Stock markets rallied Monday as the prospects for Hillary Clinton’s presidential candidacy improved, with traders reacting to the weekend’s news that the FBI hadn’t found anything new in a reopened investigation into the Democrat’s emails and the latest polls indicating her support holding up.

The Dow Jones Industrial Average rose sharply at the start of trading and was up nearly 2 percent by early afternoon, with strength in all categories. The S&P 500 rose more than 40 points, or more than 2 percent.
