Walmart reports Q2 loss, but higher sales; shares rise

Walmart reported much higher second-quarter sales and robust growth in its e-commerce businesses today, even as it reported a loss on one-time costs associated with selling a Walmart Brazil stake.

The world's biggest retailer scored its most robust jump in more than 10 years in US comparable store sales, sending shares sharply higher. But it reported an $861 million loss following pre-tax costs of $4.8 billion on the Brazil sales.
