NEW YORK (TheStreet) -- Earnings and politics will be two factors driving ETFs this week. Earnings news will impact solar and water ETFs, while a Thailand fund will digest an important court decision. Meanwhile the movements of a euro ETF will heavily influenced by Europe's efforts to grapple with a deepening sovereign debt crisis.

Claymore/MAC Global Solar (TAN) - Get Invesco Solar ETF Report

This fund declined again last week and this sector has failed to stabilize along with the broader market. It made a death cross on Friday, with the 50-day moving average falling below the 200-day moving average. Exposure to government-supported demand in Europe faces a double whammy of a weaker euro and weak government finances.

Solar earnings continue to come in this week with

Suntech Power


, which accounts for 4.7% of TAN, reporting on Thursday. Analysts forecast the company earned 11 cents per share on $467 million in revenue.

also reports, with analysts looking for 48 cents per share on roughly $267 million in revenue. CSIQ accounts for 3.6% of TAN's portfolio.

Last Friday the Thai supreme court ruled that former Prime Minister Thaksin Shinawatra had used his office to benefit his own business and seized two-thirds of his $2.2 billion fortune. The amount he was able to keep was what he had previously declared as personal assets, while the rest had been hidden from government oversight.

The ruling itself is part of a more complex political dispute between his "red shirt" supporters and their "yellow shirt" opponents, and many analysts were expecting violence in the streets.

Instead, the reaction was muted and the stock market gained on the day. Still, there's reason to be concerned about political instability. THD has been a relative outperformer in the region year to date, and if this matter is truly in the past, performance this week should reflect that.

PowerShares Water Resources

(PHO) - Get Invesco Water Resources ETF Report



accounts for 5% of PHO and will report its annual results on Friday. Its water and environmental services divisions provide the bulk of earnings, but the firm was recently awarded a license to operate passenger trains in France.

VE accounts for nearly 10% of the

Market Vectors Environmental Services ETF

(EVX) - Get VanEck Vectors Environmental Services ETF Report

and will have a larger impact there, but the fund has a low trading volume at less than 4,000 shares per day.

iShares Dow Jones U.S. Home Construction

(ITB) - Get iShares U.S. Home Construction ETF Report

This ETF has been outperforming as of late. Over the past three months, the fund has outperformed the

S&P 500 Index

by about 10%, and year to date, it is up more than 7% versus a 1% decline for the S&P 500 Index.

With housing data negative last week as new and existing home sales fell in January, ITB underperformed for the week. The broader market has gone nowhere since early November, but housing was one area that outperformed. A decline here would be a negative portent.

CurrencyShares Euro

(FXE) - Get Invesco CurrencyShares Euro Trust Report

This fund will remain one to watch as long as debt problems are an issue in Europe. Euro weakness helps the U.S. dollar index, and this has negative implications for commodity prices in the short-run, in addition to helping the U.S. markets outperform Europe.

On Friday, Standard & Poor's warned the Spanish government that it could downgrade its credit rating due to the weak economy.
