Why Stocks Go Up and Down is an in depth introduction to stocks and bonds. It explains the basics of of financial statement analysis, cash flow generation, stock price valuation, and more. Commonly misunderstood terms such as capitalize, equity, and diluted earnings are explained clearly. Stock valuation methods including price/earnings ratio, price/cash flow ratio, and Enterprise Value / EBITDA are covered. The book is about fundamentals; it is not an investment system or how to make a million dollars in the market. The subtitle, The Book You Need To Understand Other Investment Books says it best. That subtitle is the result of comments received from readers over many years.
