NEW YORK (TheStreet) -- Friday's GDP report is the economic highlight of the week, while earnings announcements and industry reports will have a bearing on these ETFs.

iShares Dow Jones U.S. Home Construction Index (ITB)

Lennar ( LEN) represents 8% of this ETF and it reports earnings before the bell on Wednesday. Analysts are looking for a loss of 30 cents a share, which is up from an expected loss of 46 cents a share three months ago. Estimates for 2010 full year earnings have also moved higher, from a loss of 72 cents a share to a loss of 32 cents a share.

In addition to the earnings news, a report on existing home sales for February will be released on Tuesday and new home sales for the same month will be released Wednesday.

The homebuilder ETF has been strong of late: It matched its 52-week intraday high of $13.93 last Wednesday, while setting a new 52-week closing high on the same day.

SPDR S&P Retail ( XRT)

Best Buy ( BBY) reports Thursday morning for the quarter ending in February, which includes the holiday season and the first two months of this year.

Unlike Lennar, the earnings estimates for Best Buy have pretty much stayed flat, climbing only one cent to $1.79 over the past three months. Analysts are either confident or aiming for the middle. In the past four quarterly reports, Best Buy beat earnings estimates by double digits thrice and missed by double digits once.

Electronics are wants, not needs, and strong earnings here will be a signal that the consumer is still very much alive. Although Best Buy is only 1.3% of XRT, but its report is likely to have a larger indirect effect on the ETF due to a light earnings week.

Currencyshares Euro Trust ( FXE)

The euro/U.S. dollar exchange rate neared its 2010 lows on Friday, positioning the euro for a bounce or a breakdown. Given the overall trend and the situation in Greece, no news is bad news for the euro and down is the most probable direction.

FXE's intraday low this year is $134.32 and the fund is less than 1% from that level. Investors can double down on their anti-euro bets with ProShares UltraShort Euro ( EUO), which delivers two times the daily inverse of the change in the euro/U.S. dollar exchange rate.

United States Natural Gas Fund ( UNG)

This is the fund that keeps on giving -- to the shorts. Natural gas has conspicuously slid to new low after new low, despite a broad rise in other energy and commodity prices over the past year and daily new highs for many equities.

UNG has suffered an almost uninterrupted decline since July 2008, and a bottom is still waiting to be discovered. Last week's dip was caused by the arrival of spring weather in the Northeast and other parts of the country. Storage did decline slightly, but inventory remains above the five-year average.

iShares MSCI Israel ( EIG)

Bank Hapoalim, one of the largest banks in Israel, reports earnings on Thursday. It accounts for 4.8% of EIS. The bank can shed some light on the country's economic situation, which looks quite positive. Israel's economy didn't need to rebound much from its mild recession. A clear sign of its relative strength compared to other economies is consumer confidence in the country, which is at a 10-year high.

Also in play is the aftermath from the Teva Pharmaceuticals ( TEVA) buyout of Germany's Ratiopharm last week. The takeover was greeted warmly by investors, who pushed shares up 3.4% on the day of the announcement.

Acquirers typically decline on news of a buyout, but this deal is seen as positive for Teva because it gives the firm a strong position in Germany, which it lacked, as well as solidifies its position in the global generics market after fending off Pfizer's ( PFE) rival bid. Because Teva makes up 24% of EIS, it is always an important stock to watch for EIS holders.
