Lightning Round: Heckmann, Acme Packet, New Gold and More

Heckmann : Cramer is bullish on this Palm Desert, Calif.-based company, but only as a speculative play. He said it's the only bottled water maker he's recommending right now.

Acme Packet : The "Mad Money" host likes this company's session border controllers offerings, which allow communications companies to talk to each other over the Internet. He called it a "sizzling" hot business that won't go away any time soon.

New Gold : This is a seasonally cool time for gold stocks, so take advantage of it and leg into a gold stock you like, Cramer said. When it comes to gold, he prefers bullion, the SPDR Gold Shares exchange-traded fund and then the miners, and in that order.

Caterpillar : Take this opportunity to buy CAT, Cramer said.

OmniVision Technologies : This technology company's products go into many Apple devices, so Cramer recommends buying OVTI.

Spectrum Pharmaceuticals : The caller told Cramer this was his speculative stock. Cramer said every investor needs at least one spec in their portfolio.

When this story was published, Cramer's charitable trust owned Apple and Caterpillar.
