On CAPS, 97% of the 930 members who have rated POSCO believe the stock will outperform the S&P 500 going forward. These bulls include athenamike and Simbalion200.

A few months ago, athenamike reminded Fools that POSCO "is one of the most efficient steel manufacturers in the world, especially in higher end products like stainless steel." Our CAPS member concludes: "Added to this, its geographic location and future expansion plans allow for continued growth for many years to come."

POSCO's low-cost operations and high exposure to emerging markets continue to drive its five-star CAPS status. In fact, POSCO's laser-like focus on efficiency has translated into historically higher operating margins than formidable steel foes ArcelorMittal, U.S. Steel, and Nucor. And with Berkshire Hathaway's (NYSE: BRK-A)(NYSE: BRK-B) 4.5% stake in the company, POSCO bulls can rest assured that Warren Buffett, himself, stands ready to oppose any questionable acquisitions.

CAPS member Simbalion200 sums it up:

The company makes hot- and cold-rolled steel products (plate steel, stainless steel, electrical steel, and wire rods), which it sells to the auto and shipbuilding industries. It produces more than 30 million tons of steel a year, making it the world's No. 3 steelmaker behind the combined ArcelorMittal and Nippon Steel. ... The South Korean government privatized its stake in POSCO in 2001, ending the company's 30-year steelmaking monopoly. ... Very profitable company with significant upside. Stock should outperform the market.
