Data science is part of investing. Application of advanced investment strategies require some coding skills. Here you will find out the idea of quadratic approach to portfolio optimization and then you can check on our website how to actually apply it in R: • https://www.abiranalytic.com/mv-optim... • Synopsis: • It is very convenient to look at the mean-variance optimization as quadratic programming problem. Traditional approach to portfolio optimization is to maximize the investor’s utility function. In this function risk (corrected with risk-aversion coefficient) is subtracted from the expected portfolio return. • For quadratic utility problems there is the package quadprog in R/RStudio. The function that we need from this package is called solve.qp(). In the function solve.QP () arguments Dmat and dvec describe the function that is to be minimized. Arguments Amat and bvec contain information about the portfolio constraints. Scalar meq controls which constraints are equalities rather than inequalities. Great advantage of this approach is that it allows user to input custom covariance matrix in the argument Dmat. Also it allows to model a lot of assets, which is a limitation to the Solver optimizer in MS Excel. • #investing #r #投資 #rstudio #r #investment #alpha #finance #assetmanagement #assetweights #allocation #risk #return #howto #learn
