NEW YORK, Nov 29 (Reuters) - Stock prices around the world rose on Tuesday following upbeat U.S. growth data and strength in U.S. healthcare shares, while oil prices tumbled to the weakest level in over a week on doubts OPEC could reach an accord to reduce output.
The dollar fell against a basket of currencies on profit-taking. The dollar index had hit a near 14-year peak last week on expectations a Trump administration would result in tax cuts and a surge in federal spending to bolster the U.S. economy.
"Optimism surrounding potential fiscal stimulus and some targeted deregulation next year have lifted U.S. equity prices in recent weeks," said Jim Baird, chief investment officer at Plante Moran Financial Advisors.
"Couple that with an increasingly enthusiastic consumer supported by stronger wage gains, and the economy appears well-positioned to remain on a growth path heading into 2017."
Concerns about rising government borrowing to finance fiscal stimuli, together with upbeat U.S. economic data, spurred early selling in U.S. Treasuries and other core government bonds before month-end related buying emerged, pushing their yields lower.
Gold prices fell on growing expectations of stronger global growth led by the United States and the Federal Reserve raising interest rates in response.

UNH.N 3.6 percent rise to a record high after the largest U.S. health insurer's upbeat forecast boosted the healthcare sector. equities ended higher, with Italian bank stocks gaining 4 percent .FTIT8300 after Monte dei Paschi's rescue plan got off to an encouraging start. Italian insurer Generali's board approved a conversion of 400 million euros in Monte's subordinated bonds into shares, according to Italian press reports. BMPS.MI GASI.MI

In addition to its bank sector, Italy was also in focus ahead of a constitutional referendum on Sunday. 10-year government yields IT10YT=RR fell below 2 percent after Reuters reported that the European Central Bank is ready to buy more Italian bonds if there is turmoil after the constitutional referendum on Sunday.
