NEW YORK – U.S. stocks gained slightly Monday as a flurry of deal news involving companies such as American International Group Inc. spurred optimism about the economic outlook, but investors were cautious a day before the Federal Reserve's final meeting of the year.
The Dow Jones industrial average gained 20.99 points, or 0.17 percent, to close at 12,328.48. The Standard & Poor's 500 Index ended up 3.20 points, or 0.23 percent, at 1,413.04. The Nasdaq Composite Indexgained 5.50 points, or 0.23 percent, to finish at 2,442.86.
Shares of blue-chip insurer American International Group Inc. (AIG) helped lead the Dow Jones industrial average's advance with a 0.9 percent gain after state-owned Dubai Ports World said it had agreed to sell its U.S. port operations to an AIG unit. It was the stock's biggest one-day climb in nearly a month.
Speculation that Continental Airlines Inc. (CAL) could become the target of a takeover attempt propelled the carrier's stock up 8.2 percent.
"The bias is still to the upside," said Angel Mata, managing director of listed equity trading at Stifel Nicolaus Capital Markets in Baltimore.
"It's a liquidity issue. You have a lot of money to buy financial assets. In addition, we're dealing with the fourth-quarter and the end of the year, when most money managers are tyring to get stocks to go up — not down."
Wall Street expects the Federal Reserve to leave U.S. interest rates unchanged for the fourth straight time when its policy setters conclude their last meeting of 2006 on Tuesday. But investors are anxious to learn what the Fed will say about economic growth and inflation.
The Fed has held the fed funds rate target steady at 5.25 percent since August, when it paused after raising rates 17 times in a tightening cycle that began in June 2004.
"We've been getting some conflicting numbers about whether or not the economy is growing or slowing. So it will be nice to see what the Fed says," said Joe Saluzzi, co-manager of trading at Themis Trading in Chatham, New Jersey.
"The market wants to see the Fed saying inflation is tame and growth is moderate."
Both the Dow and the S&P 500 got major support from a jump in the shares of the nation's three biggest banks following speculation late last week that Citigroup Inc. may shed one or more units and shake up senior management.

JPMorgan was the Dow's second-biggest advancer. Morgan Stanley raised its rating on the stock to "overweight," according to a report by MarketWatch.
AIG, up 65 cents at $71, ranked third among the Dow's biggest gainers. It also was among the top six stocks contributing the most to the S&P 500's advance.
Bank of America (BAC) topped the S&P 500's list of advancers.
