Risk & Reward
Risk is inextricably linked to reward. In general, though not always the case, greater potential for reward comes normally at the expense of greater risk of short term price variation. In order to achieve higher levels of return an investor must expose themselves to a greater risk of volatility in the short term. However, if measuring risk as not only the fluctuation in price, but also the risk of failing to meet performance/ return expectations, then the risk return trade-off takes on a different form.
Some investors may be willing to forgo long term returns in exchange for protection against short term price variation. So long as the investor is aware that long term returns are being traded –off in this way. Other investors are willing to accept short term price variation in exchange for the potential to generate better long terms returns. A proper assessment of a client’s risk preference, their risk tolerance and capacity to bear risk will determine where they stand in this trade-off.
Time Horizon
As an investor’s time horizon lengthens, the greatest risks are that: the investor’s assumed rate of return is not met and/or the value of the investment is eroded by inflation.
As you extend the time period over which you observe the returns of various asset classes, what you see is a reduction in the probability of negative real returns (i.e. after inflation).
As the holding period is extended, the probability of a negative return from equities diminishes. The Barclays Equity Gilt study (2013) shows that the probability of equities outperforming Gilts over a 10 year time period is 79%. The probability of outperforming cash over a 10 year time horizon is 90%.
