Over 25 years, the longest stretch both have prices for, the yearly figures are 10.1% for VTSAX and 9.9% for VFIAX.

The ride matters as much as the result. VTSAX's monthly returns swung about 15.4% a year, measured as annualized standard deviation, against 15.0% for VFIAX, so VFIAX has been the slightly calmer of the two. VTSAX's largest fall from a high was 50.8%, from October 2007 to February 2009. VFIAX's was 50.9%, from October 2007 to February 2009.

Both had their worst year in 2008, when VTSAX returned -37.0% and VFIAX returned -37.0%. Month to month, they moved almost in lockstep, with a correlation of 1.00. Holding both adds little variety, because they rise and fall together.

Buying a little each month narrows the gap from timing. Putting $100 a month into each for the last 10 years would have cost $12,000 and be worth about $25,549 in VTSAX and $26,423 in VFIAX. These results are historical and hypothetical, and past performance doesn't indicate future results. A fund spreads your money across its holdings, but it still falls when they fall, as the drops above show. See each on its own on our VTSAX calculator and VFIAX calculator.

Should I invest in both VTSAX and VFIAX?

It depends on how much they overlap. Their monthly returns have a correlation of 1.00, where 1 means they move exactly together. At that level, owning both is close to owning more of one, so it adds little spread. Check what each holds before splitting your money.

Are VTSAX and VFIAX the same kind of investment?

They're both mutual funds. Vanguard Total Stock Market Index Fund trades as VTSAX, and Vanguard 500 Index Fund trades as VFIAX. Their returns track each other closely, so they likely hold many of the same companies. Read each one's prospectus or annual report for fees and holdings, which we don't cover here.

Do these returns include dividends?

Yes. We use prices adjusted for splits and dividends, which assumes every dividend was reinvested. That matters most when one pays out more than the other, because a plain price chart would understate its return. Our figures leave out brokerage fees and the tax you'd owe on dividends in a regular account.

How are gains on VTSAX and VFIAX taxed?

In a taxable US account, you owe capital gains tax when you sell at a profit, at long-term rates of 0%, 15% or 20% if you held for more than a year. Dividends are usually taxed in the year you receive them. In a Roth IRA or 401(k), different rules apply. Check IRS guidance or ask a tax professional about your situation.
