RWJ

RWJ is a rules-based small-cap U.S. equity ETF that holds the same 600 stocks as the S&P SmallCap 600, but changes the weights based on each company’s trailing four-quarter revenue (top-line sales). It rebalances quarterly and caps any single holding at 5%, aiming to shift exposure away from pure market-cap weighting and toward companies with bigger real-world sales.
