The Portfolio Selection Solver software (PSSolver) developed by Luis F. Copertari, helps investors (either corporations or individuals) to decide which stocks to invest in using historical stock prices and volume obtained on-line from Yahoo Finance. It is based on decades of careful research and testing. It allows decision makers to select the “optimal” portfolio and/or browse through the data using not only number crunching output but also a tested Graphic User Interface (GUI) for portfolio selection purposes. Hedging is also possible. You can choose any currency for your data and convert between currencies. PSSolver is free of charge and the user’s manual (PSSolver.pdf) can be downloaded here. If you plan to create your own portfolios you will need to download and install Anaconda2. Then you will need to download and install Portfolio Creator (PC). The PC user’s manual can be downloaded here. You can contact us by e-mail at firstname.lastname@example.org.
