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

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.

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.

Based on specific fundamental characteristics, or a combination of such, these indexes attempt to pick stocks that have a better chance of risk-return performance.

Methodologies like equal-weighting, one of the simplest options out there, fundamental weighting, and volatility/momentum based weighting are all choices offered to investors in this space, but not all of them can deliver superior returns.

Fund Sponsor & Index

The fund is sponsored by Invesco. It has amassed assets over $412.1 million, making it one of the larger ETFs in the Energy ETFs. Before fees and expenses, RSPG seeks to match the performance of the S&P 500 EQUAL WEIGHT ENERGY PLUS INDEX .

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

Cost & Other Expenses

When considering an ETF's total return, expense ratios are an important factor. And, cheaper funds can significantly outperform their more expensive cousins in the long term if all other factors remain equal.

RSPG's 12-month trailing dividend yield is 2.50%.

Sector Exposure and Top Holdings
