NEW YORK (TheStreet) - Here are this week's winners and losers.
It will be interesting to see what the new year has in store for this commodity. Investors looking for a safe way to gain a taste for sugar should look to PowerShares DB Agriculture Fund ( DBA). This diversified product sets aside a good portion of its portfolio to the crop. iPath Dow Jones UBS Oil Total Return Subindex ETN ( OIL) -0.16% While natural gas futures-based exchange-traded products shot higher this week, the same could not be said for funds focused on oil prices. Although crude has been on a tear recently, powered by improving sentiment towards the economic recovery, in the final week of 2010 prices took a breather, leading OIL and the United States Oil Fund ( USO) to noticeable losses. Like natural gas, investors would be best off opting for an equity-based approach to this industry. Funds such as the iShares Dow Jones U.S. Oil Equipment & Services Index Fund ( IEZ) and the SPDR S&P Oil & Gas Exploration & Production ETF ( XOP) are two well diversified and stable products to consider. Guggenheim Solar ETF ( TAN) -1.49% The solar energy industry ended the week on a cloudy note, putting an end to volatile year. Although alternative energy remains a closely watched region of the market, investors hoping to try their luck with solar, wind or nuclear need to maintain a close watch on the macroeconomic issues facing various regions of the globe. Solar energy ran into hurdles this year as the European Union attempted to sort out its debt issues. Austerity measures threaten the government subsidies companies rely on to stay lucrative and therefore weigh heavily on the industry. Written by Don Dion in Williamstown, Mass.
