Investors poured more than $1 trillion into U.S. exchange-traded funds (ETFs) in the first half of 2026, putting the industry on track for a record-breaking year.
The trend reflects a growing preference for low-cost, market-tracking funds, ETF.com reported. Vanguard has been one of the biggest beneficiaries, attracting roughly $260 billion in net inflows by midyear and trailing only iShares among major providers.
Two Vanguard funds, the Total Stock Market ETF and the Total International Stock ETF, also ranked among the five most-bought ETFs in the industry, according to ETF.com data.
Beyond those two bestsellers, four Vanguard ETFs deserve a closer look. Each gives investors exposure to a different part of the global stock market, with annual fees of no more than 0.05%.
David Dierking, a Chartered Financial Analyst (CFA) and founder of ETF Focus, highlighted the same four funds in a column for The Motley Fool, pointing to their potential role in a portfolio built for long-term investing.

How each Vanguard ETF fits into a portfolio
The Vanguard Total Stock Market ETF (VTI) provides exposure to more than 3,500 U.S. stocks at an annual expense ratio of just 0.03%. The fund attracted $31.2 billion in net inflows through midyear, according to ETF.com, making it a popular choice for investors seeking broad, low-cost market exposure.
The Vanguard Dividend Appreciation ETF (VIG) focuses on companies that have increased their dividends for at least 10 consecutive years. As of October 2026, its top holdings included Microsoft at 4.67%, Apple at 4.50%, and Broadcom at 4.34%.
Dierking favors VIG for its focus on established companies with a history of dividend growth.
For investors seeking greater growth potential, the Vanguard Growth ETF (VUG) offers exposure to large-cap growth stocks. It delivered an annualized 10-year total return of 18.1% as of Oct. 2, 2026.
However, the fund also fell roughly a third from its peak during the 2022 market sell-off, illustrating the volatility that can accompany growth-focused investing, as Dierking noted.
The Vanguard Total International Stock ETF (VXUS) holds roughly 8,500 stocks across developed and emerging markets outside the United States. International equities have outperformed the S&P 500 since early 2025, while VXUS attracted $18.4 billion in net inflows through midyear, according to ETF.com.
Why low-cost index funds remain popular
The appeal of index investing is straightforward: Consistently beating the market is difficult, particularly over long periods. The S&P Dow Jones Indices SPIVA scorecard shows that most actively managed U.S. large-cap funds underperform their benchmarks over 15-year periods.
Lower fees and broad diversification give index funds an advantage by reducing costs and spreading risk across thousands of stocks.
Vanguard has built its franchise on exactly this logic, and the 2026 inflow data shows advisors still buying it.
Allison Bonds Mazza, head of U.S. Wealth at State Street Investment Management, told InvestmentNews in August 2026 that the building-block approach has held up through recent market volatility, with advisors leaning more heavily on broad passive exposure during uncertain stretches.
<strong>We aren’t seeing advisors move away from low-cost core allocations. If anything, periods of market uncertainty tend to reinforce the value of having a diversified core portfolio</strong>.
Actively managed large-cap alternatives typically charge 10 to 20 times as much for comparable coverage, a gap that compounds against investors over decades.
A 1% expense ratio versus 0.04% means an active fund must beat its benchmark by nearly a full percentage point every year just to break even against the Vanguard set, a hurdle most managers fail to clear over 15-year windows, according to data from SPIVA.
What Vanguard’s research says younger investors stand to gain
Research from Vanguard suggests that younger investors with long investment horizons may benefit from holding a larger share of stocks in their portfolios. With decades to invest, they have more time to pursue long-term growth, although stocks can experience significant losses along the way.
Todd Schlanger, senior investment strategist at Vanguard, explained that a traditional portfolio split between 60% stocks and 40% bonds may not be the right fit for everyone. In his view, investors in their 20s with investment horizons stretching 60 to 70 years could benefit from a higher allocation to equities.
“They would likely benefit from more equities to grow their portfolio over the long run,” Schlanger said.

For younger investors with a long investment horizon, international stocks can add another layer of diversification to a portfolio dominated by U.S. equities. VXUS provides that exposure at an annual expense ratio of just 0.05%, making it a relatively low-cost way to invest in overseas markets.
Dierking’s four-fund selection also reflects the different roles stocks can play in a portfolio: VTI provides broad U.S. market exposure, VUG emphasizes growth, VIG focuses on dividend growth, and VXUS adds international diversification.
Building a portfolio for the long term
Vanguard’s target-date funds illustrate how investment strategies can change as investors approach retirement, generally starting with greater stock exposure and gradually becoming more conservative over time.
Investors building their own portfolios with VTI, VIG, VUG, and VXUS can take a similar approach, adjusting their allocations to reflect their financial goals, time horizons, and tolerance for risk.
The four ETFs have an equal-weighted average expense ratio of approximately 0.04%, although actual portfolio costs depend on how much an investor allocates to each fund.
Portfolios built with multiple funds also need periodic review. “Whether it’s 60/40 or another asset allocation, rebalancing will help make sure your portfolio is consistent with your risk tolerance,” Schlanger said.
Ultimately, VTI, VIG, VUG, and VXUS offer complementary approaches to stock investing at relatively low cost. Understanding each fund’s role can help investors build a portfolio that balances broad market exposure, dividend growth, growth potential, and international diversification.
