Assessing the Valuation of Vanguard S&P 500 ETF (VOO) After Its Recent Steady Gains

Simply Wall St · 09/24/2025 16:20

It seems like plenty of investors are keeping a close eye on Vanguard Index Funds, specifically the Vanguard S&P 500 ETF (VOO), these days, and for good reason. With no specific headline grabbing the spotlight, the subtle shifts in VOO’s performance might leave you wondering if we are looking at the start of a new trend or just a pause in what has already been an impressive run. The real question is what, if anything, these recent moves signal about the ETF’s underlying value—and if there is something investors might be missing.

Looking at the past year, VOO has steadily gained ground, with a total return of 17% and a year-to-date lift of nearly 14%. Over the last month, the fund’s value is up 3%, and momentum over the past 3 months has been solid, showing gains of almost 9%. That said, while there have been brief dips, like the minor loss in the last day, the bigger picture is clearly one of long-term growth and compounding returns. This pattern of slow and steady gains underscores why VOO is such a mainstay for both seasoned and newer investors looking for broad market exposure.

So with the ETF’s steady climb and valuation measures hinting at a potential discount, is now the moment to buy in, or are markets justifiably optimistic about further growth ahead?

Price-to-Earnings of 9.5x: Is it justified?

Based on its price-to-earnings (P/E) ratio, VOO appears undervalued relative to its industry peers. The ETF currently trades at 9.5 times earnings, while the US Capital Markets industry averages a much higher P/E of 27.2x.

The price-to-earnings multiple shows how much investors are willing to pay for each dollar of earnings. This is a widely used measure for valuing companies and funds, especially in the financial sector, because it provides a straightforward benchmark for comparing profitability and growth expectations across similar investments.

With a significantly lower P/E than its peers, the market may be underpricing VOO’s underlying earnings potential or considering other unique characteristics of the fund’s structure. This difference could signal an opportunity for investors who believe VOO’s long-term earnings power will be recognized.

Result: Fair Value of $942.26 (UNDERVALUED)
