The Power of Diversification Stock prices don’t all move in the same direction at the same time, so diversifying a portfolio helps control risk By Michael Rechenthin
espite what financial advisors say, perfect diversification doesn’t exist. Advisors might suggest a little big cap here, small cap there, international this and fixed income that. Then they wave a diversification wand and call upon the magic financial fairy to eliminate risk from the portfolio. All of this works well as long as the market keeps going up. When the market heads south, that fairy is nowhere to be found. Neither is that financial advisor. But investors who learn a few techniques can succeed no matter what direction the overall market takes. Real diversification doesn’t guarantee high rates of return—its purpose is to gain greater control of the risk in the portfolio through careful selection of uncorrelated products and the mechanical application of selling options. Diversification provides control of investments by treating them as a portfolio of correlated and uncorrelated positions.

Take a look at a chart showing a portfolio of stock indices (see “Four portfolio stock indices,” right). While they’re all moving in (mostly) the
same direction, a slight amount of diversification is gained because the indices contain a large number of stocks and different allocations of components. Thus, the investor is dealing with “unsystematic risks,” which are specific to a company, industry or sector and can be reduced through diversification. But one can do better.
