As the exchange traded products industry adds to and evolves from traditional market capitalization-weighted offerings, issuers are increasingly using alternative indexing. The next wave of ETF evolution will come from creative index strategies, self indexing, active management and easy access to unique asset classes.

There are currently 416 enhanced index-based ETF strategies on the market with $195.2 billion in assets under management, and 91 actively managed ETFs with $16.5 billion in assets, according to XTF data. In contrast, there are 1,623 U.S.-listed ETFs with $1.88 trillion in assets.

The universe of ETFs is quickly expanding and more providers are launching smart-beta ETF strategies to accommodate the growing demand from retail and institutional investors. Some of the more popular alternative indexing styles include equal-weight, fundamentally weighted, factor-based and low-volatility ETF strategies.

“Managers who use these methods to create portfolios are, in effect, combining elements of active and passive investing by actively creating portfolios, which may then be passively or more actively managed on a day-to-day basis,” according to WisdomTree.

Non-market cap weighted ETFs attracted over 29% of U.S. ETF equity inflows in 2013, despite only making up 19% of the total ETF universe. Investors, notably institutional pensions, endowments, foundations and asset managers, were attracted to the ETF’s transparency, liquidity and ease of implementation for both tactical and strategic allocations.
