“Intelligent” or “enhanced” index exchange traded funds that implement active investment styles instead of a market-cap index have become a popular draw, even outperforming traditional indices.

For instance, the Invesco PowerShares and Dorsey Wright ETFs built around the Dorsey Wright & Associates concept of relative strength – a momentum investing technique that singles out the strongest performers compared to the overall market – has been outperforming their broader peers.

We have previously looked at the outperformance of the PowerShares DWA Emerging Markets Technical Leaders Portfolio (NYSEArca: PIE) compared to the larger emerging market ETFs, like the iShares MSCI Emerging Markets Index Fund (NYSEArca: EEM), even as the emerging markets as a whole lags behind the U.S. markets.
