Lightning Round: Threshold Pharmaceuticals, Medco Health Solutions, Tempur-Pedic and More

Threshold Pharmaceuticals : Cramer approves this as a speculative part of homegamers' portfolio.

Leucadia National : This name is too hard to understand, therefore the "Mad Money" host does not recommend buying it.

Kodiak Oil & Gas : KOG is a winner, Cramer said. It has tons of oil and he likes it.

Medco Health Solutions : This name is a buy, Cramer said.

Freeport-McMoRan: While this has a "hideous chart," Cramer said he thinks copper demand is going to surprise people. He would buy.

Nice Systems : Security remains a fabulous theme in this market, Cramer said. He likes Nice.

Perfect World : Because this is a Chinese company, Cramer can't endorse it.

Tempur-Pedic : Mattress stocks are "hot as a pistol," Cramer said. Although Tempur-Pedic is pretty inflated, he thinks it is a winner and a big play on housings turn.

When this story was published, Cramer's charitable trust owned Freeport McMoRan.
