Here's how the prospectus described the Innovation Leaders All Cap fund's strategy:

The Fund employs a "passive management" investment strategy designed to track the performance of the IndexIQ(TM) Most Innovative Companies All Cap Index, an index of U.S. common stocks of companies that, regardless of capitalization, have been identified as the "most innovative" by the Index Administrators and therefore are included in the IndexIQ(TM) Most Innovative Companies All Cap Index. The components of this Index are derived using a purely quantitative, rules-based methodology. An "innovative" company is a company that demonstrates favorable results across multiple metrics related to corporate innovation, such as research & development spending and the value of its intellectual property. The IndexIQ(TM) Most Innovative Companies All Cap Index is typically comprised of 100 component securities of companies with market capitalizations of at least $300 million.

I guess that pretty much dashes our hopes of putting on an effective workforce/productively leaders arb.

Anyhoo.
