Nvidia’s results stole the show this week. Third-biggest S&P 500 cap, the group’s figures had as much, if not more, impact on markets than a central bank meeting. Before the results came out after Wednesday's close, several mixed economic indicators suggested markets should perhaps mark a pause: PPI inflation was higher than expected and there were conflicting signals on activity like a drop in housing permits. The Philly non-manufacturing survey and the Conference Board’s Leading Index also fell and Michigan University's investor confidence index rose less than expected.
