What this means for investors

Small-cap stocks have a well-established reputation for outperforming large caps over long time horizons, but that reputation comes with an asterisk. The ride is rougher, the companies are less proven, and the universe includes plenty of businesses that never fulfill their early promise. You want to understand how a fund actually navigates that universe.

VB takes the broadest possible approach by holding more than 1,300 small-cap companies across the entire small-cap spectrum. Its massive scale provides liquidity that smaller funds simply cannot match. BBSC targets a more specific slice of the market, focusing on companies between the 95th and 99th percentiles in market capitalization. That precision gives it a tighter, more defined small-cap profile than VB's broader sweep, but at a higher fee and with far less liquidity.

For most long-term investors, VB's lower cost, broader diversification, and institutional scale make it the more dependable foundation for small-cap exposure. BBSC is better for investors who specifically want a narrower, more defined slice of the small-cap universe and are comfortable with a smaller, less liquid fund to get it.
