Vincent Shen: Let's paint a little bit of a picture here. I think some people are familiar with the fact, once you reach the scale, similar to McDonald's, that Wal-Mart has reached, doing anything that really moves the needle for the company becomes really challenging. But, before McMillon took the helm and became, potentially, the most qualified CEO since Sam Walton, what was Wal-Mart facing? And then, we can get into the steps that he took.

Sarah Priestley: I would say Wal-Mart essentially came to prominence by saturating markets. They were the most convenient option at the lowest price. But the problem is, now, they have competition from all sides. From the lower end, Dollar General and the dollar stores' increasing popularity. Costco and Target as the big-box retailers. Kroger, they've really upped their game in terms of organic and fresh. I think Wal-Mart missed the mark on that, initially. If you look, a decade ago, Wal-Mart was 15% to 18% cheaper on groceries than Kroger. The gap is now 4% to 7%. So that's getting a lot shorter. And, the other thing is, in terms of convenience, Walgreens and CVS are leveraging their geographic dominance and offering groceries there, so people have another alternative. 

More than all of that, though, is online. If you look, Amazon, 2012 to 2015 doubled their sales. Wal-Mart grew their sales by 8.6% in the same period. It's the Amazon effect. There's definitely online sales, which is taking away from Wal-Mart revenue.

Shen: Yeah, with that kind of growth ... unfortunately, consumer spending has not been growing at that rate. That is Amazon taking share, especially, from a lot of the traditional retailers, Wal-Mart being, in my opinion, the epitome of that.
