Mostly prior-free asset allocation

Sylvain Chassang

    Research output: Contribution to journalArticlepeer-review


    This paper develops a prior-free version of Harry Markowitz’s efficient portfolio theory, which allows the decision maker to express their preferences with regard to risk and reward, even though they are unable to express a prior over potentially nonstationary returns. The corresponding optimal allocation strategies are admissible and interior, and they exhibit a form of momentum. Empirically, prior-free efficient allocation strategies successfully exploit the time-varying risk premiums present in historical returns.
