Get Access to

Advanced Screening

Ours is the most usable yet powerful stock screener available. You can use your own universe, rank with your multi-factor rank, and run backtests or rolling backtests. Many pre-built screens are available to help you get started.

Ranking

You can easily create multi-factor stock ranking systems and run performance backtests. Each factor can be weighted and ranked against all other stocks in your selected universe or GICS level.

Strategy Simulation

Test your hypothesis by running a realistic strategy simulation. A strategy is specified using an intuitive wizard to set up your money management rules, your universe and ranking, rebalance method, and the buy & sell rules. Once you are satisfied you can launch a live strategy to track real time performance and get buy/sell recommendations.

Go beyond price and visualize historical point-in-time data and trends using our extraordinary Fundamental Charting tool. We offer dozens of pre-built charts, which not only illustrate their powerful capabilities but can be supremely useful as you analyze a stock. Of course, you can also design your own charts using any  fundamental, estimate, technical, industry data, or your own formulas.

Portfolio123 is the best trading and investing tool that I’ve ever seen. It has the best point-in-time data you can get as a retail investor, and the price is a steal.It’s a great tool, run by wonderful people.

Andreas Himmelreich

Easy to use but powerful functions, backtesting & simulations. My results have been very good and could even be better if I would not try to second-guess my model.
