A price return is not the return of a fund that pays its income out. The coupon or distribution never appears in the price, so the return rows carry no winner here. FXNAX currently yields 3.49% and IVV 1.06%.
Volatility and max drawdown are measured over the window both funds cover: Sep 27, 2021 to Sep 24, 2026 (5 years).

Structure and taxes
FXNAX is a mutual fund and IVV is an ETF. A mutual fund prices once a day at net asset value and may carry a purchase minimum. An ETF trades through the day at whatever the market pays for it.
In a taxable account the difference that usually matters is distributions. An ETF can meet redemptions in kind, so it rarely has to sell holdings and rarely passes a capital gain to the people who held it; a mutual fund that sells holdings to meet redemptions can distribute a realised gain at year end to everyone still in the fund, whether or not they sold anything themselves. In a tax-deferred account that difference largely disappears. Both are descriptions of how the two wrappers work, not a recommendation.
Tax-loss harvesting works on either wrapper.
Holdings Overlap
At least 0.2% of IVV's money is in holdings FXNAX also owns.
Stated as a floor: for FXNAX, our book for it covers 79.0% of that fund, so a holding it does not list is one we cannot count as shared. The real figure is this or higher.
We cannot see either book well enough to say how much of this pair is duplicated.
The two holdings books were reported 92 days apart, FXNAX as of May 31, 2026 and IVV as of Aug 31, 2026, so some of the difference between them is the time between the two reports rather than the funds.
2 positions in common, counted across the 5,235 positions we hold weights for in FXNAX and 490 in IVV, against full books of 10,442 and 508.
