Investors can look forward to a great infrastructure boom in 2009, says Frank Hemsley. All around the world, major public works programs are preparing to come online. Frank says international companies like Caterpillar (NYSE:CAT) and ABB ltd (ADR:ABB) stand to make big gains this year. Investors can also buy into the many sector ETFs related to infrastructure building.

China’s stimulus package proves that the global infrastructure boom is not dead, says Justice Litle. And that’s big news for base metals like copper. These are essential for construction, and will soar as the world attempts to rebuild its economy. That makes strong base metal producers a bargain now.
