U.S. drug stocks edged higher Monday afternoon as the broader market lost ground, bogged down by worries about upcoming earnings for the U.S. banking industry and reports of auto maker General Motors' plan for a bankruptcy filing.

The Amex Pharmaceutical Index (DRG) inched up to 237.77 while the Amex Biotechnology Index (BTK) crept up 0.3% to 629.11.

The Dow Jones Industrial Average fell about 40 points to 8,041 in afternoon trading.

Abbott Laboratories (ABT) shares broke out of the doldrums, trading up 2% to $44.63. The diversified healthcare group will release its first-quarter financial report Wednesday morning.

Shares of Johnson & Johnson (JNJ) were marginally lower at $51.28. The conglomerate is expected to report moderately lower earnings early Tuesday.

Alkermes Inc. (ALKS) was the notable exception on the biotech side, with shares climbing 4% to $8.82. Analysts at BMO Capital Markets raised their rating on the stock to market perform.

Rosetta Genomics (ROSG) was a leading advancer amongst the small caps. Shares of the firm shot up 21% to $3.35.

Earlier Monday, Rosetta said it has granted U.S. licensing rights to Prometheus Laboratories for three of its new microRNA-based cancer diagnostic tests. In addition to various payments, including royalties on U.S. sales, Prometheus has also agreed to buy an $8 million equity stake in Rosetta, at $4 a share.

The two companies will also be collaborating on the development of two new gastroenterology tests.
