Investor

If you're looking to navigate the global markets with the lowest losses and the richest gains, education and research can be two of an investor's best tools - but a peak inside the financial minds of billionaires doesn't hurt, either.

Those looking for another weapon to add to their investment arsenal this week had a chance to see where the market's biggest hitters have been hunting for profits - and where they have scored the biggest gains.

This week marked the third-quarter disclosure of the biggest U.S. investors' holdings, allowing an infrequent glimpse into the stock decisions of some of the most successful money managers.

Warren Buffett, John Paulson and George Soros were some of the big-name investors who made a Form 13F disclosure filing, which the U.S. Securities and Exchange Commission requires of money managers with holdings in excess of $100 million. Forms are due within 45 days of a quarter's end, with current reports covering the quarter that ended Sept. 30.
