Over on CAPS, fully 369 of 372 (99%) of the All-Star players who have rated POSCO believe the stock will outperform the S&P 500 going forward. These All-Star bulls include NetscribesManufac and Ayax2006, both of whom are ranked in the top 10% of our community.

Last year, NetscribesManufac noted that POSCO is "one of the lowest-cost steel producers in the world and benefits from having some of the most technologically advanced mills, a labor force that works six days a week, captive power plants and port facilities." That helps it post high operating margins relative to its peers.

A more recent pitch from this spring, written by Ayax2006, shares that bullish logic, while touching on the stock's present valuation:

Korean steel producer trading at attractive value. The firm has good growth prospects, it sells its products at lower prices than competitors and should be able to gain market share, as well as raise its prices. This also provides downside protection in case commodity prices come down. Demand for steel will continue to be strong as emerging markets catch up and countries keep investing in infrastructure.
