A long time ago the Internet was a bubble. After the gut wrenching internet roller coaster of 2001,
I decided that I needed a more systematic approach to investing. A powerful, mechanical system that combined technicals
and fundamentals, easily configurable, and that could be tested faithfully historically.
...but Portfolio123 makes investing easy...
Portfolio123's institutional-quality tools allow you to prototype, simulate, and launch a strategy.
With a complete set of fundamental and technical functions, Portfolio123 allows you to create an infinite
number of systems. Once a system is launched, the portfolio is evaluated consistently and accurately at
every rebalance point. Managing a portfolio becomes as simple as following the buy and sell recommendations.
...with the best quality data...
Do you know why Benjamin Graham is still relevant today? Have you ever wondered why great simulated returns fizzle
once you start investing? The answer to these questions is data. Portfolio123 has the best historical
data and engine you can find. With quality data a good system like Ben Graham's shows great simulated results that hold up in time.
This is not a coincidence.
...uncompromising attention to details...
Our historical ratio engine is nothing short of magical. By using Compustat Snapshot data with item by
item effective dates, we can accurately re-create the past. We take everything into account: dividends,
pre-announcements with sparse data, spinoffs, deep data coverage, dead-companies, historically correct taxonomies and universes.
And we make all this available instantly, with blazingly fast simulations.
Itís no wonder that Portfolio123 was selected for use by many MBA courses.
...and a free trial.
