He said the bullish train is leaving the station, and the time to get on board is now.Cramer said with so much good news on Wall Street, it's time for some new rules. Rule No. 1: Don't fear the Democrats. Cramer said President Obama hit the road again today with a pro-business agenda and rhetoric that Wall Street loves. There may be compromise on middle class tax cuts, and compromises on other pro-business proposals, he said. Rule No. 2: There's less banking uncertainty. Cramer said newly announced financial regulations in Europe won't kick in for years, and many of the European banks have already raised a tons of capital, both of which are good news for banks worldwide. Rule No. 3 - Europe Is open For business. Cramer said the latest estimates for growth in Europe are twice what was feared. This is great news for companies like Boeing (BA) and Honeywell (HON). Rule No. 4: China's ready to leap forward. Cramer said the so-called "soft landing" in China is happening, and China is once again heading for double digit GDP growth. Growth in China means great things for Las Vegas Sands (LVS) and Wynn Resorts (WYNN), which bet big on Chinese gambling, and for the big engineering companies like Bucyrus (BUCY) and Joy Global (JOYG). "Look out above," said Cramer, the bulls are coming.
