"Portfolio Management with Safety Criteria in Complete Financial Markets" Jean-Luc Prigent and Salwa Toumi University of Cergy, 33 bd du Port, 95011, Cergy, France Abstract: We examine portfolio asset management under safety constraints that control the probability that the portfolio return falls under a given reference level. We extend previous results of Roy (1952) and Kataoka (1963) that have been proved in a one-period setting to both multiperiod discrete-time and continuous-time models. Basic examples illustrate the results.
