In response to a number of questions we have received, we have uploaded a new page to the site where we explain our overall approach and philosophy.
Please be sure to check out Our Methods page (located in the "About Us" section of the nav-bar).
In summary, we use Graham's overall philosophy with some of Buffett's style and teachings mixed in. We also have developed our own complex computer model to estimate intrinsic value. By using Graham's approach to select suitable companies and our own model to discover undervalued companies, we believe our method will obtain superior gains for us in the market.
