A smart beta exchange traded fund, the Invesco S&P 500 Equal Weight Consumer Staples ETF (RSPS) debuted on 11/01/2006, and offers broad exposure to the Consumer Staples ETFs category of the market.

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.

Investors who believe in market efficiency should consider market cap indexes, as they replicate market returns in a low-cost, convenient, and transparent way.

On the other hand, some investors who believe that it is possible to beat the market by superior stock selection opt to invest in another class of funds that track non-cap weighted strategies--popularly known as smart beta.

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.

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 managed by Invesco. RSPS has been able to amass assets over $304.66 million, making it one of the average sized ETFs in the Consumer Staples ETFs. This particular fund, before fees and expenses, seeks to match the performance of the S&P 500 EQL WEIGHT CONSUMER STAPLES INDX.

The S&P 500 Equal Weight Consumer Staples Index equally weights stocks in the consumer staples sector of the S&P 500 Index.

Cost & Other Expenses

Investors should also pay attention to an ETF's expense ratio. Lower cost products will produce better results than those with a higher cost, assuming all other metrics remain the same.

With on par with most peer products in the space, this ETF has annual operating expenses of 0.40%.

The fund has a 12-month trailing dividend yield of 2.24%.

Sector Exposure and Top Holdings

Most ETFs are very transparent products, and disclose their holdings on a daily basis. ETFs also offer diversified exposure, which minimizes single stock risk, though it's still important for investors to research a fund's holdings.

Representing 100% of the portfolio, the fund has heaviest allocation to the Consumer Staples sector.

Taking into account individual holdings, Lamb Weston Holdings Inc (LW) accounts for about 3.31% of the fund's total assets, followed by Philip Morris International Inc (PM) and Monster Beverage Corp (MNST).
