Benner discovered an 11 year cycle in corn and hog prices with alternating peaks at 4 and 6 year intervals. He also discovered an 11 year cycle peak in cotton prices and a 27 year cycle in pig iron prices with lows every 11, 9 and 7 years and peaks in a sequential order of 8, 9 and 10 years. He described a 54 Year Panic Cycle which arose from panics every 16, 18, 20 years, with this series repeating every 54 years, or as he explains, “it takes panics 54 years in their order to make a revolution or to return to the same order”. His book is one of the first examples of the development of cycles and periodicity theory in financial and commodity markets and was very popular amongst bankers and business men of the late 1800’s. His cycles and numerical sequences were effective throughout the 20th century, and can still be found to be operative today, predicting financial prices. Theorists will notice the similarities between his 11 year cycle and the sunspot cycle also of 11 years, something which has even been studied in current times by the Federal Reserve. Whether Benner was knowledgeable about this direct influence or not, he did make a connection through the weather and climate, and was likely aware of the earlier work on sunspots by Herschel, Jevons and others.
Benner never fully explained the basis of his cycle theories, but did state: "The cause producing the periodicity and length of these cycles may be found in our solar system … It may be a meteorological fact that Jupiter is the ruling element in our price cycles of natural productions; while also it may be suggested that Saturn exerts an influence regulating the cycles in manufacture and trade." Further, Uranus and Neptune: "may send forth an electric influence affecting Jupiter, Saturn and, in turn, the Earth … When certain combinations are ascertained which produce one legitimate invariable manifestation from an analysis of the operations of the combined solar system, we may be enabled to discover the cause producing our price cycles, and the length of their duration."
Later the larger 54 year cycle was also discussed in detail by Russian economist Kondratiev in 1925. Edward R. Dewey, Director of the Foundation for the Study of Cycles, assessed Benner's pig iron price forecasts over a 60 year period. Remarkably, he regarded this cycle as showing a gain - loss ratio of 45 to 1, which was “the most notable forecast of prices in existence”.
Extending and updating Samuel Benner's cycles and correlating them with more recent US-stock market prices, pointed to the low in 2003, the high in 2010, and the minor crisis in 2011. This would then be followed by a rising stock market into 2018 and a depression in 2021.
