Yet, despite this greater diversification, VB has experienced roughly the same volatility as IJR. Both funds have seen a max drawdown over the last five years of approximately 28%.
Turning to fees, VB offers a very slim advantage over IJR. VB has an expense ratio of 0.05%, while its rival's expense ratio is 0.06%. Meanwhile, in terms of dividend yield, both funds sport very similar dividend yields, with IJR having a dividend yield of 1.4%, and VB having a 1.3% yield.
Lastly, there's performance. On that front, both funds have underperformed the S&P 500 over the last five years. However, VB has generated a higher total return (43%), while IJR has generated a total return of 38%.
In sum, these two small cap funds are quite similar. Nevertheless, there are some differences that could tip the scales in favor of one over another. VB has a stronger historical track record, along with slightly lower fees. Meanwhile, IJR has a marginally higher dividend yield, which could matter to income-seeking investors.
