There is a chart that has come back into fashion among retail investors lately, and honestly, it’s interesting to see how a tool over 150 years old continues to generate so much debate. I’m talking about the Benner Cycle.

The history is fascinating. Back in 1875, a farmer named Samuel Benner suffered heavy losses during the 1873 crisis and decided to study agricultural price patterns. He observed that solar cycles seemed to impact crop productivity, which influenced prices. Based on this, he created a very simple market prophecy: lines marking years of panic, years of boom (good for selling), and years of recession (ideal for accumulating). Benner left a note on that chart: “Absolute certainty.” Almost two centuries later, it’s making a comeback.

The Benner Cycle became known for aligning with major financial events. The Great Depression of 1929, the dot-com bubble, the COVID-19 crash – the chart predicted small variations accurately. Many in the crypto community use this to support optimistic scenarios. The forecast suggested that 2023 would be an ideal time to buy, and 2026 would mark the next big peak. Some investors predicted that hype around crypto AI and emerging technology would intensify in 2024-2025 before a decline.

But here’s the problem: recently, things haven’t gone well. In April, global markets reacted severely to trade policy announcements. The crypto market dropped from $2.64 trillion to $2.32 trillion in a matter of hours. JPMorgan increased the likelihood of a global recession in 2025 to 60%, and Goldman Sachs raised its forecast to 45% in the coming months. Veteran trader Peter Brandt was quite direct: the Benner Cycle is more of a distraction than anything useful for those who actually trade.

Despite this, some still believe in it. The argument is that markets are not just numbers – they’re about sentiment, memory, and momentum. And sometimes, these old charts work not because they’re magical, but because many people believe in them. Searches for the Benner Cycle hit peaks in recent months, reflecting this demand for optimistic narratives in uncertain times.

The question is: will the Benner Cycle be right this time, or are we seeing proof that 19th-century tools have their limits in a completely different world?
