Making its debut on 04/19/2011, smart beta exchange traded fund First Trust Mid Cap Value AlphaDEX ETF (FNK) provides investors broad exposure to the Style Box - Mid Cap Value category of the market.

What Are Smart Beta ETFs?

For a long time now, the ETF industry has been flooded with products based on market capitalization weighted indexes, which are designed to represent the broader market or a particular market segment.

A good option for investors who believe in market efficiency, market cap weighted indexes offer a low-cost, convenient, and transparent way of replicating market returns.

If you're the kind of investor who would rather try and beat the market through good stock selection, then smart beta funds are your best choice; this fund class is known for tracking non-cap weighted strategies.

This kind of index follows this same mindset, as it attempts to pick stocks that have better chances of risk-return performance; non-cap weighted strategies base selection on certain fundamental characteristics, or a mix of such characteristics.

This area offers many different investment choices, such as simplest equal-weighting, fundamental weighting and volatility/momentum based weighting methodologies; however, not all of these strategies can deliver superior results.
