Small-Cap Growth Showdown: IJT’s Yield vs. VBK’s Cost Efficiency

The small-cap growth sector has long been the battleground for investors seeking the next generation of market leaders. In the current market landscape of early 2026, two titans of the ETF world—the iShares S&P Small-Cap 600 Growth ETF (IJT) and the Vanguard Small-Cap Growth ETF (VBK)—continue to offer distinct paths for capturing this segment. While both funds target small companies with high growth potential, the structural differences between their underlying indices create a divergence in yield and cost that can significantly impact long-term portfolio performance.

The primary differentiator for IJT lies in its adherence to the S&P Small-Cap 600 Growth Index. Unlike many small-cap benchmarks, the S&P 600 employs a strict profitability requirement: companies must report positive earnings over the most recent quarter and the sum of the last four quarters to be eligible for inclusion. This quality screen effectively filters out many of the more speculative, cash-burning startups that often populate the small-cap growth space. As a result, IJT tends to hold more mature, financially stable companies. This focus on profitability is the direct driver of the higher dividend yield mentioned in recent market reports. While growth stocks are not typically prized for their dividends, the relative stability of IJT’s holdings allows for a more consistent, albeit modest, income stream compared to its peers.

For an investor with a multi-decade horizon, the compounding effect of saving approximately 11 basis points annually—the current gap between VBK’s 0.07% and IJT’s 0.18%—can amount to thousands of dollars in retained capital over time.

In contrast, the Vanguard Small-Cap Growth ETF (VBK) tracks the CRSP US Small Cap Growth Index. This benchmark is notably broader and does not impose the same stringent profitability hurdles as the S&P 600. By including a wider array of companies, VBK offers more pure exposure to the growth factor, capturing firms that may still be in their heavy-investment, pre-profitability phases. This broader reach can be a double-edged sword; it allows investors to participate in the rapid ascent of early-stage winners, but it also exposes the fund to greater downside risk during periods of economic contraction or rising interest rates, when non-profitable firms are hit hardest.

The affordability of VBK is its most compelling selling point. Vanguard’s legendary focus on low-cost investing is evident here, with VBK maintaining an expense ratio that is significantly lower than IJT’s. In the world of passive indexing, where tracking error is minimal, the expense ratio is often the single most important predictor of long-term outperformance. For an investor with a multi-decade horizon, the compounding effect of saving approximately 11 basis points annually—the current gap between VBK’s 0.07% and IJT’s 0.18%—can amount to thousands of dollars in retained capital over time.
