Wall Street jumped out to a huge gain on Monday, with investors celebrating the fact that election results in France were reasonably close to what most of those following the political situation there had foreseen. Stock futures were up before U.S. markets even opened, and the Dow soared more than 200 points and helped lead major market benchmarks to gains of between 1% and 1.5%. Moreover, positive news from several individual stocks provided even more upward momentum to the market’s move. C.R.
