CAI started using portfolio123 around 19… I started using portfolio123 around 19 years ago. Simply the best product for quantitative stock analysis. No other come even close. The only solution you need for your stock investment assuming you have the time and desire to learn factor investing.

FRGreat Tool Great Tool, great team, great support. I am a very satisfied user for 9 years. I have spent countless hours on it. Only concern: their are dependent on data providers policies. It may occasionally result in changing data or pricing. Backtest servers are much faster and more reliable than in 2 other similar platforms I have tried.

GBFantastic product for individual investors If you like data driven investing and are willing to do the work, Portfolo123 provides all the information you need to construct and trade investment strategies. I've been a client for about 10 years and, for fundamental investing, I haven't found any site that comes close. You can write your own formulas to interpret the data, weight stocks in your portfolio, use your own buy and sell rules, trade weekly, monthly, or however often you think appropriate. You can test your strategies on data going back many years, and they provide articles and a forum for exchange of information to help you learn about factor investing and how to use their site. I wouldn't go anywhere else to manage my money.
