Global stocks are mixed after Wall Street's best week of the year; yen rallies

World stocks are mixed as investors ponder the upcoming meeting of the Federal Reserve, following Wall Street's best week since November. U.S. futures were higher while oil prices dropped. The yen was 1% higher against the dollar as rising bets on a Fed September rate cut dragged the dollar down. The market’s focus this week will be at Jackson Hole, Wyoming, where Federal Reserve Chair Jerome Powell will give a speech at a setting where big policy announcements have been made in the past. The S&P 500 rose 0.2% on Friday, extending its winning streak to a seventh day. The Dow Jones Industrial Average rose 0.2%, and the Nasdaq composite gained 0.2%.
