In the past year the biggest one month swing in gold price was about a 13% increase from early February to early March. Futures markets were very similar. The only conceivable way they legitimately made an 85% gain in a single month would be through
extremely risky options and day trading and getting
exceptionally lucky that month. If they could average a 5% monthly return they would be literally the best trader in the world, better than every human, supercomputer, or giant firm full of statisticians
and supercomputers.
