ETFs and Indexing: Beyond Market-Cap Weighting
August 18th 2010 at 1:00am by Tom Lydon
Exchange traded funds (ETFs) come in all different shapes, sizes and indexing strategies. While weighting by company size is one of the most commonly used methods, there are other indexing strategies worth a look, too.
Quantitative Indexing. “Smart indexing” ETFs are designed to outperform the broad market. Don Dion for The Street says that one of the most important strengths of quantitative index ETFs is the dynamic aspect of their portfolios. These ETFs tend to do well in markets that are consistently moving up or down. In choppy markets, though, they’re not as easy to pin down. [The Ins and Outs of Quant ETFs.]

Revenue Weighting. This indexing method uses company revenues to determine their weights within an index. Intuitively, weighting by revenue makes sense because bigger revenues usually mean bigger profits and better businesses. Further, market cap doesn’t always reflect a firm’s underlying business value–just look at what happened in the dot-com bubble.

- RevenueShares Small Cap ETF (NYSEArca: RWJ)
Equal Weighting. Equal weighting treats all companies equally, giving them an even share of the total weight of an ETF. Equal weighting makes sense in an environment in which large-caps and small-caps are doing well. Large-caps serve as economic bellwethers, small-caps outperform in recovery periods. But by weighting all holdings equally, a fund may miss out on true economic activity.
