Diversification & Global Investing
Diversification spreads risk across uncorrelated assets and geographies.
Viewpoints

Escobari: US market overvaluation creates case for global diversification
Martín Escobari
“US equity markets are trading at historically expensive valuations (26x earnings at the 97th percentile over 25 years) while the dollar remains overvalued, creating a compelling case for geographic diversification beyond US assets. Despite the US remaining the world's top economy, concentration risk is elevated when US public equities command such a premium relative to international markets, especially given US debt-to-GDP ratios at 125% exceeding post-WWII levels.”

Philbrick: Economic regimes require different asset classes for diversification
Mike Philbrick
“Different economic regimes favor different asset classes: rising inflation with accelerating growth benefits commodities and emerging markets; falling inflation with accelerating growth favors US equities; stagflation hurts both bonds and equities while helping gold; deflationary busts favor bonds and gold. Since predicting these regimes is difficult, a balanced portfolio should own all major asset classes in equal weights to manage risk across various economic scenarios.”

Faber: US concentration repeats historical bubbles, diversification needed
Meb Faber
“Concentration in US tech stocks mirrors historical patterns like the railroad bubble 100 years ago, when boring utilities reached PE ratios of 50-60 before US stocks crashed 80%. The creative destruction of capital markets means today's top companies won't remain dominant, as evidenced by how the world's top 10 stocks change every decade. International markets offer lower valuations and counter the false narrative that only US tech can produce innovative companies.”

Grieve: Home country bias justified when domestic opportunities are abundant
Kyle Grieve
“While investors should look beyond their home country to avoid bias, the imperative for global diversification diminishes when domestic markets offer abundant opportunities. Understanding your home country deeply, combined with access to local expertise for unfamiliar sectors, provides significant advantages over investing abroad where such knowledge networks are unavailable. The speaker maintains that global investing is worth exploring but has learned through mixed results (including a categorical rejection of Chinese investments) that geographic familiarity matters substantially.”
Key Moments

Goetzmann: Global diversification protects against missing international outperformance
Will Goetzmann
“Global diversification is important because different markets can significantly outperform others in ways that aren't always predictable. For example, in 2005, global equity markets substantially outperformed the US stock market, illustrating that concentrating investments domestically can lead to missed opportunities. This historical example serves as a reminder to regularly check and maintain global diversification through mutual funds, ETFs, or pre-made diversified portfolios.”

Cukierwar: Framework enables global investing despite local knowledge gaps
Jon Cukierwar
“Investing globally requires accounting for difficult-to- understand variables like regulation, culture, sentiment, and political motivations in foreign countries. However, a consistent framework for identifying good businesses can work across different markets (US, Canada, Australia, UK, Poland), especially when supplemented by relationships with local management teams who provide on-the-ground insights that help bridge the circle of competence gap.”
