Adapted from a book by G. C. Selden published in 1912.

It examines the psychological background of stock market movements and how investors' emotions and behavioral patterns influence stock prices.

Main topics:

Mob psychology in the market: People tend to follow the crowd, which results in bubbles and panics.
Greed and fear: These two emotions are the primary drivers of stock market fluctuations.
News and speculation: News does not move the market by itself, but the mass reaction to it.
Market cycles: Due to human nature, markets follow repeating cycles.
The book is still relevant today, as the basic mechanisms of market psychology have not changed significantly in the past century.

Well-organized, searchable format, with pleasant background music.
