Standard and Poor's Guide to the Perfect Portfolio : Five Steps to Allocate Your Assets and Ensure a Lifetime of Wealth

Michael Kaye, a portfolio officer at Standard and Poor's, cites studies that documented the importance of asset allocation over individual stock selection. He defined asset allocation as "the process of determining the optimal way to divide a broad range of categories of assets (stocks, bonds, cash, and others) in a way that suits your investment time horizon and risk tolerance" (p. 10).  To make this investment decision, he itemized 5 steps: "Step 1: Identify your goals and objectives; Step 2: Choose the specific asset classes in which to invest; Step 3: Determine what percentage of your total assets belongs in each asset class; Step 4: Decide which investment products to use; Step 5: Monitor the performance of your portfolio and adjust your asset mix if warranted" (p. 13).

Of the common types of asset allocation approaches, the buy and hold strategy becomes the default position. Because after the initial purchases the investor takes no action, transaction costs remain low and the asset allocation can veer far from its original makeup. A less familiar approach to the average investor but one that many unconsciously follow, insured asset allocation strategy, entails selling assets that reach the floor in value and buying more assets that appreciate. As Kaye states, "insured asset allocation assumes that your risk tolerance changes with your level of wealth. You have no tolerance for risk below the floor value and an increasing risk appetite above the floor value" (p. 12).

With strategic allocation, the investor decides what percentages he or she designates for each asset class and rebalances periodically to maintain those percentages. Only because of changing goals or events, does the investor change the percentages. This approach accrues greater transaction costs than buy and hold and, like buy and hold, favors a long-term strategy. Tactical allocation, more short-term oriented, opportunistic, and riskier than strategic allocation, results in a change of percentages based on market conditions. Transaction costs grow from the time taken to follow market trends and the increased costs to buy and sell.
