DFMC targets the smallest publicly traded U.S. companies, typically those below $300 million market cap that institutional investors largely ignore. This is Dimensional's systematic approach to capturing the microcap premium that academic research has documented but most funds can't efficiently access.
How It Works
Rather than tracking a standard microcap index, Dimensional applies its factor-based methodology to this universe, likely tilting toward value and profitability metrics while maintaining broad diversification across hundreds of tiny stocks. The fund probably rebalances opportunistically to minimize trading costs in these less liquid names, using patient block trading and crossing opportunities within Dimensional's fund complex.
Key Features
- Access to 500+ microcaps too small for Russell 2000, where size premium historically strongest
- Dimensional's systematic approach avoids lottery-ticket stocks that plague passive microcap indexes
- Lower turnover than index funds through flexible implementation and internal crossing
Risks
- Microcaps can drop 50%+ in market stress as liquidity evaporates and spreads widen to 5-10%
- Many holdings are unprofitable companies that could go to zero in economic downturns
- Fund could underperform microcap indexes by 10%+ if value/profitability factors don't work in this segment
Who Should Own This
Best for patient investors who already own core equity exposure and want to complete their U.S. allocation with a 5-10% microcap sleeve. You need a 10+ year horizon and the stomach for extreme volatility — this isn't for anyone who checks their portfolio daily or needs liquidity within 5 years.
