On CAPS, 93% of the 171 members who have rated Great Lakes believe the stock will outperform the S&P 500 going forward. These bulls include helicopterfool and Dynablob.

A few months ago , helicopterfool touched on the tailwinds working in Great Lakes' favor: "Company is leader in dredging harbors. New law requiring deeper US harbors. ... They should benefit."

Over the next five years, in fact, Great Lakes is expected to grow its bottom line at a brisk rate of 20% annually. That's faster than much larger construction and engineering plays such as Fluor (NYSE: FLR) (11%), Jacobs Engineering (NYSE: JEC) (12%), and KBR (NYSE: KBR) (10%).

CAPS member Dynablob elaborates on the Great Lakes bull case:

Changes in legislation will require Harbor Maintenance Trust Fund to distribute surplus funds to pay for domestic dredging projects. Huge need for domestic dredging work because US ports are shallower than international counterparts (and not deep enough for the largest ships). Expanding the Panama Canal (complete 2014) will only further expand need for deepening of US ports. Federally protected industry means that there are few companies that can compete for these projects.
