Things are looking up. U.S. stocks posted gains Monday as investors welcomed a plan announced by France and Germany to resolve the euro zone’s debt crisis by the end of the month. The Dow soared 330 points after closing down Friday, the S&P 500 was up 39 points, and the NASDAQ rose 86 points, as financial and energy stocks saw promising gains. The rally in U.S. markets was prompted by similar gains in Europe after the euro posted its biggest gain in 15 months against the dollar.
