For investors, if there is one book you should read, it is "Four Pillars of Investing," by William Bernstein. "Four Pillars" is geared toward a general audience and explains four key investing concepts that every investor should be aware of. Prior to writing "Four Pillars," Dr. Bernstein wrote "The Intelligent Asset Allocator," but eventually realized this book fell short of his goals and then refined his ideas in developing the classic, "Four Pillars." While "The Intelligent Asset Allocator" remains on a lot of investing reading lists, in truth, it does not make for essential reading if you have already read "Four Pillars." Nonetheless, it does help to reinforce certain key ideas, which are valuable to keep in mind during rough bear markets like we are currently experiencing.
The key ideas reinforced in "The Intelligent Asset Allocator" include the following:
*Asset allocation is the only factor affecting your portfolio that you can actually control. Thus, it is the most important factor for investors to worry about – e.g., how much to invest in bonds versus stocks, how much to put into international stocks, etc.
*The essence of effective portfolio construction is the use of or a large number of poorly correlated assets. In other words, you want asset classes that move in opposite directions. For example, typically, when stock prices go down, bond prices go up. Also, foreign stocks and value stocks are not perfectly correlated with U.S. stocks, so during a bear market, owning these types of stocks may reduce risk.
*Foreign stocks belong in every investor’s portfolio. In his most basic model portfolio, Dr. Bernstein recommends investors own U.S. large stocks, U.S. small stocks, foreign stocks, and U.S. short-term bonds.
*Good companies are generally bad stocks, and bad companies are generally good stocks. Dr. Bernstein’s discussion of buying bad companies, or "value stocks," is the most persuasive of any investing book I have read in convincing me of the bonus of owning a mutual fund of "value stocks." Not only have their stocks outperformed "good companies’" stock, but there is also research supporting that these stocks are "less risky" in bear markets.
One other benefit of "The Intelligent Asset Allocator" is that it does get more specific than "Four Pillars" in terms of telling investors which mutual funds he recommends (most are with Vanguard) and also where these funds should be held (in taxable or non-taxable accounts). So, while this book is not essential reading, it is worth a read if you are looking for additional reading material to reassure you that you are on the right track during these trying times.
