FOX Business: Capitalism Lives Here

Heavy selling across the financial and consumer discretionary sectors sent U.S. stock-market indexes stumbling deep into the red.

Today's Markets

As of 3:14 p.m. ET, the Dow Jones Industrial Average fell 103 points, or 0.62%, to 16427, the S&P 500 slumped 13.2 points, or 0.7%, to 1871 and the Nasdaq Composite fell 45.3 points, or 1.1%, to 4093.

After a quiet start, Wall Street headed south in afternoon trading. The financial and consumer discretionary sectors were the worst performers. In a somewhat unusual move, the energy sector, which usually falls with cyclical stocks, was actually one of two advancers. Utilities, which are seen as a safe haven because of their dividend yields, also climbed. 

The pace of mergers and acquisitions in the health-care space continues heating up. Merck (MRK) said it will sell its consumer care unit to German Bayer for $14.2 billion. This comes as Pfizer (PFE) is pursuing a $106 billion buyout of AstraZeneca (AZN) and Valeant (VRX) is attempting to buy botox-maker Allergan (AGN). 

Elsewhere in corporate news, insurance giant American International Group (AIG) saw its shares slump after posting a 27% drop in first-quarter profits. Twitter (TWTR) shares plunged to new lows as the lock-up expires in the micro-blogging site's stock.

On the economic front, traders will get a look at U.S. international trade at 8:30 a.m. ET. The trade deficit is forecast to have narrowed to $40.3 billion in March from $42.3 billion the month prior. While the data are a lagging indictor, they figure directly into broader economic calculations.

U.S. crude oil futures rose by a penny, or 0.01%, to $99.49 a barrel. Wholesale New York Harbor gasoline advanced 0.2% to $2.916 a gallon. Gold slipped $1.20, or 0.1%, to $1,308 a troy ounce.
