On Monday, Jim Cramer said the decision by Goldman Sachs Group Inc. (NYSE:GS) to upgrade natural gas is incredibly interesting because this may indicate some type of nat gas legislation is coming soon out of Washington.”You don’t make this call, unless you have some conviction,” he said. Cramer told viewers to look at Southwestern Energy Company (NYSE:SWN) because its the largest pure play driller left to be acquired. “The natural gas driller is like XTO Energy Inc. (NYSE:XTO), which got a bid from Exxon Mobil Corporation (NYSE:XOM),” he said. Tractor Supply Company (NASDAQ:TSCO) was upgraded by Piper Jaffray, and Cramer said this stock could have great momentum. He called TSCO a buy and said there is pent-up demand for gardening supplies. Usually that bodes well for The Scotts Miracle-Gro Company (NYSE:SMG), but Cramer said TSCO has better momentum. Moving on to the exchange sector, Cramer pointed out that NYSE Euronext (NYSE:NYX) has a good yield and looks to be breaking out. “If so, the stock will go higher,” he said. Finally, Cramer mentioned that Deckers Outdoor Corporation (NASDAQ:DECK) is a good cold-weather play due to the company’s Ugg product line. “This one is not done going up,” he said.   Join the fastest growing community of small cap investors at Stockhideout.com
