ETFdb recently carried an article about alternative weighting methodologies for ETFs. It’s a good primer to a few different ways in which some indexes are constructed differently from typical capitalization weighting. Some of the methods covered include equal weighting, dividend weighting, revenue weighting, and RAFI (fundamental) weighting. The article points out that no weighting method is a panacea and that all have pros and cons:
Ultimately, there is no universally superior weighting methodology that holds the secret to excess returns. Cap weighting will perform well in certain environments, while equal weighting will lead the way in others. The same can be said for all the other strategies out there; dividend-weighted ETFs enjoyed a banner 2011 as interest in stocks offering meaningful current returns surged.
The choice of weighting methodology is a very important one that has the potential to have a major impact on bottom line returns. But keep in mind that weighting methodologies essentially reflect a tilt towards one factor another, whether it be small cap stocks, value stocks, or leveraged stocks. There are environments in which each of those methodologies will perform well, and others in which they will struggle.
