Why Owning the Entire U.S. Stock Market Is More Accessible and Affordable Than Ever
Twenty years ago, a diversified slice of the U.S. stock market cost investors hundreds of dollars a year in fees, required a minimum balance, and often demanded phone calls or paper forms. Today, anyone with a smartphone can buy the entire U.S. market for as little as $3 on a $10,000 portfolio—no paperwork, no minimums, no gatekeepers. The democratization of broad market investing isn’t just a story of low fees. It’s the result of a relentless price war among asset managers, turbocharged by technology and consumer demand.
Fee compression has turned once-exclusive index funds into commodities. Vanguard’s Total Stock Market ETF (VTI), Schwab’s SCHB, and iShares’ ITOT all charge just 0.03% in annual fees. That’s a 90% drop from the average expense ratio in the early 2000s, when most index funds cost 0.3% or more. Meanwhile, robo-advisors like Betterment and Wealthfront have stripped away the human advisor premium, automating asset allocation and tax-loss harvesting for a fraction of the cost.
For the first time, the promise of “owning the market” is real for small investors, not just institutions. According to Yahoo Finance, total market ETFs now hold hundreds of billions in assets, with investor inflows surging as cost and convenience converged. This isn’t just a trend—it’s a structural shift in how Americans build wealth.
Key Data on U.S. Stock Market ETFs and Index Funds: Costs, Performance, and Growth
Total market ETFs have set new records for both assets and investor inflows. Vanguard’s VTI, the largest of its kind, controls over $350 billion in assets as of mid-2024. Schwab’s SCHB sits at $36 billion, while iShares’ ITOT manages $50 billion. All three charge a razor-thin 0.03% expense ratio, making them the cheapest way to own over 3,500 U.S. stocks in one trade.
Performance has tracked the S&P 500 closely: VTI returned an average of 12.2% annually over the past decade, while SCHB and ITOT lagged by less than 0.1% per year. That’s nearly double the returns of the average actively managed U.S. equity fund, which delivered 6.8% annualized after fees, according to Morningstar. The result: investors have dumped expensive mutual funds, pouring $95 billion into total market ETFs in 2023 alone.
Market share tells the story. In 2010, total market funds held just 5% of all U.S. equity assets. By 2024, that figure has surged to 22%, with most growth coming from retail investors. Fund launches have slowed, signaling maturity. Now, the fight is over incremental fee reductions and tech-enabled convenience, not product proliferation.
Diverse Investor Perspectives: Why Different Stakeholders Favor Broad Market Ownership
Retail investors see total market funds as a shortcut to diversification. The days of hand-picking sectors or chasing hot stocks are fading. Data from Fidelity shows that 64% of new brokerage accounts opened in 2023 included at least one broad-market ETF. For millennial and Gen Z investors, the appeal is clear: one ticker, instant diversification, and no guesswork.
Institutional investors aren’t just chasing simplicity. Pension funds and endowments use total market funds as a baseline exposure, layering on tactical bets or alternative assets for alpha. For example, CalPERS holds VTI as a core allocation, then overlays private equity and real estate for diversification. The liquidity and transparency of ETFs make them preferable to legacy index funds, especially when rebalancing millions in assets.
Financial advisors have shifted their tune. Ten years ago, many resisted passive investing, fearing loss of control. Now, 71% recommend total market funds as a default, according to Cerulli Associates. Their concerns are more nuanced: some warn of “overdiversification,” arguing that including thousands of microcap stocks dilutes returns. Others question whether broad-market ETFs can shield clients from sector blowups, pointing to the 2022 tech rout as evidence. Still, the cost-benefit equation overwhelmingly favors market-wide ownership for most portfolios.
How Today’s Market-Wide Investing Compares to Historical Approaches and Past Eras
Owning the full market wasn’t always this easy—or this cheap. In the 1980s and 1990s, most investors accessed stocks through actively managed mutual funds or sector-specific vehicles. Expense ratios routinely topped 1.5%, and performance lagged the market. The rise of the S&P 500 index fund in the late 1970s sparked a revolution, but “total market” funds didn’t hit the mainstream until the 2000s, when Vanguard launched VTSMX and later VTI.
Active managers claimed they could beat benchmarks, but the numbers didn’t back them up. Between 2004 and 2024, only 18% of U.S. equity managers outperformed the broad market after fees, according to S&P Dow Jones Indices. Meanwhile, total market funds mirrored index returns almost exactly, minus a sliver for expenses. The ETF boom of the 2010s accelerated adoption, slashing trading costs and minimums.
The shift from sector funds to total market exposure has changed portfolio construction. Instead of picking energy, tech, or financials, investors now own a slice of every sector—including thousands of small-cap and microcap stocks. The result: broader diversification, lower risk, and less reliance on manager skill. The historical lesson is clear: investors who embraced broad market funds captured more upside and fewer surprises.
What Owning the Entire U.S. Stock Market Means for Individual Investors’ Portfolios
Diversification is the headline benefit. Total market ETFs spread risk across more than 3,500 companies, insulating investors from single-stock blowups or sector implosions. When tech cratered in 2022, energy and utilities cushioned losses. The low expense ratios—often 0.03%—mean investors keep more of their returns, compounding wealth faster.
But broad market ownership isn’t a panacea. Investors are still exposed to systemic shocks: when the entire market tanks, so does the ETF. The lack of targeted exposure means investors miss out on outsized gains from surging sectors. For those seeking high-growth or defensive allocations, total market funds can feel blunt.
Still, for most portfolios, total market funds act as an anchor. Advisors recommend pairing them with international ETFs, bonds, or alternative assets for balance. The simplicity and cost efficiency are hard to beat. For new investors, starting with a total market ETF eliminates the guesswork—and the temptation to chase performance.
Future Trends: How Innovations and Market Changes Will Shape Total Market Investing
Fund management is poised for another shakeup. AI-powered portfolio optimization could drive expense ratios even lower, with funds competing on features like real-time tax-loss harvesting or ESG overlays. Direct indexing—a niche today—may soon let investors customize broad-market exposure at scale, bypassing ETFs for personalized portfolios.
Regulatory scrutiny is a wild card. The SEC has signaled interest in tighter oversight of ETF disclosures and liquidity. Any new rules could raise costs or restrict fund structures, but so far, the trend favors investor-friendly reforms. Meanwhile, the rise of fractional shares and zero-commission trading has made market ownership frictionless—even for accounts with $50.
Market composition is another variable. The dominance of mega-cap tech firms—Apple, Microsoft, Nvidia—means total market funds are less diversified than they appear. If the top 10 stocks drive 30% of index returns, investors face concentration risk. A reversion to mean, or new sector leadership, could shift performance dynamics.
The next decade will likely see continued fee compression, smarter fund tools, and wider access. Investors who embrace total market funds will capture more upside with less hassle—but must stay alert to shifts in market structure and regulation. The cheap way to own the U.S. stock market is here to stay. What’s uncertain is how the market itself will evolve beneath the surface.
