Vanguard funds have long been popular choices for investors seeking low-cost index funds ideal for a buy-and-hold strategy.

In the exchange-traded fund space, the [**Vanguard S&amp;P 500 ETF (VOO)**](https://www.etf.com/VOO) and the [**Vanguard Total Stock Market ETF (VTI)**](https://www.etf.com/VTI) are prime examples.

While VOO tracks the S&amp;P 500 index, VTI tracks the broader CRSP US Total Market Index. Both exchange-traded funds can serve as a core holding in a long-term portfolio for almost any investor, from beginners to seasoned investors to professional money managers.

But which of these stock funds is best for your portfolio?

We provide a close look at VOO and VTI, covering the costs and key performance metrics, as well as their similarities and differences.

## VTI vs VOO: Similarities and Differences 

VOO and VTI are both popular [Vanguard funds](https://www.etf.com/topics/vanguard) that offer broad exposure to the U.S. stock market. VOO tracks the S&amp;P 500, focusing on large-cap companies, while VTI tracks the total U.S. stock market, including companies of all sizes.

### Similarities

- **Diversified choices:** Both Vanguard funds offer diversification by investing in a broad range of U.S. companies.
- **Cap-weighted, large-cap focus:** While VTI and VOO are diversified funds, they both track a cap-weighted index, which means companies with the largest market caps receive the highest allocations, making them both mega-cap-dominated funds.
- **Low-cost:** Both ETFs are known for their low expense ratios, each at 0.03%, making them attractive to cost-conscious investors.

### Differences

- **Focus:** VTI tracks the total U.S. stock market, including companies of all sizes. VOO focuses on large-cap companies, tracking the S&amp;P 500 Index.
- **Diversification:** VTI offers broader diversification by including companies of all sizes, while VOO's focus on large-cap companies may provide a slightly less diversified exposure.
- **Performance:** The performance of VTI and VOO can vary depending on the performance of the underlying indexes. VTI may have slightly higher volatility due to its inclusion of smaller-cap stocks.

### Breaking Down VTI and VOO ETF Performance

VTI provides broader diversification but has produced slightly lower returns in the past decade due to its inclusion of smaller-cap stocks. Remember that small-caps have historically outperformed large-caps. So, if history repeats or rhymes, the recent dominance of the latter may not continue over the next decade.

## Bottom Line: VTI or VOO?

VTI and VOO are suitable choices for investors seeking broad exposure to the U.S. stock market. If you prefer a more diversified portfolio, VTI may be a better option, as it includes all VOO’s holdings, plus smaller companies. If you're comfortable with the concentration on larger-cap companies or are building a broader portfolio to include other funds, VOO can be a suitable choice.
