In 1875, an Ohio pig farmer named Samuel Benner sat down to figure out why he'd just lost everything. The Panic of 1873 had wiped out his farm along with a huge swath of the commodities market, and instead of walking away from the business entirely, he went the other direction — he started digging through decades of pig iron, hog, and corn prices, looking for a pattern in what had just ruined him. The book he published, with the wonderfully blunt title Benner's Prophecies of Future Ups and Downs in Prices, laid out a chart of repeating cycles: years to expect panics, years to sell, years to buy. His projections run all the way out to 2059.
Benner's own theory for why the cycle existed is stranger than the chart itself. He'd noticed an roughly 11-year rhythm in corn and hog prices and became convinced it tracked the 11-year solar cycle — the same sunspot cycle astronomers track today — on the reasoning that solar activity shifted weather, weather shifted crop yields, and crop yields shifted prices. That specific causal chain hasn't held up. The chart, oddly, kept getting passed around anyway.
The three rhythms running underneath it
Benner's model isn't one cycle — it's three, overlapping and running at different speeds:
- Panic years, on an irregular 16, 18, and 20-year rotation — his projected bottoms for full-blown financial crises.
- "Good Times" years, closer to every 8 to 10 years — his projected peaks, and the point at which he told readers to sell.
- "Hard Times" years, the trough between good-times peaks — his signal to buy and hold until the next one.
None of the three intervals is fixed. That irregularity is either the chart's biggest weakness or its most honest feature, depending on how you look at it — Benner wasn't claiming a metronome. He was claiming markets have moods that repeat on a rough schedule, the way weather has seasons without ever hitting the calendar on the nose.
Where it's actually landed
Graded strictly, on precision, Benner's chart mostly misses. Graded on "was the general neighborhood right," it gets uncomfortably close a few times in a row for something built on 19th-century pig prices.
His chart flags 1927 as a panic year. The real crash came two years later, in 1929, kicking off the Great Depression — close, not exact. It flags 2007 as a Good Times peak, and 2007 genuinely was the top of the market before the 2008 financial crisis hit. It flags 2019 as a panic year; the actual COVID crash arrived in March 2020, about a year later than the chart called it. Three swings, three near-misses, none of them bullseyes.
Flip a coin sixteen years apart on repeat for a century and a half and you'll land near a few real recessions eventually — recessions aren't exactly rare events. The uncomfortable part is how often "near" turns out to mean within a year.
Why this isn't actually as impressive as it sounds
There's a real statistical reason a chart like this can look eerily accurate without being useful, and it's not really about Benner at all: the U.S. economy has gone through a recession or bear market roughly once every four to ten years for most of the last two centuries, for reasons ranging from credit cycles to inventory gluts to plain old speculative excess. If you draw three separate repeating grids on top of that — one every 16 to 20 years, one every 8 to 10, one filling the gaps — you're going to land close to something almost by construction. That's not a knock on Benner's diligence. It's just what happens when a forecasting method throws enough lines at a target that gets hit fairly often anyway.
The more grounded objection is the one modern analysts actually make out loud: Benner built this on agricultural commodity prices in an economy with no central bank actively managing the business cycle. The Federal Reserve didn't exist until 1913, decades after Benner published. A model built entirely on 19th-century supply-and-demand rhythms has no mechanism for "the Fed cut rates to catch the fall" — which is arguably a big part of why 2019's projected panic showed up as a shaky pre-COVID wobble instead of a full crash, before an actual pandemic did the job the following year regardless of what any central bank wanted.
Nobody serious is rebalancing a portfolio because a pig farmer's sunspot theory says to. But a rough, three-part rhythm that keeps landing within a year of major turning points, across a century and a half of completely different economic regimes, is at least a strange enough coincidence to notice — filed next to the other things worth glancing at, never the thing doing the deciding.
