NEW YORK ( TheStreet) -- Here are five ETFs to watch this week.Market Vectors Nuclear ETF ( NLR) Washington faced a substantial shake-up during last week's mid-term elections. There will be no downtime for these newly elected legislators, as the debate over energy reform kicks off. With Republicans leading the House of Representatives, political analysts predict that nuclear energy will receive some welcomed attention. ETF investors looking to gain access to this industry should look to NLR. Although Washington debate will play a part in shaping the outlook for nuclear energy, investors should keep an eye on earnings this week as well. Industry leader Cameco ( CCJ) is scheduled to report its quarterly earnings report early on Monday. CCJ is NLR's largest position, accounting for nearly 10% of its total portfolio. SPDR S&P Retail ETF ( XRT) Earnings season will play a big part in directing the performance of the retail industry this week. XRT index constituents such as Macy's ( M), JCPenney ( JCP), Advance Auto Parts ( AAP) and Priceline ( PCLN) are all scheduled to report their quarterly performance. Also, though not listed among XRT's holdings, Polo Ralph Lauren ( RL) is also scheduled to release its earnings report. This firm's performance will likely provide some indication as to how teen and mid-range retailers will perform this week. The consumer looks like a promising facet of the market as the global economy continues to heal and we prepare for the upcoming holiday gift giving season. Investors can use funds including XRT and PowerShares Dynamic Food & Beverage Portfolio ( PBJ) to access the consumer's recovery. Market Vectors Indonesia ETF ( IDX) The emerging markets continue to prove promising as investors seek out investing opportunities beyond the shores of the United States. Last week, in attempts to fend off inflation resulting from this rampant interest, nations including Vietnam and India raised interest rates. While countries such as Vietnam and India appear promising, not every corner of the emerging market world is as rosy. Indonesia, in particular, could be in for a rocky ride in coming days as the nation faces continuing threat of natural disaster. Since the end of October, Mount Merapi has been erupting, threatening villages and taking lives. So far, the eruptions have had little effect on IDX's performance. Still, I would advise investors to use extreme caution when venturing into the fund in the near future. iShares Gold Trust ( IAU) Precious metal ETFs scored impressive gains in light of last week's policy statement from the Federal Reserve, leading physical backed-gold funds like IAU back to previous all time highs. Gold has been an attractive source of protection against market uncertainty and will likely remain strong next week as well.
