Exploring Small-Cap Funds for Diversification
For investors eager to pull away from the overwhelming presence of mega-cap stocks, small-cap funds often come into play. These funds have the potential to spotlight the next wave of industry leaders. While small-cap stocks can boast better growth opportunities than their larger counterparts, they also tend to experience more pronounced price swings.
Two prominent options in this area are the Vanguard Small Cap ETF (VB +1.17%) and the iShares Morningstar Small Cap ETF (ISCB +1.37%). Aiming at this market segment, they provide cost-effective exposure to a multitude of small U.S. companies that often fly under the radar of major indexes.
The Vanguard Small Cap ETF is known for its excellent liquidity and low expense ratio. In contrast, the iShares Morningstar Small Cap ETF offers wider diversification with over 1,500 holdings and a slightly higher dividend yield.
Cost and Size Comparison
| Metric | VB | ISCB |
|---|---|---|
| Publisher | Vanguard | iShares |
| Expense Ratio | 0.03% | 0.04% |
| 1-Year Return (as of June 17, 2026) | 29.90% | 31.60% |
| Dividend Yield | 1.20% | 1.30% |
| Beta | 1.04 | 1.05 |
| Assets Under Management | $182.7 billion | $286.2 million |
The Beta value measures a stock’s price volatility relative to the S&P 500, calculated from five years of monthly returns. The one-year return reflects total earnings for the next 12 months, while the dividend yield represents the trailing 12-month distribution yield.
The Vanguard Fund holds a slight edge with its lower expense ratio of 0.03%, compared to the iShares Fund’s 0.04%. While this one basis point difference may seem minimal, for those with significant investments, it can notably influence compound interest over time. The yields between the two are fairly comparable, with ISCB’s at 1.30% against VB’s 1.20%.
Performance and Risk Overview
| Metric | VB | ISCB |
|---|---|---|
| Maximum Drawdown (5 years) | (28.20%) | (29.90%) |
| $1,000 Growth in 5 years (Total Return) | $1,446 | $1,368 |
Portfolio Breakdown
The iShares Morningstar Small Cap ETF includes 1,544 stocks, crafted to mirror the market performance of small to medium-sized U.S. companies. This extensive diversification helps cushion the effects of a single company’s poor performance on the overall portfolio.
I mean, its sector allocation is about 18% in industrials, 16% in financial services, and 15% in technology. Key positions in this fund include: Lumentum Holdings (Light 2.30%), Revolutionary Medicine (RVMD +3.31%), and ATI (ATI +2.29%).
In contrast, the Vanguard Small Cap ETF manages 1,357 stocks and aims to replicate the CRSP U.S. Small Cap Index using a closely aligned replication method. Its sector distribution leans more toward 21% in industrials, 17% in technology, and 13% in financial services. Prominent holdings here are: Flex Co., Ltd. (flex +2.96%), Astera Research Institute (ALAB +11.28%), and Sienna Corporation (Sien 1.95%).
Implications for Investors
Incorporating small-cap stocks into your investment strategy could be an effective way to tap into high-growth companies that are typically not well-known, like Astera Labs. Investing through vehicles such as the iShares Morningstar Small Cap ETF or the Vanguard Small Cap ETF makes this process more efficient. Ultimately, choosing between the two hinges on several key factors.
While ISCB does present a slight edge in terms of dividend yield, appealing to those focused on income, it has shown strong performance over the year. Its extensive holdings offer broad exposure, though the inherent volatility of smaller companies could pose a risk, as highlighted by ISCB’s maximum drawdown.
On the other hand, the considerable assets under management in VB provide better liquidity and can help minimize trading costs. Additionally, Vanguard’s recent cut in VB’s expense ratio makes it even more attractive, arguably more so than ISCB. Hence, VB could be the go-to fund for long-term investors looking to buy and hold.
