I bet the top one is a "geared" fund or a Chinese share fund. For last year it got to be one of them to perform that good. Unfurtunely history want repeat. Last year’s winner is no necessary this year’s winner.
You can use a margin lending facility to amplify your investment portfolio pretty much the same way u borrow money to buy a property.
You can for instance borrow up to 75% leverage for anz, bhp etc. and hips of investment fund.
Anz, St George and other market players (12 or so) all offer margin lending products.
