The Dow Jones Industrial Average rose 65.12 points (0.40 per cent) to 16,514.37, the third day in a row to see a gain.
The S&P 500 added 7.66 (0.41 per cent) at 1,879.55, while the Nasdaq put on 39.91 (0.97 per cent) to 4,161.46.
A series of deals between pharmaceutical giants Novartis, GlaxoSmithKline and Eli Lilly shuffled more than $US20 billion ($A22 billion) in assets.

“The market sentiment seems to have turned much more positive.”
Levy said the tech stocks have re-emerged as leaders after languishing for much of March and early April.
These include Facebook (+2.9 per cent), Tesla Motors (+7.0 per cent) and Gilead Sciences (+1.8 per cent).
