Analysts surveyed by Thomson Reuters expect First Solar Inc. (NASDAQ: FSLR) to report first-quarter earnings of $1.51 per share, which is 62.3% higher than a year ago. Revenue for the quarter is expected to be 105.6% higher, or $404.9 million. First Solar earnings have topped expectations in the past five quarters, by as much as 47.3%. The long-term EPS growth forecast is 40.6% and the forward PE ratio estimate is 23.0. In the previous quarter, Tempe, Ariz.-based First Solar reported having more cash on hand than debt. The First Call consensus recommendation is to buy FSLR; CNBC recently included it as a stock pick. First Solar has announced that it will build new solar power plants in Nevada and Germany. Its share price has risen 6.9% since the beginning of the year to $147.46.

"Although I am not a big fan of either technology stocks or Chinese stocks, bear markets do create opportunities -- such as Sohu.com. (NASDAQ: SOHU), says Jack Adamo.

In his Jack Adamo's Insiders Plus newsletter, the advisor reviews Sohu.com, the second-largest internet search engine company in China.

"In recent quarters, it has made 42% of its revenues from search and display advertising; the rest comes from online gaming and wireless services. Earnings in the September quarter grew by more than fourfold year-over-year.

"With the Olympics over and the economy slowing to an expected GDP rate of 7%, earnings growth at Sohu is expected to slow as well. The last few quarters bear that out. But even in the slowing environment, earnings were up 14% compared to the June quarter.

"For a Chinese stock, this may be considered to be a relatively slow grower, but the price is right. Selling at less than 10-times earnings, you'd be hard pressed to find a better buy among well-established Chinese companies.

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.
