They added that the fund had about a negative 2% performance for the year to the end of October.
The CGI fund, at the end of June had been down about 8%, added one of the sources.
The CGI fund did well from a view that the Bank of Japan would ease its ultra-loose monetary policy, said two of the sources.
They also said short bets that bond prices would fall, as well as bets the U.S. Treasury yield curve would steepen were some of the top earners for the fund.
Caxton's CGI fund also profited from the difference between Japanese and U.S. stock prices, the sources said, adding that losses on commodities bets in gold and a yen hedge detracted from performance.
