I sometimes compare the S&P 500 ETF VOO to RSP - the equal-weight version of the S&P 500, where the Magnificent Seven only have a 7/500 = 1.4% weighting.
Using the ETF's for both, both of which include reinvested dividends
Use the Adjusted Close column to compare the November 25 value to the December 31, 2024 value, because that includes reinvested dividends. The regular Close column is just the price (no dividends or other distributions)
