Our book lists 485 positions for VOO that do not appear in our book for FSLD (99.2% of the fund), and 229 for FSLD that do not appear in VOO (99.8%).
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.
