Portfolio generating functions

WebIn this paper we develop a concrete and fully implementable approach to the optimization of functionally generated portfolios in stochastic portfolio theory. The main idea is to optimize over a family of rank-based portfolios parameterized by an exponentially concave function on the unit interval. WebThe concept of “functionally generated portfolios” was introduced by Fernholz [9, 11] and has been one of the essential components of stochastic portfolio theory; see Fernholz and Karatzas [] for an overview.Portfolios generated by appropriate functions of the individual companies’ market weights have wealth dynamics which can be expressed solely in terms …

WebThe below function is generating a random portfolio, obtaining the returns, volatility, and weights. We'll also go ahead and add an annotation showing the maximum Sharpe ratio (the average return earned in excess of the risk-free rate per unit of volatility or total risk). In general, a higher Sharpe ratio is better.
