BRK.A) notables like Burlington Northern Santa Fe Rail Railroad. Looking ahead to final months of 2011, Buffett's foresees continued strength. Excluding Berkshire's housing branch, which the investor feels is still facing steep hurdles, Buffett expects many of the largest businesses under his watch will see record, or near-record earnings this year. Given this rosy forecast, it will be interesting to see how Buffett intends to position himself to benefit in the months ahead. With nearly $50 billion in cash sitting on the sidelines, the investor's elephant gun is loaded and ready to fire. Analysts, commentators and Buffet fans have been itching to see when and where he intends to pull the trigger. Although, on a number of occasions Buffett has provided clues as to what he looks for in attractive acquisition targets, attempting to actually pinpoint where he will eventually spend his cash is a difficult task. In a recent report from Bloomberg, over 30 companies were found to share the qualities Buffett has historically looked for in attractive opportunities. These firms run the sector gamut, ranging from spice giant McCormick ( MKC), to oil and gas driller Noble ( NE), to entertainment retailer GameStop ( GME). Companies comprising this list are not confined to U.S. borders, either. Indonesia's Bumi Resources and Norway's Yara International are some of the international names scoring spots as well.

ETFs offer a better alternative for fans of the Nebraska native. Using these products, investors can not only attempt to gain exposure to possible Berkshire acquisition targets, they can also construct a strong, stable portfolio that will perform well in the event that the investor's optimistic forecast plays out.
