Should You Consider Adding Vanguard S&P Mid-Cap 400 Index Fund ETF Shares (IVOO) to Your Investment Watchlist?

Overview of Vanguard S&P Mid-Cap 400 ETF (IVOO)

Launched on September 9, 2010, the Vanguard S&P Mid-Cap 400 Index Fund ETF Shares (IVOO) is a passively managed exchange-traded fund that aims to provide investors with comprehensive access to the U.S. mid-cap blend equity market.

Managed by Vanguard, this fund has accumulated more than $3.18 billion in assets, positioning it as a mid-sized ETF within its category.

Advantages of Investing in Mid Cap Blend

Mid-cap companies, typically valued between $2 billion and $10 billion, often offer a favorable mix of growth potential and stability. These firms generally experience faster growth than large caps and less volatility than small caps, making them attractive to investors seeking a balanced approach.

Blend ETFs, such as IVOO, typically include a combination of growth and value stocks, as well as those that display characteristics of both.

Expense Ratio and Yield

When comparing ETFs, the expense ratio is a key factor, as lower costs can enhance returns over time. IVOO stands out with an annual expense ratio of just 0.07%, making it one of the more affordable options in its segment.

Additionally, the ETF offers a trailing 12-month dividend yield of 1.29%.

Portfolio Composition and Leading Holdings

Although ETFs are designed to provide diversified exposure and reduce the risk associated with individual stocks, it's still wise to review a fund's holdings before investing. Most ETFs, including IVOO, are highly transparent and disclose their portfolios daily.

IVOO allocates roughly 25% of its assets to the Industrials sector, with Financials and Information Technology also making up significant portions of the portfolio.

Among its largest individual holdings are Ciena Corp (CIEN), representing about 1.02% of assets, followed by Coherent Corp (COHR) and Lumentum Holdings Inc (LITE). The top ten holdings collectively account for approximately 4.74% of the fund's total assets.

Performance and Risk Profile

The fund seeks to replicate the performance of the S&P MidCap 400 Index, which tracks 400 U.S. mid-cap stocks using a capitalization-weighted methodology. Before fees and expenses, IVOO aims to mirror this index's returns.

Year-to-date, IVOO has gained around 4.38%, and over the past year (as of March 10, 2026), it has risen by about 16.77%. During the previous 52 weeks, its share price has ranged from $86.58 to $122.12.

With a beta of 1.04 and a three-year standard deviation of 17.97%, IVOO is considered a moderate-risk investment. The fund holds approximately 408 stocks, providing broad diversification and reducing company-specific risk.

Comparable ETF Options

IVOO carries a Zacks ETF Rank of 2 (Buy), reflecting factors such as expected returns, cost efficiency, and momentum. This makes it a strong choice for investors interested in the mid-cap blend segment. However, there are other ETFs in this space worth considering.

For example, the Vanguard Mid-Cap Index Fund ETF Shares (VO) and the iShares Core S&P Mid-Cap ETF (IJH) also track similar indexes. VO manages $94.66 billion in assets with a 0.03% expense ratio, while IJH oversees $107.65 billion and charges 0.05% in annual fees.

Conclusion

Passively managed ETFs like IVOO are gaining traction among both institutional and individual investors due to their low fees, transparency, flexibility, and tax advantages. They are particularly well-suited for those with a long-term investment horizon.
