U.S. stocks rose on Tuesday as brokerage upgrades for Intel Corp. and Johnson & Johnson helped market indexes bounce back from Monday's losses. Caterpillar Inc. rose 2 percent to $97.02 after the heavy equipment maker said it will increase machinery and engine prices due to rising costs of steel and other raw materials. Pharmaceutical stocks were higher after Europe's Sanofi-Aventis SA, the world's third-largest drug maker, beat expectations with an 18 percent rise in its first year's post-merger net profit. Sanofi-Aventis shares in the U.S. rose 1.7 percent to $40.61. Pfizer Inc. rose 1.3 percent to $26.63. Biogen Idec was up 4.3 percent to $40.33 after Smith Barney raised its ratings on Biogen and Elan Corp. Plc, saying Monday's market reaction to the withdrawal of the multiple sclerosis drug Tysabri was overdone. Smith Barney raised Biogen to "buy" from "hold" and raised Elan to "hold" from "sell." Elan shares in the United States were unchanged at $8. --More 2218 Local Time 1918 GMT
