I want to buy ETFs tracking the S&P 500, 400, and 600 and I've discovered multiple offerings (SPY and IVV and maybe others for the 500) of what in my mind, should be the same product.
Are the only differences in ETF that cover the same indexes the expense ratios charged by the bank issueing and the volume that each trades or are there other differences as well?
Are there any sites that ranks ETFs that cover the same indexes?
