I have already merged R − r f in a single variable which is the Excess Return, the resulting Ratio being: R + σ. The program would take this form: arg min x u x x Σ x ′ s.t. ∑ w i = 1 where both u (mean) and Σ (var-covar matrix) are the first two ...

Webb13 juli 2024 · In order to speed up optimization, the algorithm here uses multiple learning rates, as described in the above steps. It starts with a bigger learning rate. If the algorithm finds a better Sharpe ratio, it will continue to search with the current learning rate. Otherwise, the learning rate is halved.
