What Stands Out In This Comparison
What This Means
IWD is a U.S. value equity ETF from IShares, while QQQ is an equity ETF from Invesco. IWD and QQQ overlap enough to matter, but they still bring different exposures to a portfolio. The overlap is concentrated in holdings such as GOOGL, AMZN, and GOOG, which explains why the score lands at 20.79%.
How They Differ
IWD is a U.S. value equity ETF from IShares, while QQQ is an equity ETF from Invesco. Neither fund clearly dominates on breadth, so the practical difference is more about weighting, index construction, and cost. IWD and QQQ are priced very similarly on expense ratio.
What Drives The Overlap
The overlap is driven by a relatively small set of large shared positions. The top three shared holdings account for 26.61% of the score, which means the result is heavily influenced by the biggest common weights rather than a long tail of tiny positions.
When One May Fit Better
Because IWD and QQQ are closer in breadth, the better fit usually comes down to index methodology, issuer preference, and cost. IWD and QQQ are priced very similarly on expense ratio.
