Benner’s approach was empirical, grounded in price data from 1780 to 1872, and used to extend projections far into the future by emphasizing recurring cycles in commodity prices and business activity. He treated these cycles not merely as descriptive patterns but as prescriptive guidance, advising investors on when to buy during "hard times" and when to sell during "good times."
Benner's time-price model identified nested peaks and troughs in commodity prices, agricultural yields, and broader economic conditions. Central to his framework were the following patterns:
■ 11-Year Cycle in Corn and Hog Prices: Beginning in 1836, this cycle alternated between 5- and 6-year sub-periods, reflecting fluctuations in agricultural staples. Benner broke it into peaks and troughs that aligned with seasonal and weather-related disruptions.
■ Business Cycle with 16-18-20 Year Peaks: Extending his commodity analysis, Benner described a broader 11-year business rhythm, characterized by peaks spaced 16, 18, and 20 years apart. Lows coincided with pig iron troughs, while panics occurred at intervals averaging 9 years (7-11-9 pattern, akin to the Juglar cycle). Every third peak aligned roughly every 54 years, echoing longer waves like those later formalized by Nikolai Kondratieff.
These cycles formed a hierarchical structure: shorter oscillations (5–11 years) drove immediate price swings, while longer ones (27 and 54 years) shaped multi-decade eras of prosperity or contraction. Benner integrated them into a single chart, forecasting "ups and downs" with directives such as "Years of Good Times: High Prices and the Time to Sell" for peaks and "Years of Hard Times: Low Prices and a Good Time to Buy" for troughs.
For 2025, Benner’s cycle predicted the US stock market driving higher; for 2026, it forecasts a major top: "High Prices and the Time to Sell Stocks and Values of All Kinds" into 2032 ("Years of Hard Times, Low Prices, and a Good Time to Buy Stocks"). 2026 is marked as a "B" phase year — a peak of high prices and euphoria, often the culmination of a bull market before a shift to downturns. Historical "B" peaks have aligned (often within 1-2 years) with major tops like: 1929 (Great Depression peak), 2000 (dot-com bubble), 2007 (pre-2008 crisis), and others.
Edward R. Dewey (1967) considered the true length of Benner’s pig iron price cycle to be 9.2 years and thus his "forecast got off the track by one year every five waves. By 1939 his projection was no longer usable." In 1971 Dewey commented: "Were Benner still alive and issuing yearly supplements to his Prophecies, he probably would have learned all that was necessary to know about cycles of fractional length and would have adjusted later forecasts accordingly."
