The U.S. stock market posted solid third-quarter gains as upbeat news on the global economy overshadowed a steady stream of negative news ranging from catastrophic hurricanes to cyber hacks and war chatter between the Trump administration and North Korea. The S&P 500 Index rose 4% since June 30, notching its eighth consecutive quarterly advance. The Dow Jones Industrial Average added 4.9% in the past three months, posting its longest streak of quarterly advances (also eight) since 1997. This blue-chip index is up 13% this year. Stock market gains also continued to be broad internationally, spanning many regions and sectors.
