"One of my favorite was to play the market is to find a hot area and then invest in companies that provide products to support that market," says Dave Dyer.

In The Dave Dyer Newsletter he explains, "Bucyrus International (NASDAQ: BUCY) is a domestic heavy equipment manufacturer that is focused exactly in the areas that will benefit from the global commodities boom.

"The company's products are focused on mining for coal, iron ore, copper, oil sands, and other minerals needed to support the global infrastructure expansion. Mining is hot right now, and all mines need mining equipment. "Rapid industrial expansion in Asia and Eastern Europe requires raw materials. This trend is not likely to stop soon.

"BUCY is a very old company. In 1880, they started as a small foundry in Bucyrus, Ohio. By 1904, they were supplying excavation equipment for one of the largest projects in the world, the Panama Canal. By 1969, they were making earth moving equipment that was almost 22 stories tall.
