The Janus Factor presents an innovative theory that describes how feedback loops determine market behavior. The book clearly shows how the theory can be applied to make trading more profitable. The metaphor of the two-faced god Janus is used to reflect alternating market environments, one dominated by trend followers and the other by contrarian bargain hunters.

In this book, author Gary Anderson puts forth a systematic view of how positive and negative feedback drive capital flows in the stock market and how those flows tend to favor either sector leaders or sector laggards at different times.

Intellectually challenging and highly practical, The Janus Factor offers insight into market behavior and new methods for capturing stock market trends.
