What This Means
IWR is a mid-cap U.S. equity ETF from IShares, while XLC is a communication services ETF from SPDR. IWR and XLC do not own much of the same portfolio weight. That usually means you are combining different parts of the market, with only a small amount of duplication through names like WBD, EA, and TTWO.

What Drives The Overlap
