NEW YORK (TheStreet) -- Here's what Jim Cramer had to say on CNBC's "Squawk on the Street" Friday.

Baird raised its price target on Pharmacyclics (PCYC), but Cramer suggested that Johnson & Johnson (JNJ - Get Report) was the safer way to invest in the industry. PCYC jumped 7.2% to $121.46.

Goldman Sachs upgraded Peabody Energy (BTU - Get Report) to buy from hold. Cramer said this stock is a "China play" as well as a play on coal. BTU rose 4% to $20.87.

Credit Suisse said to buy WhiteWave Foods (WWAV) and Cramer agreed, calling it a "really terrific natural-food play." He added that investors shouldn't give up on the industry. WWAV ended the day 4.7% higher at $20.93.

Barclays downgraded United Continental Holdings (UAL - Get Report). Cramer disagreed with the call. When gasoline and jet fuel go down, "you want to buy this," he said, adding Delta Air Lines (DAL - Get Report) is also a good stock. UAL rose 4% to $35.36.

Merrill Lynch downgraded Deere (DE - Get Report) to hold from buy. Cramer said the stock concerns him because of "falling corn prices." DE was unchanged at $81.50.

DRAM pricing is expected to remain strong, which bodes well for Micron (MU - Get Report). Cramer agreed, saying, "This stock goes to $20." MU was 2.2% higher at $18.11.
