This past week, Jim Cramer was focused on the market’s strength, explaining both his reasoning for it and what it meant to both longs and his friends who unfortunately have been short. Despite this move, Jim still sees certain areas of the market where there are very good, cheap stocks. He talked about fear and tight supply being reasons behind the market’s direction but said anyway you see it, now is time to “bow to the breakout.” Here are some the highlights from Jim over the last week (aggregated from Mad Money, Stop Trading! and his articles):

Cramer’s Private Equity Plays: On the 4-23-07 Mad Money show, Cramer pointed out that private-equity firms are making "crate loads of money.” So Cramer figured it was time other people got in on the action. He said the goal was for investors to figure out what the private-equity folks are going to buy tomorrow. With that goal in mind along with some help from a Goldman Sachs report on private equity targets, he gave us his Private Equity Plays. His picks include ATU and DRI.

Cramer’s Bullish Plays: On the 4-24-07 Mad Money show, Cramer came out swinging with the DJIA over 13,000 calling for a "1,000 point rally" by summer's end. He thinks this is a conservative forecast and retail has not even been in the market yet. He went back to one of his favorite themes, pointing out that buybacks are eating up supply and killing shorts in the process. Making that kind of call certainly meant that Cramer was going to give us some names so we could ride with the bulls and he didn’t disappoint as he mentioned his Top Bullish Plays for us to follow including CAT, RIG and HON.

Jim also went back to two recent investment themes in recommending how to join this market move by saying we could jump on his Green Day Plays or his Benefit of the Doubt Plays. Some of these picks include SHLD, FD, FTEK and WFR.

Cramer’s Steel Plays: Cramer pointed out this week that "we are witnessing a miraculous re-valuation of the steel stocks, one that is, quite frankly, breathtaking in its breadth. The reasoning is threefold: takeovers, which continue unabated globally; demand from China, which seems almost endless, the way it was for this nation in the early 1900s; and low valuations. Cramer was all over it and gave us his Favorite Steel Plays. Some of the names Cramer is watching include RS and X.

Cramer’s Rail Plays: Cramer informed us that the four big rails are "flush with cash" on his Mad Money show on 4-24-07. Cramer said they are going to be buying a lot of equipment and offered us his Rail Plays. He pointed out that the Railway Tie Association expects that 21 million railroad ties will be sold this year - a lot more than usual. And low supply and high demand means higher prices. Some of his picks included GBX and TRN.

Cramer’s New Management Plays : On the 4-25-07 Mad Money show, Cramer told us that "every so often a new CEO comes into a company and makes an immediate difference." It's rarer when this happens with a "behemoth," and rarer still when it happens to two behemoths at once. As a result, Cramer told us to buy these New Management Plays.

Cramer’s Grocery Chains: Cramer has always liked attending conferences because there was a chance he would stumble into a good story about a good company he didn't know beforehand. A few weeks ago he went to the Bank of America conference to speak and stumbled into the Supervalu presentation. He hadn't looked at it for years and came away liking it. "We tend not to think there's that much growth in this sleepy industry. That's wrong." Thus, he concluded by disclosing his Favorite Grocery Chain Plays. They include KR.

Lightning Round: Cramer was full speed ahead last night with his latest Lightning Round. He was bullish on several stocks such as ADM and T but also bearish on the likes of AKAM and MRVL.
