Stock market wavers as Europe's economy slows

Constellation Brands soared 37 percent, the biggest gain in the S&P 500, after reaching a deal with Anheuser-Busch InBev. InBev agreed to sell a brewery in Mexico and rights for Corona and Modelo beer in the U.S. to Constellation for $2.9 billion. Constellation Brands gained $11.87 to $43.75.

In the market for U.S. government bonds, the yield on the 10-year Treasury slipped to 1.99 percent, down from 2.02 percent the day before.

The 10-year Treasury yield, used to set a variety of borrowing rates, began the year around 1.70 percent and has climbed steadily higher since then. As worries about a recession ease, traders have shifted money out of the Treasury market, driving yields up.

Among other companies making news:

— Whole Foods Market slumped 10 percent. The grocery store chain trimmed its forecasts for sales and earnings this year, a result of its plans to open more stores and put more lower-priced goods on its shelves. Whole Foods lost $9.40 to $87.50.

— General Motors fell 3 percent after the biggest U.S. carmaker said it made money in North America and Asia and nearly doubled last year's fourth-quarter profit. But its earnings fell short of analysts' estimates. GM's stock dropped 92 cents to $27.75.
