Dalbar in the US recently released their 21st annual study which continues to show just how poorly investors perform on average relative to market benchmarks over time and seeks to provide explanations for that underperformance. When in theory index investing is such as simple concept.
Before costs investing is a zero sum game, after costs it is a negative sum game. Investors are subject to the impact of taxes, trading costs and investment fees. Furthermore, there are complex technical issues to do with index reconstitution that affect the long term performance of an index tracking fund over time.
However, these factors do not fully account for the relative underperformance of investors over time. The key findings of the Dalbar study show that:
All investors need to be aware that overconfidence is an exceedingly common behavioural trait; most commentators tend to systematically overestimate their ability to accurately determine when markets are “high” or “low” compared to the evidence of their success. Levels of confidence are exacerbated during periods of persistently trending markets - upwards or downwards. Investors should watch out for making decisions when assets appear to be “obviously” over or under-valued – recent history tends to be a poor guide.
The conclusion reached by academics studying the subject is that those investors who have the benefit of working with an adviser are more objective and more disciplined than those investors who try to go it alone. In some studies investors achieve more than 100% of the returns of the funds in which they are invested by applying disciplined and objective portfolio rebalancing.

However, these factors do not fully account for the relative underperformance of investors over time. The key findings of the Dalbar study show that:
- In 2014, the average equity mutual fund investor underperformed the S&P 500 by a wide margin of 8.19%. The broader market return was more than double the average equity mutual fund investor’s return. (13.69% vs. 5.50%).
- In 2014, the average fixed income mutual fund investor underperformed the Barclays Aggregate Bond Index by a margin of 4.81%. The broader bond market returned over five times that of the average fixed income mutual fund investor.(5.97% vs. 1.16%).
- In 2014, the 20-year annualized S&P return was 9.85% while the 20-year annualized return for the average equity mutual fund investor was only 5.19%, a gap of 4.66%
