Delta Descends, Banks Backslide as Earnings Season Leaves Stock Markets Mixed

Wall Street got off to a mixed start on Tuesday, as investors tried to weigh economic data, political maneuverings, and company fundamentals. For Delta Air Lines (NYSE: DAL), the news wasn't as good as many had hoped to see from the airline giant. Meanwhile, big banking institutions are in the spotlight this week, and with both JPMorgan Chase (NYSE: JPM) and Citigroup (NYSE: C) seeing their shares lose ground Tuesday, it's clear that investors didn't get everything they'd hoped for.
