Markets Close Higher on Better Retail Sales, Citigroup Earnings

Markets closed higher, buoyed by the best growth in US retail sales data in the past 1.5 years and better than expected earnings from Citigroup. Suggestions of more QE in Europe added to the positive tone, though sentiment in U.S. markets was volatile over the session - the Nasdaq ranging between gains of more than 1% and losses. Names such as Google, GE and Coca-Cola are all due to report this week, but traders said sentiment remained fragile. Jane Searle speaks with Greg Keating at the NYSE.
