NEW YORK ( TheStreet) -- Next week's trading action may depend on a Chinese interest rate cut, Jim Cramer told his "Mad Money" TV show viewers Friday. He said if the Chinese don't deliver by Sunday, then the second quarter could start out ugly, with less momentum to keep pushing stocks higher. That's why Cramer's game plan for next week's trading was on the cautious side. In addition to a Chinese rate cut, or lack thereof, Cramer said the markets will also be watching the latest German manufacturing numbers. He said that Germany has been the cornerstone of the European economy, and if Germany falters, that will also heavily pressure U.S. markets. For Tuesday, Cramer said the markets will be watching the latest auto and truck sales. If higher gasoline prices are hurting the U.S. economy, Cramer said it will show up on Tuesday. He told viewers that weak truck sales will be especially bad for Cummins ( CMI). Wednesday brings earnings from Monsanto ( MON) and Bed Bath & Beyond ( BBBY). Cramer said he expects good things from both companies and would be a buyer on any weakness from either. Then on Thursday, Cramer will be watching Carmax ( KMX) for another read on the U.S. consumer and higher gas prices. He advised not buying Carmax ahead of the quarter. Cramer was also bullish on Constellation Brands ( STZ) and said that the latest retail sales data will make Gap Stores ( GPS) the stock to watch in the retail group. Finally on Friday, Cramer said it's back to the economy with the latest unemployment numbers being released. Cramer said he expects weakness from the decline in oil and gas drilling, thanks to America's inept energy policy. In the IPO arena, Cramer told viewers to get in on Retail Properties of America, which will begin trading under the ticker RPAI.
