DIVERSIFYING THROUGH MUTUAL FUNDS
A broadly diversified portfolio should include a variety of investments in three asset classes, depending on the time horizon of your goal and your risk tolerance. But the benefits of diversification may be limited unless your portfolio also has wide exposure to various combinations of sub-asset classes. The challenge lies in achieving and maintaining this level of diversification throughout your portfolio and over time—a process that requires knowledge, research, and the time to continually monitor the balance of holdings as asset prices shift.
DIVERSIFICATION CAN IMPROVE RETURNS
This chart compares the performances of two portfolios—a basic 60% stock/40% bond portfolio and a more diversified 60/40 portfolio—from the start of April 2000 through the end of March 2013. The two portfolios are indexed to $100,000 at the start. Their asset allocations are listed in the chart. The outperformance of the more diversified portfolio over the entire time period—through two bear and two bull markets—was significant, with the more diversified portfolio delivering a total annualized return of 5.1% compared with 3.8% for the basic portfolio.
Note: The starting date of the beginning of April 2000 was chosen because it was the nearest whole month to the start of the first bear market since 1999. The indexes used for the more diversified portfolio include the Russell 1000 Index, the Russell 2000 Index, the MSCI EAFE Index, the MSCI EM Index, the Barclays U.S. Aggregate Bond Index, the Credit Suisse High Yield Index, the Barclays Global Aggregate ex-U.S. Dollar Bond Index, and the J.P. Morgan Emerging Markets Bond Index Global. The indexes used for the basic portfolio include the S&P 500 Index and the Barclays U.S. Aggregate Bond Index.

Mutual funds offer built-in diversification because they generally hold dozens to hundreds of investments aligned with a particular theme or goal. Teams of investment professionals that include portfolio managers and analysts make decisions seeking to optimize the balance of holdings within the fund. These decisions are based on thorough analysis of market conditions and security valuations that may not be apparent without research, accessibility, and expertise. Indeed, opportunities within financial markets may be contrary to the larger economic conditions in a holding's economic environment. In other words, a French or Italian company might offer an excellent investment opportunity despite economic challenges in its country or region. Investment teams decide how the holdings in the fund affect its overall balance.
KEEP YOUR PORTFOLIO BALANCED
To manage your overall investment portfolio on your own, look for sectors, geographic regions, and market capitalizations that are underrepresented in your portfolio. And be sure not to neglect diversification in the fixed income portion of your holdings. If you're underweight in one category, you have too much exposure to another. Correcting this imbalance is important because it lowers your exposure to sectors that have risen comparatively in value and increases your exposure to those that have declined—and that action helps you maintain a portfolio that is properly allocated and diversified. Not only can rebalancing lock in gains, it will keep you well positioned to balance market risks with growth potential.
