Munger’s 19.8% CAGR at Berkshire is verified from SEC filings. The BYD pick returned 8-10x. See’s Candies generated $2B+ on a $25M investment. But the record includes blind spots (missing Google, Amazon) and errors (Alibaba loss at DJCO). Berkshire’s outperformance narrowed significantly from 2009-2020.
So what
Munger’s investment track record is extraordinary and verified by decades of SEC filings. The headline numbers are real. But the full picture is more nuanced: outperformance has narrowed since 2009, the Alibaba bet was a late-career error, and massive misses on tech giants exposed blind spots in the mental models framework. The most honest takeaway: Munger was one of the greatest investors ever, AND his approach has significant limitations, AND survivorship bias means we should be cautious about generalizing from his example.
