A risk measure in a portfolio selection problem is linear programming (LP) solvable, if
it has a linear formulation when the asset returns are represented by discrete random
variables, , they are defined by their realizations under specified
scenarios. The efficient frontier corresponding to an LP solvable model is a piecewise
linear curve. In this paper we describe a method which realizes and produces a tangency
portfolio as a by-product during...
One-fund theorem states that an efficient portfolio in a Mean-Variance (M-V) portfolio selection problem for a set of some risky assets and a riskless asset can be represented by a combination of a unique risky fund (tangency portfolio) and the riskless asset. In this paper, we introduce a method for which the tangency portfolio can be produced as a corner portfolio. So, the tangency portfolio can be computed easily and fast by any algorithm designed for tracing out the M-V efficient frontier via...
