During the past 6 years we have become accustomed to opening our account statements and seeing values continue to go up. This month, we will see a decline in market values with equity markets off about 4% and bond markets down 1% during August. With the dramatic movement in markets, it is useful to talk about why investors achieve higher rates of return over time by investing in equities.

Most investors think about volatility as market movement on a particular day. Portfolio managers think about volatility as measured by standard deviation – not just in a day but over whole periods of time. Standard deviation is the measure of the “spread” of data: the higher the spread, the higher the standard deviation, the higher the volatility and the risk. The standard deviation defines the risk that we can expect during a given time. For instance, a treasury bill has a known return and maturity date so the price moves very little and correspondingly has very little volatility (or risk). On the opposite end of the spectrum, a small cap equity has no certainty of any return and could have high volatility. In general, we can expect that the greater the uncertainty of the investment, the higher the volatility.

Now here is the key insight: if all we wanted was low volatility, our only option would be to invest in treasury bills, achieving a return of close to zero. If we want a return greater than treasury bills, however, we have to be prepared to assume a greater degree of volatility. Essentially, higher volatility is the price you pay for potentially higher returns.

To understand volatility in returns, consider the case where you have two investments: Investment A has a return of 1% and risk of 1 and Investment B has a return of 10% and a volatility of 5. How to invest becomes a function of how much risk are you willing to tolerate. Over time the second investment would generate a higher rate of return but the price would vary greatly from day to day. By being willing to assume the higher price volatility you can achieve a higher rate of return which illustrates why equity markets have outperformed treasury bills over time.

At Toron AMI we spend as much time on risk as we do on expected returns. We try to make sure that any one event does not unduly impact the portfolio and that the companies in which we invest have the financial strength to thrive in a weak economic environment. By employing a disciplined portfolio construction process, we have been able to reduce the volatility of our portfolios without sacrificing performance.

In today’s volatile markets, some companies on our watch list have dropped to levels where they offer compelling value. We will use this market volatility to purchase those companies and add to any underweight positions. Volatility can be your ally if you take advantage of it.
