It is human nature to be comforted by the idea that the investments you are buying are highly rated. The problem is that when we buy a “Five-Star” fund, we blindly extrapolate that the star rating translates into superior future performance. In fact, nothing could be further from truth. The Burns Advisory Group’s recent research paper, Star Gazing: Five Star Funds Revisited, went back to 1999 to study the subsequent 10-year performance of Morningstar’s five-star funds. The results were enlightening.
Burns found that of the 248 funds rated Five-Star by Morningstar on December 31, 1999, only four were still receiving that rating a decade later. Of the original sample, 87 had ceased to exist. And of those still existing, all had been downgraded to an average of just under three stars. And if this was not bad enough, the average performance for the five-star funds over this 10-year period was worse than the average for all funds in all categories except international stocks.
So what should you consider in making an investment decision? Clearly, a Five Star rating is nothing more than a starting point. You need a more broad-based evaluation, focusing on factors within your control. You might ask:
- Are the risks being taken related to return?
- Are those risks targeted in a reliable, consistent way?
- How diversified is the fund?
- What are the costs of the fund, i.e., expense ratio and turnover?
- Does it make promises it can't keep?
- What is more important - individual judgment or clear processes?
- Are the underlying strategies driven by forecasts?
- Does the fund take account of costs and taxes in its decisions?
- Does the fund manager communicate in a clear and consistent way?
The bottom line is that we believe you should construct portfolios not around short-lived Five Star ratings, but based on the time-tested, enduring principles of asset allocation, broad diversification, passive management, and low costs.
Reaching for the stars today could mean you find yourself clutching at straws in the future.
