Jim Cramer said on his "RealMoney" radio show Thursday that PepsiCo ( PEP) is one of his favorite stocks in an uncertain market. "There are very, very few things that I can trust in this market and Pepsi is one of them," he said. Not only is its division Frito Lay doing well, but also the company has the most aggressive buyback of any large companies Cramer said he follows. The stock is not expensive and has room to grow $4 to $5, he said. An analyst downgraded Sirius Satellite Radio ( SIRI) today because of a supply chain risk, Cramer said. The analyst also cut the valuation of the stock from $8 to $4.50 based on this. Cramer said his assessment on the matter is that Sirius is better than XM Satellite Radio ( XMSR). Further, Cramer doesn't believe that there is any near-term catalyst that will move the stock. But if XM Radio and Sirius merge, he believes it could be a home run. Otherwise, Cramer said, you are sitting on dead money as analysts run away from it. Energy stocks and oil drillers are artificially down, and Cramer said he would be a buyer of them. Since January, natural gas has been going down, but in the last five days it has crept back to $5. Therefore, companies that are involved in the natural business should be bought here, he said. Chesapeake ( CHK) and Nabors Industries ( NBR), which he owns for his charitable trust, Action Alerts PLUS , should be bought, he said.
