Just came across this fascinating historical chart from Samuel Benner back in 1875 – dude was basically trying to crack the code on when financial markets boom, crash, and recover. Pretty wild that someone over 150 years ago was mapping out periods when to make money by studying economic cycles.

So here's how it breaks down. There are these three distinct phases that keep repeating:

First, you've got the panic years – think 1927, 1945, 1965, 1981, 1999, 2019, and supposedly 2035 and 2053 coming up. Roughly every 18-20 years like clockwork. These are the years when everything goes sideways – financial crises, market collapses, total chaos. The smart move? Don't panic sell. Just sit tight and wait it out.

Then there's the boom phase. Markets are recovering hard, prices are climbing, everyone's feeling good. Years like 2000, 2007, 2016, 2020 fit here – and interestingly, 2026 is supposedly in this category too. This is when you actually want to be selling, taking profits, getting out while the getting's good.

And finally, recession years – 2005, 2012, 2023, 2032, 2040. Prices are dirt cheap, economy's struggling. This is the accumulation phase. Buy stocks, buy land, buy commodities. Hold and wait for the boom to come around again.

The whole theory is basically: periods when to make money are about timing the cycle, not fighting it. Buy low during recessions, sell high during booms, and don't get caught panic-selling when crashes happen.

Obviously this isn't gospel – markets are chaotic, influenced by politics, wars, tech breakthroughs, all kinds of unpredictable stuff. But as a long-term framework? It's actually pretty interesting to look at. Worth thinking about when you're planning your next moves.
