(Updates from 10:37 a.m. ET with closing information.) NEW YORK ( TheStreet) -- Here's what Jim Cramer had to say on CNBC's "Squawk on the Street" Wednesday. Cramer said investors should not worry about Genworth Financial ( GNW) because the stock is a buy for the second half of 2013. GNW fell 2.8% to $12.99. Waste Management ( WM) is "getting with the program," Cramer said. The company installed its 50th natural gas station as part of a continued move to alternative fuels, he added. WM rose nearly 1% to $42.03. Symantec ( SYMC) beat top- and bottom-line estimates and is moving higher. Cramer praised the management and quick strategy implementation. SYMC was 9.6% higher at $26.68. Questcor Pharmaceuticals ( QCOR) had a lot of short-sellers but was able to beat earnings, causing the stock to shoot higher. Cramer said he wished he'd stayed in it. QCOR soared by 28.4% to $66.66. According to Cramer, Agco Corp. ( AGCO) "is doing better than Deere ( DE)," and money for farming is going to go somewhere now that fertilizer prices have been crushed. Agco rose 2.5% to $56.25. Morgan Stanley downgraded Chart Industries ( GTLS). Cramer said that's a mistake, citing the company as the only true natural-gas play because its equipment is a necessity for converting natural gas to a usable fuel. GTLS rose 1.2% to close at $113.70. To sign up for Jim Cramer's free Booyah! newsletter, with all of his latest articles and videos, please click here. -- Written by Bret Kenwell in Petoskey, Mich.
