Add up exposure across your holdings
The seven company weights add to 34.69% using the sponsor’s rounded figures. To estimate their share of your portfolio, multiply that figure by your allocation to the fund. If SPY made up 20% of a portfolio on that date, the seven companies would account for about 6.9% of the portfolio through SPY.
Repeat the calculation for any other funds you hold, using holdings from the same date. Add any shares you own directly. That makes it easier to see how much depends on a single company, especially when several funds carry it under different share classes.
Compare the investment cases behind the weights
