In today's turbulent economic times, the need to re-examine market theory from the ground up is more critical than ever.While most investment books cover the importance of trends, this book actually gives you an understanding of the motion of trends and the influence of the larger market represented by the Dow Jones Industrials and Transports.These are a few memorable quotes from the book:"...the business community has a tendency to go from one extreme to the other. As a whole, it is either contracting business under a belief that prices will be lower or expanding under a belief that prices will be higher." "Speculation is not at its best a simple and easy road to wealth, but speculation through people who advertise guaranteed profits and who call for participation in blind pools is as certain a method of loss as could possibly be discovered.""When the market appears in a doubtful position it is sometimes wise to sell short a stock that is conspicuously above its value and buy a stock which is conspicuously below its value, believing that one will protect the other until the position of the general market becomes clear.""The best profits in the stock market are made by people who get long or short at extremes and stay for months or years before they take their profit."
