Key insights

  • 🍽️
    International diversification is a "free lunch" in portfolio construction, both theoretically and empirically, providing critical benefits.
  • 💼
    Diversifying a portfolio across imperfectly correlated assets allows investors to increase their expected returns without increasing their risk or decrease their risk without reducing their expected returns.
  • 💰
    Adjusting for valuation changes is important when estimating expected returns, as higher stock prices can indicate lower expected returns.
  • 💰
    The currently high valuations of U.S. stocks pose an additional hurdle to overcome, making it uncertain whether there will be enough luck and learning-related valuation increases to propel U.S. stocks ahead of the rest of the world in the long term.
  • 📈
    While global diversification may disappoint in the short-term due to simultaneous market crashes, long-term returns are crucial for wealth creation.
  • 📈
    The chance of losing purchasing power in domestic stocks at the 30-year horizon is higher (13%) compared to international stocks (4%).
  • 💼
    International value and small cap value stocks may offer portfolio improvements above and beyond those offered by International Market indexes.
  • 📈
    Relying solely on past success of a single market can be misleading, as future returns are less likely to reflect the past due to the uncertainty of which markets will be most successful in terms of investment returns.

Q&A

  • Why is international diversification important for portfolio construction?

    — International diversification is crucial for sensible portfolio construction as it allows investors to increase expected returns without increasing risk or decrease risk without reducing expected returns.

  • Can international diversification decrease risk without reducing expected returns?

    — Yes, diversifying a portfolio across imperfectly correlated assets, such as international stocks, allows investors to decrease risk without reducing expected returns.

  • Why is adjusting for valuation changes important in estimating expected returns?

    — Adjusting for valuation changes is crucial in estimating expected returns because historical data cannot predict the best performing markets, and valuation changes play a significant role in determining future returns.

  • Have U.S equity returns exceeded their expected returns?

    — Yes, U.S equity returns have exceeded their own expected returns by about two percent per year, which can be attributed to luck and learning, but it is uncertain if this trend will continue in the future.

  • Does international diversification protect against poor long-term returns in specific countries?

    — Yes, international diversification protects investors against holding concentrated positions in countries with poor long-term returns, despite short-term disappointments due to market crashes.
