This ETF is linked to the S&P 500 Index, however its unique weighting methodology will make it useful for some, while impractical for active traders. Like many Rydex products, RSP is linked to an equal-weighted index, meaning that component companies receive approximately equal allocations. That results in exposure that is considerably more balanced than other alternatives such as SPY, and a methodology that some investors believe will add value over the long haul. In return for this unique exposure you can expect higher fees; this ETF is considerably more expensive and less liquid than both SPY and IVV, though it is still extremely cost efficient compared to most mutual funds.
