JUMBO BUYBACK: Boeing gained $1.63, or 1.2 percent, to $136.40 after the plane maker increased its stock buyback program by $10 billion and raised its dividend 52 percent. 3M climbed $2.92, or 2.3 percent, to $130.58 after raising its dividend by 35 percent. The company also forecast solid earnings next year.
THE FED EFFECT: The stock market has surged this year as the Fed keeps buying $85 billion in bonds every month to keep long-term interest rates low. The economy has steadily improved and companies have been making more money. That has helped push the S&P 500 index up almost 25 percent, putting it on track for its best performance in a decade.
ROOM FOR OPTIMISM: The strong economy and healthy earnings provide a good backdrop for stocks, says Liz Ann Sonders, chief investment strategist at Charles Schwab. "Dips that we get are not going to be terribly severe," Sonders says.
NO CORRECTION: The S&P 500 has gone without a correction, defined as a decline of 10 to 20 percent, since October 2011.
BIGGEST WINNERS: Frontier Communications rose the most in the S&P 500. Shares surged 37 cents, or 8.4 percent, to $4.76 after the company reached a deal to acquire AT&T's fixed-line business in Connecticut for about $2 billion.
AND LOSERS: Healthcare stocks fell the most, led by medical technology company CareFusion and hospital operator Tenet Healthcare.
FLAT PRICES: U.S. consumer prices remained flat in November, held down by falling gas prices. The consumer price index fell 0.1 percent in October.
OTHER MARKETS: The yield on the 10-year Treasury note dropped to 2.86 percent from 2.88 percent from Monday. The price of gold fell $14.20, or 1.1 percent, to $1,230 an ounce.
ON DECK: The Fed will also release economic projections and hold a news conference on Wednesday. Several big U.S. companies are due to report quarterly earnings this week, including FedEx, Oracle Corp and Neiman Marcus.
