There are key differences: the Vanguard ETF owns shares of small companies, while its iShares counterpart does not. Market-cap weighted benchmarks like the Standard & Poor’s 500 work just great for most investors, but this configuration puts the biggest and often priciest stocks in the cockpit to drive performance. For instance, the Consumer Discretionary Select Sector SPDR ETF (XLY) has benefited mightily from a years-long surge in top holding Amazon.com (AMZN).
