SCHX delivers exposure to the largest U.S. companies at rock-bottom cost, tracking the Dow Jones U.S. Large-Cap Total Stock Market Index. This fund captures roughly the top 750 stocks by market cap, representing about 90% of total U.S. market value.
How It Works
The fund uses full replication to hold all constituents of its index, which includes companies with market caps typically above $12 billion. Unlike S&P 500 funds, SCHX uses a broader definition of 'large-cap' and includes all eligible stocks without a selection committee. The index rebalances quarterly and weights holdings by float-adjusted market cap, meaning bigger companies get proportionally larger allocations.
Key Features
- Broader than S&P 500 with ~750 holdings vs 500, capturing more of the large-cap universe
- Among the cheapest large-cap options available, undercutting even Vanguard's offerings
- No selection committee means purely rules-based inclusion, avoiding subjective stock picks
Risks
- Tech concentration risk with top holdings potentially representing 30%+ of the portfolio during bull markets
- Large-cap bias means missing gains from mid and small-cap outperformance cycles, which historically happens every 3-5 years
- Market cap weighting amplifies bubble risks — overvalued stocks automatically get bigger positions
Who Should Own This
Perfect for cost-conscious investors building a core equity position who want slightly broader exposure than the S&P 500. Works best as a portfolio anchor for those who plan to add factor tilts or international exposure separately. The ultra-low cost makes it ideal for tax-loss harvesting pairs with similar funds like VTI or VOO.
