Invesco S&P 500 Equal Weight Materials 

RSPM differentiates itself by using an equal-weighting strategy, which only includes basic materials companies in the S&P 500. Smaller companies have the same weighting as giants, tilting the whole fund to midcaps. Perhaps surprisingly, this does not increase RSPM's portfolio volatility. In short, investors who want to make a less-concentrated bet on the most liquid basic materials firms can do so with confidence in RSPM. The index is rebalanced on a quarterly basis. Prior to June 7, 2023, the fund traded under the ticker RTM.
