Stocks discussed in the in-depth session of Jim Cramer’s Mad Money TV program, Thursday, May 11 . Click on a stock ticker for more analysis:

PetroChina Co Ltd. (PTR) - Although few Americans show interest in Chinese stocks, Cramer calls PetroChina a "sleeper stock" and the "Manchurian candidate of oils". This is a huge $200 billion company which, thanks to generous funding from the Chinese government, is able to make a large number of acquisitions. Cramer thinks that PetroChina could replace oil giant, Exxon (XOM) in the near future, and this stock is an inexpensive investment.

Rentech (RTK) - This company has developed its own version of a technical process called Fischer-Tropsch which extracts gas from coal and high temperatures. The US Energy Administration has said that such processes will produce viable diesel or jet fuel at $45 a barrel while producing 42% fewer emissions. Rentech may be the first company in the US to make use of this technology on a grand scale.

Microchiptech (MCHP) CEO Interview: CEO Steve Sanghi, co-author of the book Driving Excellence, which chronicles the success of the Microchip industry, agreed with Cramer that the circuit market is not yet finished, in spite of some dire predicitons. However, when Cramer asked Sanghi about the fact that big screen TVs have been "backed up" and are no longer moving, Sanghi simply said that his company does not rely on one "killer application." Cramer felt that Sanghi was dodging the question, and warned agaisnt buying MCHP.
