Just came across something interesting about market timing that's been circulating in trading circles lately. There's this old theory from Samuel Benner back in 1875 where he tried to map out economic cycles – basically arguing that markets follow predictable patterns of booms, recessions, and panics.

The core idea is pretty straightforward: if you can identify which period you're in, you'll know the right moments to act. According to Benner's model, there are roughly three distinct phases that repeat every 18-20 years or so.

First, there are the panic years – think 1927, 1945, 1965, 1981, 1999, 2019 and so on. These tend to be rough periods with market collapses and financial stress. The advice here is basically to sit tight and avoid panic selling, even though everything feels chaotic.

Then you've got the boom years where prices are climbing and markets are recovering strong. These are the periods when to make money by taking profits – 1928, 1935, 1943, and more recently 2007, 2016, 2020. These are historically when people successfully exited positions at higher valuations.

The third type is the recession phase – years like 1924, 1931, 1942, 1951, and more recently 2005, 2012, 2023. Prices are depressed, economic activity slows down, but here's where patient investors could potentially accumulate assets at lower prices, waiting for the next boom cycle to unfold.

So the overall thesis is: buy when things look bleak and cheap, hold through the panic, then sell when boom conditions return. It's a long-term perspective on market timing rather than day-to-day trading.

Now, important caveat – this isn't gospel. Markets today are influenced by way more variables than they were in Benner's era. Geopolitics, technological disruption, policy shifts, unforeseen crises – they all throw curveballs at historical patterns. But as a framework for thinking about longer-term cycles and the periods when to make meaningful moves? It's worth keeping in the back of your mind. Most traders probably underestimate how much macro cycles matter compared to individual stock picking.
