to the Black–Scholes model, though he was unaware of their work at the time), the sheets told him what each option was truly worth at a particular stock price—and he would buy or sell accordingly to exploit the spread. The system worked." –MBA Jungle Hull left the blackjack tables with $25,000 and took his winnings to the markets—first leasing a seat on the Pacific Stock Exchange, then starting a firm on the Chicago financial exchanges. Business career Hull Trading Company Hull Trading Company 1985–1999 Blair Hull founded Hull Trading Company in 1985 and served as the firm's chairman and CEO. The company was a global leader in the application of computer technology to listed derivatives trading. Hull developed a proprietary and large scale reliable distributed system architecture, providing automatic real-time pricing, risk management, market making and interconnection with automated options, futures and stock exchanges as they became available. Hull's massively scalable software technology was deployed to cover both domestic and international markets as electronic, on-line exchanges became available, while innovative hand-held computer technology was employed at exchanges still requiring execution by floor traders. "The trading room at Hull headquarters looks like NASA mission control. Powerful workstations process streams of financial data, flashing advice to the handhelds carried by Hull traders at the CBOE and the Chicago Board of Trade (CBOT). Different workstations track the firm's risk profile, sending handheld-equipped traders at the Chicago Mercantile Exchange instructions about how to use futures contracts to hedge trades being made at the CBOE and the CBOT. The goal of this remarkable technological firepower is simple: not to take big risks but to find sure things. Hull's computers search the markets for temporary price imperfections, devise transactions to profit from the imperfections, and hedge those bets to protect against other risks. It's a lot like blackjack. "All you need is a mathematical advantage and the controls to ensure that you stay in the game," Hull argues.
