 Last month I published a short blog article concerning the difference between "risk" and "volatility." On the heels of a fairly volatile month in the markets - accentuated by political instability abroad and spiking oil prices - and looking ahead to the battle over the budget here at home, a more detailed exploration is warranted. Because all investments involve some amount of risk, it is important to consider how we think about risk in our portfolios. In general terms, most would agree that the two biggest risks investors face are inflation and market volatility. Since it would be extremely difficult to avoid both risks at the same time, an investor's time horizon becomes the determining factor: to the investor with a short horizon, portfolio stability is the most important objective, as market loss would be more damaging than inflation. To the younger investor, loss of purchasing power is a much more serious consideration, therefore investments focused on long term growth should be the primary focus. Digging a little deeper, there's also a degree of difference between risk capacity - the factual ability to withstand downside risk, and risk tolerance - the psychological willingness to withstand it. This is, admittedly, a fine distinction, but it is a critical one in planning the allocation of your investments. The strategy which your portfolio is built around needs to conform to your capacity to tolerate risk ("I am comfortable having 90% of my investments in stocks"), but it also needs to have a pattern of returns that will not lead you to abandon it because your willingness to tolerate risk is insufficient. ("The market is heading for a correction and I don't want 90% stocks any more.)1 This is particularly true during extreme market periods. It does no good to know that a 90% stock allocation will most likely outperform a 70% stock allocation over 40 years if you are likely to abandon the portfolio during a volatile market environment. You'll forgive me the digression into the arcane. Suffice to say that these considerations, esoteric though they may be, assume a central role in the construction of your portfolio, from the creation of your Investment Policy Statement to the eventual allocation of your assets. To the extent that you have a sense of peace (or at least acceptance) in the complexion of your portfolio, we can attribute this to a healthy understanding of the types of risk we face as investors, and how this understanding is eventually incorporated into the methodologies currently being used in the maintenance of your accounts. 1 Attributable to Robert Gibson, from Asset Allocation: Balancing Financial Risk, McGraw-Hill, 3rd edition, August 2000. |
