[NEW YORK] The Dow and S&P 500 closed at record highs on Tuesday, lifted by further gains in healthcare shares and hopes for a stronger global economy.
The S&P 500 scored its fourth straight day of gains.
Actavis Plc, Gilead Sciences and other biotechs were among the biggest drivers, a day after Allergan agreed to be bought by Actavis. The Nasdaq biotech index rose 2.1 per cent.
The S&P health care index added 1.6 per cent. Shares of Actavis were up 8.7 per cent at US$269.60, helped by bullish analyst notes, while Gilead's stock rose 3.3 per cent to US$103.71 per cent. "A little bit of a risk trade is coming back on, and those are the areas for the M&A," said Uri Landesman, president of Platinum Partners in New York. "It's a very, very good environment to buy growth, so I don't quibble with the notion that there's going to be more M&A." Among the biggest boosts to the Dow, shares of UnitedHealth were up 1.8 per cent at US$98.19.
Further supporting stocks, news of a snap election and a delayed tax increase in Japan strengthened hopes for new stimulus, a day after data showed Japan back in recession. In Europe, German analyst and investor sentiment advanced this month for the first time in almost a year.
Benign U.S. inflation data also helped.
The Dow Jones industrial average rose 40.07 points, or 0.23 per cent, to 17,687.82, a record high. The S&P 500 gained 10.48 points, or 0.51 per cent, to 2,051.8, its biggest one-day move since Nov 5.
The Nasdaq Composite added 31.44 points, or 0.67 per cent, to 4,702.44.
Actavis was the S&P's biggest percentage gainer; the largest decliner was Urban Outfitters, down 6.6 per cent at US$28.79, following results.

About 6.1 billion shares traded on US exchanges, below the 6.4 billion average this month, according to BATS Global Markets.
