Today's conversation was sparked by the excellent piece penned by today’s guest, Victor Haghani, back in November of this year: There's No Place Like Home: The Case For And Against Extreme Home Bias In Equity Investing. With U.S. equities outperforming their international counterparts by as much as 170% over the past decade, it's no wonder that surveys show that U.S. investors typically allocate as much as 80-85% of the equity portion of their portfolios to U.S. domiciled stocks, a condition Victor refers to as "extreme home bias".In the aforementioned article, Victor lays out 10 different arguments investors often make in favor of "extreme home bias", and then debunks them one by one. During our conversation, we take a step back and start by evaluating the evidence for being properly "globally" diversified. We then get into some of the arguments Victor lays out against "extreme home bias", trying to stress test them where we can. Finally, we end with a discussion of the specific ETFs Victor and his partner James White use in constructing properly diversified portfolios - both for their clients and themselves.Show Notes:2:30 - Why do "long-form" research?
