Market indices
A market index tracks the performance of a group of shares or other investments e.g. the S&P 500 index which tracks the performance of the largest 500 shares in America. They can be a useful barometer for the ‘health’ of an investment market as a whole but it is important to use them appropriately.
For example, you cannot meaningfully compare the performance of the S&P 500 index (100% shares) with a portfolio that consists only 40% of shares. Similarly if you are comparing a euro denominated portfolio with the US market which is denominated in dollars, then again this is not necessarily an appropriate comparison.
The downsides of using indices as a comparison are therefore addressed by the use of:
Peer group
A peer group allows you to compare investments that are similar in nature e.g. a specific class of investments or geographical region, and because you are comparing “like for like” it can be a more meaningful comparison tool.
Morningstar.com is a particularly useful tool in this respect and can guide investors with regard to an appropriate benchmark and peer group.
Quartile rankings
These are used to compare returns of investments in the same category over a period of time. Investments in the top 25% are assigned quartile rank 1, the next 25% quartile 2 etc.
They can be useful in tracking consistency – what is important is not the quartile ranking in any one period, but they allow you to track trends over multiple periods and time frames.
There is no one way, or right way, to compare performance and you will likely need to combine several measures to get a more accurate reflection of performance. Even more importantly, this should be done regularly to ensure you are doing all you can to achieve your financial goals. Finally, you should take into account the risk you are taking to achieve a set level of return, and this will be the focus of a future article.
