Every number says where it came from

Most investing apps tell you what will happen, never where the number came from. DAVI writes under every number which model it used, which data, and as of which day, so you can check it against the statements yourself.

12 models with open formulas and open track records

Every formula is open. Most come from published investing books and research; the exceptions are Nash NCAV, adapted from Graham’s work, and Sector P/E, which uses the industry’s median P/E. We measured each one against real prices and show the weak results next to the strong ones.
