Robert Rhea's monograph "Dow Theory" has long become a century-old classic on Wall Street stock investment. Robert Rhea supplemented and developed Dow Theory on the basis of Charles Dow. He believed that the basic movement of the stock market is based on the objective laws of the development of natural economic movements. This is the basis of Dow Theory and the ideological basis of this book. The book "Dow Theory" has made a huge contribution to Dow Theory. It also shows that Dow Theory is not just the personal theory of Charles Dow, but the crystallization of the wisdom of many investors who continue to develop, improve and innovate.
