Do SPY and IWM correlate?
SPY (SPDR S&P 500 ETF Trust) and IWM (iShares Russell 2000 ETF) are both exchange-traded funds (ETFs) that represent different segments of the U.S. stock market. While SPY tracks the performance of the S&P 500 index, which consists of large-cap stocks, IWM tracks the Russell 2000 index, comprising small-cap stocks. While there may be some correlation between the two ETFs due to overall market movements, their focus on different market segments means they can also exhibit divergent performance at times.
