Lightning Round: Apple, Celgene, Bank of America and More

Geron : “Much too speculative,” Cramer said. Investors should sell GERN and buy Gilead Sciences , or Celgene on any pullback.

ARM Holdings : Cramer is bullish on ARM, a play on, among other things, mobile Internet. He also reiterated his call on Apple , his favorite smartphone maker right now, saying the stock should be bought at this level.

Bank of America : “Huge upside,” Cramer said of BAC. He urged viewers to buy the stock and predicted it could jump to $18 from $13.

Starent Networks : Cramer called STAR “absolutely terrific.” Buy Starent Networks, he said.

CKX : “Too hard for me to value,” Cramer said. Don’t buy CKXE.

Thompson Creek Metals : Take profits, Cramer said. Freeport-McMoRan’s CEO recently said he was still concerned about the molybdenum market, TC’s business. Investors should lock in gains while they have them.

Cramer's charitable trust owns Gilead Sciences.
