Multidisciplinary Thinking Improves Investing

In this special compilation episode of Excess Returns, we ask one revealing question to some of the most respected investors, strategists, and market thinkers in the industry:

What is one belief you hold about investing that most of your peers would disagree with?

The answers challenge conventional wisdom across macro, valuation, diversification, options, forecasting, AI, and investor behavior.
