"My pick for the top stock of 2010 is Gafisa (GFA), a Brazilian homebuilder and developer," says emerging markets specialist Paul Goodwin.

In his The Cabot China & Emerging Markets Report, he explains, "This is an experienced growth company in a country with an excellent economic engine."

"Gafisa S.A. (NYSE: GFA) is a bet on Brazil; the company is the country's second-largest homebuilder," says international investing expert Nicholas Vardy.

In his The Global Bull Market Alert, he adds, "Brazilian homebuilders are a red-hot sector in a red-hot market. Brazil is one of the strongest-performing global markets this year, and one that you should definitely have exposure to in the final quarter of 2009.

"Brazilian homebuilders are a red-hot sector in a red-hot market. Stocks in this sector have already doubled their share prices this year as policy makers cut interest rates to a record low and the government unveiled a 34 billion real ($18.8 billion) housing stimulus plan.

Q. Emerging markets have been beaten up and the Russia/Georgia conflict, unfortunately, points out one of the problems with investing internationally -- uncertainty created by government and political actions. How can investors protect their portfolios?

A. Every investor should follow the usual advice -- diversify your portfolio among different asset classes, including bonds, value stocks, income stocks, and growth stocks. Avoid overexposure to any one sector or industry, no matter how hot.

But we follow two additional important rules: 1) Use a strict loss limit of 15% (in difficult markets) or 20% (in supportive markets); and 2) always be prepared to exit the equity markets and go to cash when the general trend of the market is against you.

Readers of this space know that the investment bias is toward large-cap companies with demonstrated business models and a competitive advantage in established markets, preferably with a favorable global trend for support. But every once in while an exception is made for a non-conforming but innovative and promising company, and along these lines Gafisa S.A. looks attractive.

Gafisa S.A. (NYSE: GFA) constructs residential buildings in middle/upper income areas in 35 markets in Brazil. Analysts like Gafisa's huge inventory of land, construction in progress, and finished units, all of which will serve to increase earnings, moving forward.

Further, outstanding mortgage loans in Brazil are only 2% of GDP. That means there's room for the nation's mortgage-based home buyer segment to expand. Meanwhile, lower interest rates in Brazil are providing a tailwind for the nascent, local mortgage market. The First Call F2007/F2008 EPS consensus estimates for GFA are $1.38/$4.18.
