Constrained portfolio optimization
WebAug 2, 2024 · In the early days of Portfolio Theory there were different views about short positions. Some authors modeled short positions as negative and required all weights to add up to 1 (first equation), others (including Markowitz himself) thought this was not realistic (he thought if you have 1 dollar you cannot both buy 1 dollar worth of stock and also short 1 … WebJul 8, 2024 · Riskfolio-Lib is an open source Python library for portfolio optimization made in Peru 🇵🇪.

A portfolio is a set of selected stocks chosen by the investor. Risk is defined by the potential associated lost of some or all the original investment. Returns are the associated gains when the price of the stocks increases beyond the original investment.
