Charles H. Dow and the Dow Theory

Charles H. Dow and the Dow Theory combines a biography of Charles H. Dow with a critical examination of how his market observations developed into Dow Theory. George W. Bishop, Jr. traces Dow’s early newspaper career, financial journalism, and stock market writings before examining the contributions of S. A. Nelson, William Peter Hamilton, and Robert Rhea.

Originally prepared as a doctoral dissertation, the book uses documentary research and close analysis of published writings to distinguish Dow’s original ideas from later interpretations. Bishop examines the relationship between prices and underlying values, the classification of market movements, and the role of stock averages. He also compares treatments of confirmation, secondary reactions, volume, and trading ranges.

A central contribution is its explanation that the established Dow Theory represents an evolving synthesis rather than a single, unchanged doctrine authored by Dow. Bishop identifies differences and inconsistencies among its interpreters, including their treatment of chart formations and the independence of market averages from other information. The discussion also examines Dow’s broader principles concerning speculation, losses, overtrading, and security valuation.

For traders, investors, and researchers, the book provides historical grounding for evaluating classical trend analysis. Its substantial appendix reproduces Dow’s “Leadville Letters,” documenting his reporting on the Colorado mining boom and adding context to his development as a financial journalist.
