SFJ Technologies

Our solutions

We are long-term fundamental investors with a knack for mathematics.

We seek to generate superior returns over time by building a granular fundamental research process around proven investing best practices, and applying that process systematically across entire markets.

Many successful investors share that approach. But at SFJ, we add a particular focus on systematization. We leverage data and sophisticated mathematical modeling to instill better and deeper systematization in the investment process.

But, for us, technology always remains in service of our long term, fundamental value investment philosophy. It’s a means to an end.
