Rethinking Spartan Motors Spartan Motors (SPAR)

Although he initially rejected a pitch for Spartan Motors made by an IU Kelley School of Business student, Cramer is now bullish after investigating the stock further. Initially, he thought SPAR was mainly involved with recreational vehicles which would be out of favor with rising oil prices. However, Spartan also manufactures emergency vehicles, and since 55% of the nation's firetrucks need replacing, Spartan vehicles will be in demand. In addition, the armed forces require vehicles that will protect soldiers from roadside bombs. Spartan's military motor division recently scored the second largest contract in its history. The company's RV business is doing well, because baby boomers love RVs. While Spartan has a great story, Cramer cautions that this small-cap speculative stock may not be for everyone and to wait for a pullback before buying.

Related: Daniel Andreas Jacome, the student with whom Cramer initially disagreed about Spartan Motors, explains why he thinks the stock is "money in the bank."

Sell Block: WCI Communities (WCI), Simon Property Group (SPG), Hologic (HOLX), Norfolk Southern (NSC), Union Pacific (UNP), Greenbrier Companies (GBX), Coldwater Creek (CWTR), Gilead Sciences (GILD), Celgene (CELG), Altria (MO), Kraft (KFT) Take-Two Interactive (TTWO)

Cramer is "adamant that homebuilders can't be owned" and would sell WCI even though it hasn't moved, along with SPG, which has had a big increase. He would also sell HOLX which is "priced for perfection" but which has been the target of articles suggesting its products are less than perfect. Cramer likes rails as a "happy oligopoly, but given NSC's disappointing guidance, he would swap it for UNP on any strength. Cramer confessed "I deserve to be roasted over hot coals" for recommending GBX as a short-busting play when the stock has had a huge drop. Cramer wants to avoid getting burned again over CWTR and would sell even though it seems to be making a comeback. He thinks upgrades of semiconductors are "insane" and would get rid of the entire sector. Gilead, Cramer's "bio stock of the year" is now too expensive, and he would sell it or swap into Celgene. Now that Altria has spun off Kraft, Cramer would hold onto MO and sell KFT; "American cheese just doesn't turn it's customers into hopeless addicts."Finally, the fact that it is difficult to zero in on what is really wrong with TTWO is the best reason to sell it.

Mad Mail: Deere (DE), Coca-Cola (KO)

Cramer would back up the truck and buy DE because, for the long-term "we are in a secular bull market inf farming" and sees a strong comeback for Deere. Cramer also likes KO because if it's brand turns around in Japan, KO could rise from $50 to $55.
