Vanguard Tax-Managed Capital Appreciation captures most of the US stock market while seeking to minimize investors’ tax bills.
The fund uses the Russell 1000 Index to model its holdings. The index market-cap weights the largest 1,000 US stocks, or roughly 93% of the US stock market. As a result, the fund experiences little turnover because of the minuscule average size of additions or deletions to the existing portfolio. Stocks must pass an eligibility screen that ensures they are easy to trade, and buffer rules prevent further turnover and its associated costs.
The fund market-cap weights stocks from the Russell 1000 Index and excludes a small portion of its holdings to lower the fund’s tax bill. It usually omits smaller, high-dividend-paying stocks to boost tax efficiency with minimal impact on the portfolio’s ability to accurately represent the US stock market.
Assigning position sizes based on a stock’s market cap is a simple and efficient method to weight the portfolio. Since US stocks are highly traded, they quickly reflect new information, and gaining an edge is difficult. Market-cap weighting naturally adjusts to price changes without frequent rebalancing, lowering trading costs. That, and lower fees, gives large-blend index funds a long-term performance advantage over most actively managed peers.
The portfolio is broad and well-diversified. It typically holds around 800 stocks, and the top 10 represented 36% of the portfolio as of year-end 2025. Still, market-cap weighting can contribute to portfolio concentration when a few stocks dominate the market. This has been the case lately with a handful of mega-cap technology stocks growing to prominence and commanding a greater share of the portfolio.
When a few richly valued companies or sectors power most of the market gains, the strategy's market-cap weighting may overexpose it to the fluctuations of one stock or sector. But this is not a fault in design, as it simply reflects the market’s composition. Its low turnover, low fee, and broad diversification across the US market more than offset these risks.
The fund returned 15.5% annualized over the past 10 years through January 2026. It holds little cash, which should help it outperform cash-saddled active peers during market rallies. Likewise, low cash drag could hurt this fund when the stock market declines, but long-term positive results for the US market have given this efficient approach an edge.
