For the first five months of the year, foreign exchange trades were the largest bet in Caxton's main macro fund, and those trades were making the fund the most money. About half of Caxton's risk was from trading currencies, a higher-than-normal level for the firm that Bruce Kovner, who boasts one of the best track records in the hedge fund industry, formed 27 years ago. Law, who grew up in Cheshire, England, and is based in London, has been with Caxton for seven years. He was named Kovner's heir apparent in 2008.
