The Uncommon Average: Long-Term Context on Annual Returns
The Australian stock market has delivered an average annual return of around 13% since 1980. But short-term results may vary, and in any given period stock returns can be positive, negative, or flat. When setting expectations, it’s helpful to see the range of outcomes experienced by investors historically. For example, how often have the stock market’s annual returns actually aligned with its long-term average?
Exhibit 1 shows calendar year returns for the S&P/ASX 300 Index (Total Return) since 1980. The shaded band marks the historical average of 12.94%, plus or minus 2 percentage points. The S&P/ASX 300 Index had a return within this range in only four of the past 39 calendar years. In most years, the index’s return was outside of the range—often above or below by a wide margin—with no obvious pattern. For investors, the data highlight the importance of looking beyond average returns and being aware of the range of potential outcomes.

Tuning in to Different Frequencies
Despite the year-to-year volatility, investors can potentially increase their chances of having a positive outcome by maintaining a long-term focus. Exhibit 2 documents the historical frequency of positive returns over rolling periods of one, five, and 10 years in the Australian market. The data show that, while positive performance is never assured, investors’ odds improve over longer time horizons.

Conclusion
While some investors might find it easy to stay the course in years with above average returns, periods of disappointing results may test an investor’s faith in equity markets. Being aware of the range of potential outcomes can help investors remain disciplined, which in the long term can increase the odds of a successful investment experience. What can help investors endure the ups and downs? While there is no silver bullet, understanding how markets work and trusting market prices are good starting points. An asset allocation that aligns with personal risk tolerances and investment goals is also valuable. By thoughtfully considering these and other issues, investors may be better prepared to stay focused on their long-term goals during different market environments.
