Walmart earnings are the talk of the town today, as per usual when the world’s largest retailer reports. The first quarter is especially important as it includes buying before key holidays such as Mother's Day, Easter, and Memorial Day.

Sozzi shares three key developments at the company that nobody is talking about, including store closures in China, new energy-efficient lighting coming to Walmart's UK Asda stores, and new store openings announced in the last two months.
