Shares of Martin Marietta are down more than 7% over the past month, but many Fools think they're now too cheap to pass up. In fact, Martin Marietta's three-year average return on equity (11.6%) easily tops that of rivals Vulcan (-0.7) and Texas Industries (-2.3%), as well as other construction material stocks like CEMEX (NYSE: CX) (0.9%), Owens Corning (NYSE: OC) (3.0%), and USG (NYSE: USG) (-46.8%).

CAPS member tekennedy expands on the outperform case:

This is a company with competitive advantages (barriers to entry, limited competition as aggregates have a high weight to value ratio) which will benefit directly from inflation. Earnings should be muted in the next few years as earnings are partially dependent on construction but over the long term should outperform. I like [Vulcan] more because I like their strategy better … but [Martin Marietta] is in better financial shape. Both should perform well over time.
