Nationwide S&P 500 Index Fund 

This fund employs a passive investment strategy, commonly known as indexing, with the primary objective of closely mirroring the performance of the S&P 500 Index before the deduction of any fund-related expenses. The S&P 500 itself represents roughly 500 significant U.S. corporations spanning a wide array of sectors. It is worth noting that the fund's portfolio may not necessarily include every single security found in the S&P 500, nor will it strictly maintain the identical proportional weightings of the index components.
