WHEN he was 12, Warwick Bartlett bought “100 Famous Greyhound Systems”, a guide for betting on dog races. After spending a year tracking every stratagem and picking the best two, he went to the races to take his first punts. He lost. Mr Bartlett, now the boss of GBGC, a betting consultancy, says it taught him a good lesson: “A system can win for a period of time. And then it’s had its day.”
Two trading companies are trying to prove him wrong. Melbourne-based Priomha Capital, which claims to be the “world’s premier sports hedge fund”, wagers on European football, cricket and golf. Founded in 2010, the firm manages about $20m. Stratagem, a rival based in Britain that styles itself as a technology business, wants to raise $25m from rich individuals.
