I see products by powershare that uses index future to do 2x or 3x leverage, but I don't think it's discussed very much as to how they eliminate the tracking error to the stock index.
If I do the leverage with index future and make up the rest with ETF, I always get tracking errors and even if I multiply it with beta.
