About this Lab

Markowitz showed that for any given level of risk, exactly one portfolio offers the highest expected return. The set of all such portfolios forms the efficient frontier - a curve in σ vs. E(r) space. Every rational investor should hold a portfolio ON the frontier, never below it. The exact point you choose depends on your risk tolerance.

Methodology

Every Lab is grounded in standard textbook math (Bodie / Kane / Marcus, Fabozzi, Tandelilin). Read the full methodology in the How It Works panel above.
