Launched on 11/01/2006, the Invesco S&P 500 Equal Weight Energy ETF (RSPG Quick QuoteRSPG - Free Report) is a smart beta exchange traded fund offering broad exposure to the Energy ETFs 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.

Because market cap weighted indexes provide a low-cost, convenient, and transparent way of replicating market returns, they work well for investors who believe in market efficiency.

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.

Even though this space provides many choices to investors--think one of the simplest methodologies like equal-weighting and more complicated ones like fundamental and volatility/momentum based weighting--not all have been able to deliver first-rate results.

Fund Sponsor & Index

Because the fund has amassed over $624.72 million, this makes it one of the larger ETFs in the Energy ETFs. RSPG is managed by Invesco. RSPG seeks to match the performance of the S&P 500 EQUAL WEIGHT ENERGY PLUS INDEX before fees and expenses.

The S&P 500 Equal Weight Energy Plus Index equally weights stocks in the energy sector of the S&P 500 Index.

RSPG's 12-month trailing dividend yield is 1.84%.

ETFs offer diversified exposure and thus minimize single stock risk, but it is still important to delve into a fund's holdings before investing. Most ETFs are very transparent products and many disclose their holdings on a daily basis.
