Week 26 Day 2: VTI: Own Every American Company in One Fund

VTI is the simplest way to own 'the entire U.S. stock market.' When you buy VTI, you own a tiny piece of Apple, Microsoft, Google, and also thousands of small companies you have never heard of. You get the average return of all U.S. stocks combined. Over the long term, that average has been roughly 10% per year.

VTI by the numbers: Expense ratio: 0.03% ($3 per $10,000 invested annually). Holdings: approximately 3,600 stocks (essentially every investable U.S. company). 10-year annualized return: approximately 12% (varies by ending date). Yield: approximately 1.3%. Top holdings: Apple, Microsoft, NVIDIA, Amazon, Alphabet, Meta (together approximately 25% of the fund). Why VTI is the bedrock: it captures the full U.S. equity premium -- the return you earn for bearing stock market risk. No sector bets, no style bets, no picking winners. Just own everything. Over 90% of professional stock pickers fail to beat VTI over 15+ years. VTI vs SPY (S&P 500): VTI includes roughly 3,100 additional small-cap and mid-cap stocks. Historically, small-caps have provided a slight return premium (the 'size premium'), but it is inconsistent. The practical difference is small -- approximately 0.1-0.3% per year. Either fund is a fine core holding. VTI is slightly more diversified.

VTI tracks the CRSP U.S. Total Market Index, which captures approximately 100% of the investable U.S. equity market. By holding the market portfolio, investors capture the full equity risk premium without factor tilts. Under the Capital Asset Pricing Model (CAPM, Sharpe 1964), the market portfolio is the maximum Sharpe ratio portfolio accessible to all investors. While CAPM is an incomplete model (Fama-French and q-factor models include additional priced factors), the market portfolio remains the benchmark against which all active strategies are measured. Fama and French (2010) showed that the aggregate alpha of all active managers must be zero before costs (because active managers collectively hold the market minus the index -- and both equal the market). After costs, the aggregate alpha is negative by the amount of fees, making the market portfolio (VTI) the default optimal choice for any investor without a validated edge. The practical implication: any portfolio that excludes VTI (or its equivalent) must justify the opportunity cost. Every dollar allocated to sector bets, factor tilts, or alternative strategies is a dollar that is NOT earning the reliably positive equity risk premium. VTI should be the default allocation; everything else should be the exception that must prove its worth.
