NEW YORK ( TheStreet) - Here are five ETFs you should watch this week.Market Vectors Rare Earth/Strategic Metals ETF ( REMX) Rare earth metals stole headlines last week after news that China was planning to pare back its export quotas in 2011. This industry has become exciting to watch and REMX has had little trouble gathering an impressive following. Although it is only two months old, the fund already boasts an average trading volume of more than 400,000. Rare earth metals will likely become increasingly more important in the foreseeable future because they are used extensively to produce various components needed to power smartphones and other handheld gadgets. Risk tolerant investors may find REMX an exciting product in the new year. Market Vectors Agribusiness ETF ( MOO) The agriculture industry enjoyed an impressive performance in the past six months as investors attempted to position themselves to take advantage of the increasing food demand from emerging markets. This is a trend which I see continuing in the start of 2011. Investors looking for the most conservative agriculture pure play should turn to MOO. Unlike other products which are backed by futures contracts, MOO tracks a collection of companies which are heavily involved in the industry. This week, two notable holdings, Mosaic ( MOS) and Monsanto ( MON) will release their quarterly earnings reports. Their performance over the past three months will likely play an important role in directing MOO's action for the week. iShares Dow Jones Transportation Average Index Fund ( IYT) The transports look prepared to start out 2011 on a strong note and IYT is the best way to access them. Last week, investors received optimistic news regarding e-commerce numbers. As a result of the winter storm which battered the Northeast, many snowed-in shoppers turned to their computers to get their post-holiday shopping done. This news bodes well for big name delivery services including FedEx ( FDX) and UPS ( UPS). The airlines were offered some promising words as well. Although winter weather has weighed on the industry throughout the last week, Delta ( DAL) said Friday that most of the firm's operations are back to normal. ETFS Physical Palladium Shares ( PALL) Investors will be greeted to a bevy of economic data points this week including auto and truck sales numbers. These reports will influence the price performance of platinum and palladium as the two white metals are essential ingredients in the production of catalytic converters.
