Five-sleeve allocation calculator

Return, risk, real return, a shock scenario and which sleeve drives it.

Interactive: five-sleeve allocationMedium

Weights, expected returns and volatilities are yours to change. The correlation between equities and bonds is the input that matters most — it was negative for two decades and positive in 2022.

Move the equity–bond correlation from 0.2 to 0.6 and watch the diversification benefit shrink without a single weight changing. That move is what 2022 was. The "bad year" line assumes a normal distribution and is therefore the optimistic case — compare it with the shock line beneath, which makes no distributional claim at all.

The idea behind it

This calculator belongs to How to Think About an Allocation, where the mechanism it computes is explained step by step, with the formula, what each input means and where the simple model stops being right. Everything is computed in your browser; nothing you type is sent anywhere.
