Best And Worst ETFs By 3-Year Net Capture Ratios

 | Jul 11, 2014 01:08AM ET

Attractive funds have higher upside capture ratios than downside capture ratios, which are measures of participation in monthly up and down periods of the fund versus its primary benchmark index.

Upside and downside capture ratios are a complement to other risk/reward measures such as the Sharpe Ratio and the Sortino Ratio. All such measures are retrospective and are not alone sufficient for the necessary forward view of an prospective investment or existing holding, but they should be considered in the total data mix.

Here is a look at the best and worst ETFs for net capture ratio (upside ratio minus downside ratio) for those ETFs that have at least $100 million in assets and 10 years of history. The 10 year history filter was to attempt to eliminate possible effects of new funds outperforming older funds due to smaller size. As funds increase in size they are forced to become more like their benchmark in composition, moving toward a zero net capture ratio.
