Survivorship Bias in Private-Market Track Records: How Sponsors Quietly Game the Numbers
Most published private-market returns are biased upward by survivorship. How to read past the bias and see the real picture.
The framework
This article lays out the analytical framework: the inputs that drive the decision, the questions worth asking, and the mistakes that most commonly produce the wrong answer.
Frameworks are useful precisely because investing decisions repeat. The investor with a written framework makes the next decision faster and more consistently than the investor improvising each time.
Worked example
We walk through a representative situation that most private investors will recognise, applying the framework step by step. The numbers are illustrative, but the structure is real and reusable.
If the example does not match your situation exactly, the framework still applies — that is the point of a framework over a recipe.
Where this interacts with tax and structure
Every allocation decision has a tax shadow. The same dollar of return is worth meaningfully different amounts depending on residency, structure, and the asset class generating it. We highlight the tax interactions that change the right answer.
Investors who optimise on pre-tax return without modelling structure routinely leave 100–300 bps of net IRR on the table per year. Over a decade, that is the difference between a good and a great outcome.
