Designed to provide broad exposure to the Style Box - Mid Cap Value category of the market, the WisdomTree U.S. MidCap ETF (EZM) is a smart beta exchange traded fund launched on 02/23/2007.
What Are Smart Beta ETFs?
The ETF industry has long been dominated by products based on market cap weighted indexes, a strategy created to reflect the market or a particular market segment.
Market cap weighted indexes offer a low-cost, convenient, and transparent way of replicating market returns, and are a good option for investors who believe in market efficiency.
There are some investors, though, who think it's possible to beat the market with great stock selection; this group likely invests in another class of funds known as smart beta, which track non-cap weighted strategies.
Non-cap weighted indexes try to choose stocks that have a better chance of risk-return performance, which is based on specific fundamental characteristics, or a mix of other such characteristics.
The smart beta space gives investors many different choices, from equal-weighting, one of the simplest strategies, to more complicated ones like fundamental and volatility/momentum based weighting. However, not all of these methodologies have been able to deliver remarkable returns.
