Some exchange traded funds (ETFs) are being rolled out based upon equal weight rather than market capitalization. XShares Advisors recently launched a set of REIT ETFs that are equal weighted, and Rydex also has done so in recent years with the Rydex S&P Equal Weight (RSP).

Market-cap weighting is the traditional method for the S&P 500, and most ETFs are still weighted in this way. Jesse Emspak for Investor’s Business Daily says with equal weighting, a 1% rise or fall in one security’s price has the same impact on the index’s performance as another. This is not the case for market cap-weighted indexes. Because all stocks do not perform the same, re-balancing is needed periodically to put the weightings back in sync. Equal-weighted indexes are likely to outperform when small stocks do better than larger ones. This also seems to work in favor for single sector exposure.
