FXAIX vs. VTSAX: How Do They Compare? (2023)

Can anyone tell me the difference between FXAIX and VTSAX besides the obvious one is Fidelity and one is Vanguard? My major question is why there is no minimum to invest into FXAIX but there is a required $2,500 to start in VTSAX?

Also the fees seem smaller in FXAIX yet the majority of books I’ve been reading tout VTSAX investing rather than individual stocks. What am I missing?

FXAIX is a better choice for investors who want to track the S&P 500, while VTSAX is better for investors who want to track the entire stock market.

Depends on your situation. For me, I use VTSAX, as well as small cap admiral in a Vanguard taxable account. But for my company 401k with Fidelity I hold some FXAIX. Lots of overlap but not the end of the world.

VTSAX is Vanguard’s Total Market Mutual Fund. The equivalent at Fidelity is not FXAIX but is FSKAX. The performance differences between VTSAX and FSKAX are really minor because they both just seek to mimic returns of the total stock market. If your brokerage is at Fidelity, just go with FSKAX.

The differences between VTSAX and FSKAX are so negligible you would never be able to tell.

VTSAX is more diversified and has slightly higher returns. If you’re going to choose between one or the other, VTSAX is the winner.

I have an account with Fidelity so to me FXAIX is less fees. Comparing their return, seems Fidelity is better in the 1, 3 and 5 year. They are almost exactly the same in the 10 yr.

If you already have a Vanguard account then just invest in VTSAX. It is the superior fund anyways. It would be silly to open a Fidelity account just to invest in the S&P 500 Index. Vanguard has that too, you know 🙂

Fidelity has zero expense funds. The comparable one to the Vanguard offering is FZROX. It also has some small and mid cap funds. Yes it’s completely free with no minimums.
