On tonight's MAD MONEY on CNBC, BASF (NYSE: BF) in Germany is the next stock that Cramer wants to visit as an EU play, and he also thinks this company will be making some acquisitions. He does not see this as the traditional takeover stock. This one did the $80 to $120 move already, and this is over $60 Billion in market cap and he wouldn't be shocked if it goes to $150.00. He noted it is also cheaper on P/E than Dow Chemical (NYSE: DOW) and it only gets 22% of its net from North America. BASF's earnings are also becoming more and more consistent, and that can command a P/E premium from Wall Street.

Interestingly enough, Cramer also gave us a chemical stock that could be an acquisition target. We already say Lyondell Chemical (NYSE: LYO) fall to Basell, and Cramer thinks that Nova Chemicals (NYSE: NCX) is the other chemical stock that could easily be acquired. The analyst at BB&T has picked the last two buyouts in the sector and he thinks Nova Chemical could be the next target. This one has a $3.3 Billion market cap and is atthe top of its 52-week trading range. It is far under the $50.00+ highs of early 2005.

BASF is definitely a company to watch, although Cramer is probably right that it won't be acquired. We are back to a good solid manufacturing economy and emerging markets are helping all these guys out. The company has managed to be a growth engine, and if it is true that their earnings are becoming more predictable then maybe he's right. Nova is a tough one to call, particularly since I haven't looked at it closely in some time.
