Nothing like currency action to get the speculation running, or sometimes the other way around. Along the way, a sense of perspective about our dollar's strength and position tends to get lost – or hidden by the odd hedge fund talking its own book.

There are several threads to what the Aussie's been up to this week, ranging from conspiracy theories to Reserve Bank monetary motivations to plain wrong commentary. It was particularly funny to see George Soros' hedge fund and friends trying to talk the Aussie down, and seemingly getting away with it without question.

Do you think a highly professional hedge fund would accidentally leak that it had made a billion-dollar bet against the Aussie? Probably not. Having made such a bet, the fund would have everything to gain by letting it be known. And if a fellow traveller chimes in with a prediction of the Aussie crashing, well, that's extra sauce.

The thing about hedge fund heroes is that you hear plenty about their wins, but not so much about their losses, unless they send the fund broke.
