Summary

David Booth, co-founder of Dimensional Fund Advisors, discusses his book 'Stay Calm' and argues that investors should stay calm, stay invested, and avoid trying to outguess the market. He cites long-term stock returns near 10% and bond returns near 4-5%, says professional managers generally fail to beat the market, and defends index-based investing as still price-efficient. The conversation also touches on Dimensional's ETF share classes, fee compression, and his optimism about public markets.

  • Booth says panic selling during 2020 caused investors to miss a sharp rebound.
  • He states long-run stocks return about 10% annually and bonds about 4-5%.
  • He argues active managers generally do not beat the market, favoring low-cost indexing.
  • He says rising index ownership has not made markets inefficient because trading volume remains high.
  • He expects AI and better data processing to make markets more efficient.
  • Dimensional added ETF share classes mainly to make investing easier.
  • Booth expresses optimism about public markets despite widespread anxiety.
Ideas

Stay invested in stocks through volatility.
Booth argues investors should stay invested in equities through volatility instead of panicking. He uses 2020 as an example: the market fell more than 20% in Q1 on pandemic fears, then rose about 50% over the next nine months, and long-term stocks return about 10% annually only for those who remain invested.

Buy broad index funds, avoid active.
Sixty years of data show professional managers generally fail to beat the market, so ordinary investors can do as well as insiders by buying the broad market inexpensively through index funds instead of paying for active management.
