Launched on 06/16/2006, the WisdomTree U.S. Dividend exFinancials ETF (DTN) is a smart beta exchange traded fund offering broad exposure to the Style Box - Large Cap Value category of the market.What Are Smart Beta ETFs?Market cap weighted indexes were created to reflect the market, or a specific segment of the market, and the ETF industry has traditionally been dominated by products based on this strategy.Investors who believe in market efficiency should consider market cap indexes, as they replicate market returns in a low-cost, convenient, and transparent way.But, there are some investors who would rather invest in smart beta funds; these funds track non-cap weighted strategies, and are a strong option for those who prefer choosing great stocks in order to beat the market.By attempting to pick stocks that have a better chance of risk-return performance, non-cap weighted indexes are based on certain fundamental characteristics, or a combination of such.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.Fund Sponsor & IndexDTN is managed by Wisdomtree, and this fund has amassed over $548.05 million, which makes it one of the average sized ETFs in the Style Box - Large Cap Value.
