Compared to the S&P 500, this popular ETF provides investors with added exposure to smaller companies in the U.S. economy.
This product generated a total return of 287% in the past decade, and it carries a low expense ratio of 0.03%.
Investors that are skeptical about the future performance of the most valuable stocks will find that this ETF makes sense for their portfolios.
Founded in 1975, Vanguard is highly regarded as a leading investment firm. It pioneered low-cost investment vehicles, which helped to democratize access to the stock market for individuals. With trillions of dollars in assets under management and a long list of exchange-traded funds (ETFs) to choose from, though, investors might struggle to find the right product for their needs.
Maybe it's a good idea to start with one of the most popular offerings, the Vanguard Total Stock Market ETF (NYSEMKT: VTI). Is it the best buy for long-term investors right now?

Investors are familiar with the S&P 500 index, which tracks the performance of 500 large and profitable businesses in the U.S. But most might not know about the Vanguard Total Stock Market ETF. This portfolio contains more than 3,500 stocks in total. As that indicates, its objective is to provide direct exposure to the entire American stock market.
Companies in all sectors and of all sizes are included. At the top of the list are the high-powered tech titans. Nvidia, Apple, and Microsoft combine to make up 16.7% of the fund's asset base. At the other end of the spectrum are obscure and unfamiliar names, which have tiny market caps.
Unsurprisingly, the technology sector has the highest weighting at 36.3%, followed by consumer discretionary and industrials. This is representative of the broader U.S. economy.
In the past decade, the Vanguard Total Stock Market ETF generated a total return of 287% (as of April 23). Investors reaped the rewards by paying a low expense ratio of 0.03%.
The bull case for investing in the Vanguard Total Stock Market ETF right now is clear. Investors might be skeptical that the largest businesses, primarily the "Magnificent Seven" stocks, will continue their stellar performance over the next five or 10 years. Perhaps the worries stem from elevated valuations and extreme concentration.
This ETF ensures you gain adequate exposure to small-cap and mid-cap stocks, something the S&P 500 doesn't offer. There's a chance that these companies will contribute to strong gains in the future.
The bear case deserves attention as well. Investing in shares of the most dominant companies has worked out extremely well. And given that these are typically high-quality businesses with unrivaled access to capital markets, global customer bases, huge profits, and sustainable competitive advantages, it makes sense to remain focused on such companies.
I sit somewhere between the bull and bear cases. While I wouldn't say that Vanguard Total Stock Market ETF is absolutely the best opportunity right now given current market conditions, it's certainly worth considering as part of a diversified portfolio.

Four leading AI models discuss this article
"VTI's market-cap weighting renders its 'diversification' into small-caps statistically negligible, leaving investors just as exposed to mega-cap concentration as they are in the S&P 500."
The article frames VTI as a 'diversification' play against S&P 500 concentration, but this is mathematically misleading. With a 36.3% tech weight and 16.7% in just three mega-caps, VTI is effectively a leveraged bet on the same 'Magnificent Seven' momentum as the S&P 500 (VOO). The 'small-cap exposure' is a rounding error in a market-cap-weighted fund; you aren't getting meaningful exposure to the Russell 2000's risk-reward profile. VTI is a fine 'set-and-forget' vehicle for passive investors, but it fails as a tactical hedge against mega-cap overvaluation. Investors seeking genuine small-cap exposure should look at dedicated factor ETFs, not a total market index.
VTI's low 0.03% expense ratio and massive liquidity provide a structural efficiency that active small-cap managers rarely overcome after fees, making it the superior choice for the vast majority of retail investors.
"VTI's market-cap weighting delivers negligible small-cap diversification, making it unlikely to outperform S&P 500 ETFs amid ongoing mega-cap dominance."
VTI offers broad U.S. market exposure via market-cap weighting, but its 36.3% tech allocation and 16.7% in Nvidia/Apple/Microsoft mirror S&P 500 concentrations closely—correlation exceeds 0.99 historically. Small/mid-caps comprise just ~6-7% of assets despite 3,500+ holdings, so the 'added exposure' bull case is overstated; VTI underperformed S&P 500 over the last 5 years (VTI +98% vs. SPY +113% as of Apr 2024). With mega-caps driving returns amid AI tailwinds and high rates pressuring leveraged small-caps, VTI isn't a compelling 'best buy' now—better as a set-it-and-forget-it core holding than active bet.
If the Fed slashes rates multiple times in 2024-25 sparking a small-cap rotation (as seen in 2023's brief IWM rally), VTI could outperform S&P 500 by 5-10% annually over 3-5 years.
"VTI's decade-long outperformance is almost entirely attributable to the mega-cap concentration it purports to reduce, making it a poor hedge against the exact risk the article identifies."
This article is marketing disguised as analysis. VTI's 287% decade return is largely attributable to the same 'Magnificent Seven' concentration it claims to diversify away from—tech is 36.3% of holdings. The 0.03% expense ratio is real but irrelevant when the fund's performance is driven by mega-cap momentum. More concerning: the article never addresses valuation. At current multiples, small-cap outperformance would require either multiple expansion (unlikely if rates stay elevated) or a genuine earnings surprise from mid/small caps. The author's hedge—'somewhere between bull and bear'—signals genuine uncertainty, yet the headline pushes readers toward VTI anyway. The Motley Fool disclosure at the end (hawking their 'best 10 stocks' list) reveals the real agenda.
VTI's small-cap/mid-cap exposure genuinely does offer diversification benefits if you believe the next decade favors breadth over concentration—and mean reversion from mega-cap dominance is a legitimate historical pattern, not a contrarian fantasy.
"The main takeaway is that VTI remains a solid long-run anchor, but its 'best buy' label hinges on AI mega-cap leadership continuing; if that leadership falters, breadth may not save you from a multi-year drawdown."
VTI offers low-cost, broad exposure to the U.S. equity universe, and that matters for long-horizon investors. But the article glosses over two real risks: concentration and regime risk. A sizable chunk of performance hinges on a handful of mega-cap tech names (Nvidia, Apple, Microsoft), and the tech tilt (36% weight) means a cliff-edge for performance if AI-driven growth slows or multiples compress. While breadth helps, small- and mid-caps historically swing more with cycles, and today’s market looks expensive relative to historical norms. So, 'best buy' depends on your confidence that mega-cap leadership continues and that the macro regime won’t punish breadth.
Counter: The article compounds the bull case by assuming mega-cap leadership persists. If AI enthusiasm wanes, VTI's heavy tech tilt could amplify losses and diversification may not shield you from a broad market downturn.
"VTI's massive scale creates a structural drag that prevents it from effectively capturing a small-cap rotation compared to dedicated factor-based ETFs."
Claude, you correctly identified the Motley Fool's marketing agenda, but everyone is missing the liquidity trap risk. VTI’s massive AUM forces it to hold illiquid small-cap names that act as dead weight during volatility. If we see a genuine rotation into smaller firms, VTI’s market-cap weighting will force it to chase late-cycle winners rather than capturing the fundamental value of the small-cap factor. We are debating index composition while ignoring the structural drag of index-fund bloat.
"VTI's massive AUM boosts trading liquidity and minimizes small-cap drag risks, contrary to the 'trap' narrative."
Gemini, your liquidity trap argument flips reality: VTI's $1.6T AUM ensures unmatched ETF liquidity for investors (spreads <1bp), while tiny small-cap weights (~6%) mean negligible drag even in rotations. Index bloat affects active managers more; VTI's passive structure auto-captures winners via market-cap weighting without front-running errors. The real structural risk is over-reliance on quarterly rebalances amid volatility spikes.
"VTI's external liquidity doesn't solve the problem of forced accumulation in illiquid small-cap positions during factor rotations."
Grok's rebuttal on liquidity misses Gemini's actual point. Yes, VTI has tight spreads for retail buyers—that's not the issue. The problem is forced holding of illiquid small-cap names during rotations. When $1.6T must rebalance into a 6% allocation of thinly-traded names, VTI becomes a price-taker, not a liquidity provider. Grok conflates ETF-level liquidity with underlying holdings' liquidity. These are different risks.
"Rotation-driven price impact in VTI during small-cap rotations creates drag, undermining its use as a hedge; explicit small-cap or factor tilts may be more reliable."
Claude's liquidity distinction is fair, but the bigger, overlooked flaw is rotation-driven price impact in VTI during small-/mid-cap rotations. Even with 0.03% expense and tight ETF spreads, quarterly rebalances into a 6% small-cap sleeve can force VTI to chase thin names at inopportune moments, creating drag when market regimes flip. That undermines VTI as a tactical hedge—consider explicit small-cap or factor tilts for diversification instead.
The panel generally agrees that VTI offers broad exposure but fails as a tactical hedge against mega-cap overvaluation due to high tech concentration and small-cap weight being a 'rounding error'. They also highlight risks such as liquidity trap, rotation-driven price impact, and over-reliance on quarterly rebalances.
