The Machinery of Wall Street

First published in 1917, The Machinery of Wall Street by George Charles Selden is a masterful exposition of the inner workings of America’s financial center at the dawn of the modern era. Written by a trained economist and observer of market behavior, this timeless classic pulls back the curtain on how speculation, capital flows, and market operations function as a unified “machine.”

Selden explains how money moves through the complex web of banks, brokers, and investors — and how human psychology acts as the hidden gear within the system. Through lucid narrative and empirical observation, he dissects the forces of greed and fear, the mechanisms of speculation and manipulation, and the moral hazards that arise when markets deviate from sound principles.

Far more than a historical curiosity, this book remains a critical resource for understanding market structure, leverage, and behavioral dynamics. Readers will see how the foundations of today’s trading and financial systems were laid more than a century ago — principles that still govern liquidity, volatility, and confidence on Wall Street today.
