What only one of them owns
Our book lists 476 positions for SPY that do not appear in our book for SIXG (78.0% of the fund), and 27 for SIXG that do not appear in SPY (47.1%).
Some of those will be the same company recorded under a different code in one of the two books, so the real difference in what you would own is no larger than this and may be smaller. We do not name the individual positions here for that reason.
