Rydex S&P Equal Weight ETF (RSP) Proves a Valuable Complement to Traditional Cap-Weighted Portfolios

Five Years Ago, RSP Opened the Door for the Alternatively-Weighted Product Revolution by Assigning an Equal Weight to Each of the 500 Stocks Within the S&P 500®

ROCKVILLE, MD--(Marketwire - April 28, 2008) - The first ETF to move away from cap-weighting is proving that equal weight strategies have a place in traditional portfolios. Rydex S&P Equal Weight ETF (AMEX: RSP) was launched five years ago this month, and has since demonstrated the potential diversification benefits of alternatively-weighted strategies. As of April 25, 2008, RSP has outperformed the S&P 500 since inception, returning 13.86% versus the index's 10.90%. The fund has also shown better year-to-date returns than the S&P 500, outperforming the cap-weighted index by more than 100 basis points for the same time period.

"Although equal weighting tends to outperform over time, there are periods when a cap-weighted approach will do better, depending on market conditions," says Ed Lopez, director of ETF strategies at Rydex. "This underscores the complementary nature of a combined cap-weight/equal weight approach to investing."

RSP provides broad market exposure by tracking the S&P Equal Weight Index, which includes the same 500 stocks as the well-known S&P 500. Unlike the S&P 500, which is weighted by market capitalization, the S&P Equal Weight Index assigns an equal weight to each of the 500 stocks, eliminating the bias toward large-cap companies.

"From a diversification standpoint, equal weighting offers investors inherent rebalancing of gains, as well as increased exposure to smaller, more nimble stocks within the S&P 500," says Lopez. "We've seen financial professionals take advantage of RSP's equal weight methodology to help reduce single-stock risk and better diversify predominantly cap-weighted portfolios."

According to a new white paper by Standard & Poor's, the S&P Equal Weight Index pioneered the development of noncapitalization-weighted indices that cater to investors who question market efficiency. With the number of alternatively-weighted products on the rise, the simplicity of the equal weight methodology has resonated with investors who are looking for a straightforward approach to complement traditional cap-weighted portfolios. RSP has attracted approximately $1.3 billion in assets under management and remains one of Rydex's most popular ETFs.
