business and investing

This is a superb investment book. Bernstein first covers basic statistical topics and historical risk and return data for stocks, bonds and bills. He then presents a lucid discussion of portfolio theory and its applications for the small investor. The most important result of this theory is that the risk and return of a portfolio are very different from the risk and return of its constituent parts, so that adding a 'risky' asset to a portfolio can actually decrease the portfolio's overall volatility. This discussion requires only minimal mathematical background. Bernstein then takes on the controversial topic of market efficiency. He also describes stock valuation models, current valuation levels, growth and value investing, Fama and French's three factor model, the concept of the efficient frontier and numerous other important topics in finance. But the discussion throughout is very clear and understandable as well as practical. After making a compelling case for index investing with periodic rebalancing, Bernstein presents helpful Vanguard and DFA model portfolios. What the author has done is to take the most significant results from academic finance and translated them into English for the individual investor. He has done investors a great service.

Dr. Bernstein's excellent presentation in this text of Modern Portfolio Theory (in particular, mean-variance analysis) and his three-step approach to asset allocation should not be overlooked by the serious investor or by investment advisors. While some background in statistics would be helpful to the reader, don't run away if you are not a mathmetician. Read the chapters slowly, one at a time, and you'll gain valuable insights into the all-important asset allocation decision. No other text I've read to date better explains Modern Portfolio Theory and the underlying theories of asset allocation to the lay investor.

Dr. B effectively presents additional arguments for value investing and tax-efficient investing. The last chapter also contains a very useful reading list, providing a synopsis of books by Malkeil, Bogle, Haugen, and a host of web sites which can provide valuable data and reading. Investors should not overlook Dr. Bernstein's own web site, which is frequently updated with his newsletters.

The very beginning investor should perhaps first explore Bogle's Common Sense on Mutual Funds, and then explore texts by Burton Malkeil, Larry Swedroe, and perhaps a few others. This text can then be dived into (patiently). Bruce Temkin's recent text, The Terrible Truth About Investing, should then follow, lest the individual investor believe that he or she knows it all.

I highly recommend this text as an addition to every serious individual investor's library, and to investment advisors desiring to explore the fundamentals of Modern Portfolio Theory.

Bernstein has become a guru to a peculiarly '90s group: well-educated, Internet-powered people intent on investing well-and with minimal 'help' from professional Wall Street
