VBK targets the fastest-growing companies among U.S. small caps, capturing firms with aggressive expansion characteristics like high sales growth and earnings momentum. This concentrated growth approach has historically delivered higher returns than broad small-cap exposure during bull markets, though with significantly more volatility.
How It Works
The fund tracks the CRSP US Small Cap Growth Index, which ranks stocks by growth factors including 3-year historical sales and earnings growth, current investment-to-assets ratios, and return on assets. It uses market-cap weighting within the growth universe, meaning the largest small-cap growth stocks dominate. The index reconstitutes annually and makes quarterly adjustments, creating moderate turnover as companies graduate to mid-cap status or lose their growth characteristics.
Key Features
- Captures ~600 high-octane growth stocks vs ~1,400 in broad small-cap funds
- Rock-bottom 0.07% expense ratio crushes active small-cap growth funds averaging 1%+
- More tech/healthcare exposure (40%+) than value counterpart VBR's industrials/financials tilt
Risks
- Growth stocks can crater 40-50% in recessions as investors flee to quality
- Small caps already volatile; growth filter amplifies swings by 20-30% vs broad market
- Vulnerable to rising rates when expensive growth multiples get compressed
Who Should Own This
Best for aggressive investors with 10+ year horizons who can stomach seeing their position cut in half during downturns. Works as a 5-10% satellite holding to juice returns in a diversified portfolio, or as a tactical play when you believe small growth companies will outperform. Not suitable for anyone who'll panic sell after a 30% drawdown.
