Netflix also has a rough morning a day after the U.S. markets had their biggest gains in six weeks.

NEW YORK U.S. stocks are in decline Tuesday morning as Johnson & Johnson and Cardinal Health lead health care companies lower and weak trading results from Goldman Sachs drag down bank stocks. Stock indexes in Europe are tumbling after the British government called for a surprise early election next month.

KEEPING SCORE: The Standard & Poor's 500 index shed 4 points, or 0.2 percent, to 2,344 as of 10:10 a.m. Eastern time. The Dow Jones industrial average lost 76 points, or 0.4 percent, to 20,560. Goldman Sachs was responsible for almost all of that loss. The Nasdaq composite fell 7 points, or 0.1 percent, to 5,850. The Russell 2000 index of small-company stocks dipped 3 points, or 0.2 percent, to 1,358.

Stocks are coming off their biggest one-day gain since March 1, when all four major indexes set record highs. They've mostly traded lower since then.

HEALTH CARE WOES: Health care products giant Johnson & Johnson fell after investors were disappointed with its sales. The company's revenue was weaker than expected as sales of its Crohn's disease drug Remicade declined 6 percent. The company also said growth for many consumer health products slowed down and payers demanded bigger rebates on treatments for cardiovascular ailments, diabetes, and other primary care products. Its stock lost $4.05, or 3.2 percent, to $121.67.

Prescription drug distributor Cardinal Health said it will reach the low end of its profit estimates for this year and it projected a smaller profit next year, partly because drug prices continue to fall. The company also said it will pay $6.1 billion to buy Medtronic's patient care, deep vein thrombosis and nutritional insufficiency products businesses. Those products have a combined $2.3 billion in annual sales. Cardinal Health sank $9.40, or 11.5 percent, to $72.43.

BANKS STRUGGLE: Goldman Sachs had a rare miss in its first quarter results, as its typically best-in-class trading desks did not perform as well as its competitors. The financial firm reported a drop in revenue from stock trading and its overall revenue wasn't as good as investors expected. The stock gave up $8.70, or 3.8 percent, to $217.56. It's up more than 35 percent over the last year and reached all-time high above $250 a share in March. Goldman has been a major contributor to the Dow's post-election gains.

WHAT ELSE IS ON? Streaming video company Netflix sagged after it didn't gain as many subscribers in the first quarter as investors hoped. Its second-quarter profit guidance also fell short of analyst estimates. Netflix lost $3.17, or 2.2 percent, to $144.08.
