NEW YORK ( TheStreet) -- Tractor Supply ( TSCO)was upgraded today by analysts, and Jim Cramer, during Monday's Stop Trading! segment on CNBC, declared Tractor Supply a buy. On the show, Cramer noted that there is pent-up demand for gardening supplies. Generally when the economy moves into spring, interest increases in Scotts Miracle-Gro ( SMG), but Cramer said Tractor Supply has better momentum. Meanwhile, in what Cramer called a contrarian move, Goldman Sachs upgraded Southwestern Energy ( SWN). Cramer says now is the time to sell natural gas stocks, but thought it was interesting that Goldman has confidence in the country. "Southwestern is the largest pure play that could be acquired or nibbled at," Cramer said. The natural gas driller is like XTO Energy ( XTO), which got a bid from Exxon Mobil ( XOM), Cramer said. "You have to wonder what's going on," Cramer said. On an unrelated note, NYSE Euronext ( NYX) is up 5.3% to $27.78 in afternoon trading. Cramer says the business -- meaning the trading business, of course -- is getting better, and noted that the stock has a good yield. Lastly, Cramer declared Deckers Outdoor ( DECK) to be a good play, as the cold-weather continues and consumers still desire Uggs, Cramer said. "This one is not done going up." -- Reported by Jeanine Poggi in New York. Follow TheStreet.com on Twitter and become a fan on Facebook.
