"Project management firm Hill International (NYSE: HIL) is one of the best ways to profit from the public works projects planned in government stimulus packages," says Dave Dyer.

In his The Dave Dyer Newsletter, he explains, "HIL is a consulting company that provides expertise in the project management area. Their business is a people business, not a business that requires them to invest in a lot of heavy construction equipment.

"I think this gives them three advantages: first, they do not have the long marketing cycle that can last for years on a large project, second, they have greater flexibility to expand or contract as business opportunities change, and third, their fee-based revenue structure is less risky than other compensation models used in the construction industry.

"HIL has two divisions. Its original business, founded in 1976, was a construction litigation support company that supplied expert witnesses and other expertise to construction companies involved in contract disputes.

"They saw early in their history that they could also provide value as a dispute preventer rather than just an after the fact resolver, so they started a project management division.

"Since the market started its downturn early this year, I have avoided all financial stocks and resisted the temptation of value plays," says Dave Dyer.

In his Dave Dyer's Newsletter, he explains, "Well, it is now time to violate both of those prohibitions at once." Here, he looks at a new buy for SLM Corporation (NYSE: SLM), commonly known as Sallie Mae, the nation's largest provider of college loans and savings programs."

"There must be some financial areas that have predictable, growing demand, willing customers who actually have low default rates, and securitization processes that do not involve the type of financial engineering that is only intended to hide risk.

"Well, there is such an area, and it even involves a product that it makes sense to finance since it will actually increase in value over time. I'm talking about student loans.

"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. If you need to dig a really big hole, talk to BUCY.

"A decline in home ownership is good for companies who have apartments to rent," notes The Dave Dyer Newsletter. To benefit from this trend, he looks at Avalon Bay (NYSE: AVB)." Here is his review.

"After a 10 year period of consistent increases from 1995 to 2005, the trend toward increasing home ownership has reversed and is now clearly in decline. The subprime problems and tighter credit policies will only serve to increase the decline.

"One of the easiest ways to invest in this trend is to buy shares in a REIT that owns apartment properties. Avalon Bay (NYSE: AVB.) is a REIT that manages high quality apartment communities in the high barrier-to-entry markets like California, the Pacific Northwest, the Northeast and Mid-Atlantic.

"In some cases, they develop their own properties; in others, they buy and remodel existing apartment complexes. They currently own 182 properties with about 52,000 apartments in total. AVB has 19 more properties under constructions and development rights for another 52.
