NEW YORK ( TheStreet) -- Investors need to challenge their own ideas, Jim Cramer told the viewers of his "Mad Money" TV show Friday. That's why his game plan for next week includes using the latest data to confirm or disprove many of his current investment theses. Cramer said the latest retail sales numbers will be released on Tuesday. He said that while these numbers are interesting in a broad sense, he's focusing on the earnings of electronics giant Best Buy ( BBY). "There's no better test of the consumer than seeing if they're buying stuff they really don't need," said Cramer, adding that's why Best Buy is a great test of whether the back-to-school" shopping season is on track.
Low Price BeneficiariesWith natural gas prices at historic lows, which companies benefit most? Cramer found a whole host of companies that benefit big from the decline of natural gas. Cramer's big a long time proponent of natural gas as a bridge fuel towards clean energy and energy independence. He said that not only is natural gas good for the environment and national security, it's great for the economy as well. By his latest calculations, converting just 250,000 18 wheelers from diesel to natural gas would create a stunning 1.7 million new jobs in the U.S., making everything from pipelines to fueling stations, and providing hundreds of thousands of supporting jobs. But until Congress helps to make this vision a reality, Cramer said there are plenty of other ways to make money from natural gas, including from the companies that use the most of it. He said that just a $1 change in the price of natural gas translates into 31 to 40 cents a share of increased earnings for Dow Chemical ( DOW) for starters. Likewise, a $1 drop in natural gas means 24 cents to 28 cents a share to PPG ( PPG), a stock which Cramer owns for his charitable trust,
Playing the TsunamiFor "Speculation Friday," Cramer continued on his thesis on "mobile Internet tsunami" by saying that the mobile Internet will not be stopped, not even by a sizable shortage of bandwidth. "Phone companies will just have to spend more money on wireless infrastructure," he said. That means more cell towers, more antennas and better connections from the towers to wireline networks. There are only two pure-plays on latter, said Cramer, and they are Harris Stratex Networks ( HSTX) and Ceragon Networks ( CRNT), both tiny, speculative, companies. Both Harris and Ceragon are leaders in manufacturing the microwave radios that remote cell towers use to transmit data back to wireline networks. Cramer said both companies are not only plays on wireless infrastructure in the U.S., but also in China and India, which are making huge investments into their networks as well. Of the two, Cramer leaned towards Harris, which has 12% marketshare here in the U.S., has $2.15 a share in cash on its balance sheet, and derives 33% of its business domestically. Cramer said Ceragon is also an interesting company with an immaculate balance sheet. The company is also a pure play on wireless, deriving 90% of its revenues from the cellular industry. Cramer issued his standard disclaimer for speculative stocks, buy in increments, use limit orders and don't pay too much in after-hours trading.
