Since its inception in 1987, the Susquehanna International Group of Companies (SIG)* has grown from a trading firm on the Philadelphia Stock Exchange to one of the largest privately held financial institutions in the world. With more than 1,500 employees worldwide, SIG sits at the helm of the latest trends and developments in trading and market making, institutional sales, research, private equity, venture capital, and investment banking. SIG has offices across North America, Europe, Asia, and Australia.

SIG distinguishes itself through its global market presence, capital commitment, and its grasp of trading dynamics. It excels at decision theory and implementing sophisticated pricing probability models. 
 
The SIG Philosophy
Our distinction lies in our approach to problem solving - a process guided by the tenets of decision theory and probability. Every choice we make, whether it is developing a new business line, executing a particularly challenging transaction, or bringing new members of the SIG team on board, is done with an eye keen to how that decision affects our overall growth strategy. We believe that our most successful endeavors depend on how well our choices fit together. Our sound decision-making acumen in uncertain environments gives us a substantial intellectual and analytical edge in the global marketplace.
