Marks discusses the various cycles that occur in the business world from economics and profit to credit and real estate. Marks' thesis is how the understanding of these cycles and their relationships effect investment returns. It is essential to know where the cycles stand at any point in time for long-term success in portfolio management.
Suppose a business man can sell some product for a dollar. Since the product is in high demand, it costs the businessman 97 cents to buy it to sell. The profit will be 3 cents per sale.
