Shares of Walmart (WMT) move higher Tuesday morning after the big-box retailer posted fourth-quarter earnings results, showing quarterly revenue gains of 6% compared to the previous year. This figure was further supported by a 23% gain in e-commerce sales. Additionally, the company announced it has entered a deal to acquire Vizio (VZIO) for $2.5 billion. TD Cowen Senior Research Analyst Oliver Chen joins Yahoo Finance to discuss Walmart's earnings, the potential Vizio deal, and how it can impact Walmart's business going forward. Explaining why Walmart's deal with Vizio can be big for the company, Chen says: "There is a marketplace opportunity in terms of third-party selling [and] there's also a big digital advertising opportunity. And Vizio Connect will help enable this given that they have an operating system that already has about 18 million members, of a Smartcast system, and this will help accelerate digital advertising, which is a very, very high-margin business. 70%-plus margins, as we model it, and it's growing at 30%. So digital advertising is the future of Walmart and we see this as a tech company, as well. That's why it is one of our big ideas."
