About this page
Profiles of the investors whose ideas still shape how money is managed, grouped by style: what each of them actually believed, the conditions their approach was built for, and where it struggled. The point is the reasoning, not the hero worship.
Each profile is paired with the closest portfolio that can be tested, so an idea does not have to stay an idea. If a philosophy can be expressed as an allocation, you can see how that allocation behaved through real decades, including the ones that would have been painful to hold.
Should I copy a famous investor's portfolio?
Their results came with a time horizon, a capital base and a tolerance for losses that may not be yours. Treat these as case studies in reasoning, then test any allocation you like against a period you would actually have lived through.
Why do so many of these approaches disagree?
Because they were built for different problems. Value, momentum, macro and quality each have long stretches where they look obviously right and long stretches where they look broken.
