What is the average return of small-cap index funds?

From 1972 to 2022, small-cap funds averaged a total annual return of 11.5%, slightly better than that of large-cap funds.

What is the minimum investment in small cap index?

Minimum investment thresholds vary by company, but many offer small-cap indexes with no minimum investment required.

What is the difference between small-cap and large-cap index funds?

As the name implies, small-cap and large-cap funds differ in the size of the companies they buy. Small-cap funds invest exclusively in companies that have relatively small market capitalizations, while large-cap funds invest only in companies with large market capitalizations. The definitions of "small" and "large" vary by company, but small-cap stocks are generally companies with a market capitalization between $300 million and $2 billion.

Do small caps outperform the S&P 500?

Over long periods, small-cap stock indexes tend to outperform the S&P 500, but returns can vary. Over some periods, the S&P 500 has outperformed small caps by a significant margin.

How are small-cap index funds taxed?

Small-cap index funds are taxed on dividends and capital gains distributions, which are treated as short-term or long-term depending on an investor's holding period and a fund's holding period for individual investments. Funds held in tax-sheltered accounts, including retirement accounts, are not subject to annual taxation.

Who should invest in a small-cap index fund?

Investors with a long-term horizon who are seeking diversification away from the large stocks that dominate the major indexes might consider a small-cap index fund. Risk-averse or short-term investors might want to limit or avoid small caps as they tend to be more volatile.

Key Points

Small-cap index funds extend broad sector exposure, mitigating risk and increasing potential gains.
iShares Russell 2000 Growth ETF and Schwab U.S. Small-Cap ETF provide targeted small-cap growth and diversified exposure.
Investing in leading small-cap index funds offers strategic benefits and can reduce single-stock risk.

A small-cap index fund is an exchange-traded fund (ETF) or mutual fund that tracks a small-cap benchmark stock index, such as the Russell 2000. Small-cap companies typically have market caps between $300 million and $2 billion, and are often younger, faster-growing businesses.

Small-cap index funds offer four key advantages: portfolio diversification across sectors, risk reduction through broad exposure, bull market outperformance relative to large caps, and attractive long-term growth potential, though with greater volatility during downturns.

If you want broad small-cap exposure, the four index funds below are strong options.

As its name implies, the iShares Russell 2000 Growth ETF aims to track Russell 2000 stocks that exhibit growth characteristics.

This ETF has performed well in bull markets but also falls faster when stocks are down. It is at its best when investors are putting money into smaller, more speculative companies. As the fund's name suggests, it is focused on growth: It aims to provide exposure to small companies with earnings expected to grow at an above-average rate relative to the market.

A growth-oriented fund such as the iShares Russell 2000 Growth ETF carries greater inherent risk, but it offers a reasonable expense ratio of 0.24% for investors seeking small-cap growth.

The Schwab U.S. Small-Cap ETF tracks the small-cap holdings of the Dow Jones U.S. Total Stock Market index. This is sort of a middle-of-the-road index fund ETF. It is neither overly conservative nor too aggressive with its holdings. Since it holds a mix of high- and low-risk stocks, its risk is lower than that of a purely growth-oriented fund. If you're a believer in diversification, this fund provides it.

A low expense ratio of 0.03% and a 10-year compound annual growth rate of more than 10.5% (including dividends) make the ETF an appealing way to invest in domestic small caps. The fund also pays a dividend yielding about 1.02% of the share price as of Summer 2026.

The Vanguard Small-Cap Value Index Fund ETF tracks the CRSP U.S. Small Cap Value index. As a value-oriented index-tracking fund, the ETF doesn't offer the highest share-price growth potential, but it should outperform in bear markets. That's because valuations, especially of high-priced stocks, tend to compress in recessions.

Investors need to be clear about the trade-offs they are making when considering a value fund. This and other value-oriented investments tend to underperform when markets are soaring, but can provide valuable ballast when markets are under pressure.

As of August 2026, the fund offers a dividend yield of about 1.7% and an attractive expense ratio of 0.05%.

Benefits and risks of investing in small-cap index funds

There are some excellent reasons you might want to consider adding small-cap index funds to your portfolio:

Portfolio diversification: Investing in a small-cap index fund exposes your portfolio to a wide range of small-cap stocks across different sectors. Diversified portfolios generally perform better than non-diversified holdings because owning the stocks of many different companies ensures that your portfolio's performance is not strongly correlated with the performance of any specific stock and is more resistant to bear markets.
Risk reduction: Small-cap stocks can be risky because they tend to move in step with the broader economic cycle. They are also more volatile than large-cap stocks. Investing in an index fund eliminates some of the risk because the fund gives you a stake in dozens of companies.
Bull market gains: Although large-cap companies are more likely to be profitable, have better access to capital, and can better withstand recessions, small-cap companies tend to outperform during bull markets, which occur when the stock market is on the rise.
Attractive growth potential: Small-cap stocks have historically outperformed large caps over long periods, thanks to their greater growth potential.

On the other hand, there are some major risk factors and drawbacks to consider:

Volatility: Small-cap stocks are generally considered more volatile than larger companies and can be more vulnerable to market fluctuations and economic headwinds.
Fees: While most small-cap index funds have relatively low costs, this is a drawback of investing in index funds versus individual small-cap stocks. Look for expense ratios on individual fund websites and try to find low-cost options.
