Here's a look at global markets. US stock markets snapped a six-session rebound Tuesday, with retailers falling especially hard following disappointing results from Walmart. The world's biggest retailer plunged 10.2 percent after reporting a 42 percent drop in fourth-quarter earnings. That revealed growing pains in the company's e-commerce buildout.

The Dow Jones Industrial Average finished down 1 percent. The broad-based S&P 500 fell 0.6%. And the NASDAQ slipped 0.1 percent. US yields rose in government debt auctions, bolstering the US dollar. Key eurozone stock markets posted gains as a weaker euro gave exporters a boost. Bourses in Frankfurt and Paris climbed higher. London finished down slightly following disappointing results for HSBC and BHP.
