Since 2011 this is my main modeling platform - no regrets I have been using this platform since 2011. I have used others, even ones that cost 6-digits per year to license and I can honestly say I prefer this one. I have used ClariFI and WorldQuant to name just 2 of the high institutional grade platforms and about 6 others. The P123 simulation engines are lighting fast, they listen to users and are always adding new features...in fact...after 9 years of using the platform I still probably use only 20% of what it can do. A well-rounded system whether you are running simple screens, custom weighed complex portfolios or in-depth research. Any serious family office or smaller firm should take the time to get one of their guys trained on this platform.

More Fun Than Video Games! I Joined P123 Apr 28, 2004, and I have been Investing in systems I developed ever sense then. I currently am receiving 60% of my family annual income from my investments. P123 is more fun than video games! I LOVE it! Denny Halwes

I really like P123 works I really like P123 works. The criteria for screens are easy to create and change. It's not a dumbed down version like I've seen on other sites. The backtesting is an interesting and useful feature. To get a 5 star rating you would need to (1) change FCF to exclude dividends (that is so weird and causes me more work to get around), (2) add Invested Capital as a criteria in screening (this would also save me a lot of work), and add foreign stocks to screening universe (I wish you luck in this endeavor. At this point I cannot contribute.)

Great 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.

Extremely powerful tool Extremely powerful tool. I have been using it for almost two decades. There is nothing else like it available to the general public. I have gotten great results.
