict?

This is where the theory faces its hardest test. Yes, 2023 had considerable market turbulence—fitting the “hard times” prediction. And 2019 did experience volatility. But markets are far more complex than a neat three-cycle framework. The 2008 financial crisis didn’t align neatly with Benner’s panic year of 2007. The dot-com bubble peaked in 2000, straddling his prosperity category. Brexit shocked markets in 2016, which he predicted as prosperous.

The uncomfortable truth: even when the theory occasionally lands near actual events, correlation is not causation. Economic downturns result from unpredictable combinations of geopolitical events, policy decisions, technological disruption, and global shocks. The pandemic of 2020, for instance, created unprecedented circumstances no 150-year-old chart could have foreseen.

Professional Skepticism and Modern Economics

Most contemporary economists and financial analysts dismiss market cycle prediction as an exercise in futility. The efficient market hypothesis suggests that if such patterns were real and knowable, sophisticated traders would have already exploited them into irrelevance. The fact that Benner’s chart remains debated rather than universally profitable speaks volumes.

Moreover, even if historical cycles existed, the claim that you can use them to time specific years faces a fundamental problem: external variables keep changing. Monetary policy, technology, international trade, corporate structure—the economy of 2026 bears little resemblance to 1875. Using a 150-year-old framework to predict 21st-century markets is like using a buggy manufacturer’s business model to understand aerospace companies.

What Investors Should Actually Take Away

The real value of studying historical frameworks like Benner’s “periods when to make money” isn’t prediction—it’s perspective. Markets do move in cycles, even if not on such neat schedules. Understanding that booms aren’t permanent and crashes don’t last forever can provide psychological resilience during volatility.

But attempting to actually use this chart to buy and sell? That’s where the danger lies. You’d likely miss the gains during unexpected prosperity years, sell at precisely the wrong moment, and succumb to overconfidence bias during your “hard times” buys. Behavioral finance shows repeatedly that active market timing costs more than it gains for most investors.

Instead, diversified, long-term strategies that ignore short-term cycle predictions tend to outperform chart-watching approaches. Dollar-cost averaging, rebalancing, and staying invested through the noise—these unglamorous tactics beat trying to time when to make money based on theories from the Gilded Age.

The periods when to make money? They’re less about predicting specific years and more about maintaining discipline across all market conditions.
