Stocks edge up on U.S. data, healthcare sector; oil flops

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.
