Look at Things Most Investors Wouldn’t Screening Based on Market Cap

Computers Can’t Predict Every Deviation

We don’t do traditional screens and are actually looking for situations in which the publicly available information that a computer can analyze is giving false signals. For example, we bought auto-insurer Progressive [PGR] in 1999 when their earnings looked bad because they were spending heavily on a direct-to-consumer strategy like Geico’s. A computer would see that as a negative earnings trend resulting in a too-high multiple, but it doesn’t know how to judge whether certain spending might generate big returns in the future.
