Reuters/StringerHere is what you need to know. Stocks usually go up after a solar eclipse. Stocks have returned an average of 17.2% in the 12 months following a solar eclipse, according to data compiled by LPL Financial. Goldman Sachs says this may not be the big correction we've been waiting for. Technical strategist Sheba Jafari says stocks are in the fourth wave of a five-wave cycle and "in theory have at least one more advance." German economic sentiment drops sharply.
