Each subject in the text is dealt with from the standpoint of an individual "rational" investor who makes investment decisions under the efficient market conditions.

The chapters include solved problems key terms chapter-end questions and problems and a "Reality Check" section where problems with real data and investment environment are formulated. Moreover a list of suggested re adings a glossary an index and solutions to the chapter-end questions and problems are appended to maximize the benefits from the book.
