From Vanguard forecasts lower long-term returns for S&P 500

How could Vanguard's forecast of lower returns affect the Voo ETF?

Possible What happens if… A possibility worth considering, not a forecast.

Voo may face tempered investor interest following Vanguard's lower return forecast. Vanguard forecasts that average U.S. stock returns will be only 4% to 5% annually over the next five to 10 years. This contrasts sharply with the S&P 500's annualized return of 15.11% over the past decade (2016 to mid-July 2026). Since Voo is an S&P 500 ETF managed by Vanguard, this forecast could influence investor expectations and capital allocation decisions regarding the ETF, potentially leading to shifts in demand.

The facts so far

As reported. Each one links to where it comes from.

  • The S&P 500 returned an annualized 15.11% over the past 10 years (2016 to mid-July 2026).aol.com
  • Vanguard forecasts average U.S. stock returns of just 4% to 5% annually over the next five to 10 years.aol.com
  • The dim forecast is attributed to the high valuations assigned to large-cap technology stocks.aol.com

Why it matters

For Voo, which tracks the S&P 500, the forecast represents a shift in the expected growth trajectory of its underlying assets. While the ETF's current value is determined by the index, a widely publicized forecast of significantly lower future returns can influence investor sentiment and capital flows, potentially affecting trading volume and perceived value.

This forecast highlights the difference between historical market performance and future projections. The past decade was described as one of the best-performing stretches in market history, but Vanguard suggests that the next decade is not obligated to look like that one, prompting investors to reconsider long-term growth assumptions.

What we don't know yet

  • Will the market post another decade of extraordinary gains, defying Vanguard's expectations?
  • How will other major asset managers respond to Vanguard's lower-return scenario?

What would change this answer

The S&P 500 continues to show strong growth in the near termThis would challenge Vanguard's dim forecast and likely boost investor confidence in Voo.
Large-cap technology valuations drop significantlyThis would validate Vanguard's reasoning and reinforce the lower return outlook for Voo.
