The Investor’s Superpower: Admitting “I Don’t Know”
Sep 29, 2026 · 15m
Summary
Host David Coombs argues that investors should stop trying to predict macroeconomic variables like interest rates, oil prices, and political outcomes, as even experts cannot forecast these with certainty. Instead, he advocates for Benjamin Graham’s margin of safety and Warren Buffett’s focus on intrinsic value, suggesting that analyzing a specific business’s financials is far more manageable than forecasting the global economy. By accepting uncertainty and focusing on buying strong businesses at sensible prices, investors can protect their portfolios against unforeseen future events.
