But while opinions fly, what stocks should you really be looking at this year? Let's ask a billionaire. George Soros made his mark on the financial world in the early 1970s when he and partner Jim Rogers founded the Quantum Fund, a hedge fund with an international bent. Today, the fund, which started with $12 million, has estimated assets under management of $27 billion. Related: Stocks for the Buy-and-Hold Investor And Soros has done well himself. Forbes estimates that the investor is worth $14.2 billion, earning him the No. 14 spot on the magazine's list of the 400 richest Americans. While Soros may not be detailing his investment ideas to the public, his firm's latest SEC filings do give us an idea of what he's buying right now. Here's a look at three of the stocks that Soros and his investment team are bullish on to start 2011, all of which were new positions for Soros in the most recently reported quarter. In the last quarter, Soros' biggest buy wasn't actually a stock. His firm spent $64 million on shares of the iShares Gold Trust ( IAU), an exchange-traded fund whose shares are backed by actual gold bullion held in London, New York and Toronto. To be fair, IAU isn't Soros' first foray into a gold fund; in fact, his firm owns stakes in a number of other gold plays as well (including other gold funds and other investments, such as gold miners). IAU is designed to track the spot price of gold less a management fee, which is paid for by selling off a small portion of the fund's holdings. That said, at 0.25% per year, the fund's expenses are among the lowest of the gold bullion ETFs, which have become incredibly popular over the last few years. Taxes are something you'll want to consider if gold funds look attractive right now. Because this fund invests in bullion, any gains are actually taxed the same as ordinary income.
