Through all the ups and downs in the market this year, one thing has been pretty consistent: Walmart (WMT) - Get Report .

Shares of the world's largest retailer are up a cool 17% year to date, trouncing the Dow Jones Industrial Average's 8% gain. Walmart isn't exactly a startup seeing exploding sales and profits because it has solved world hunger or some other daily nuisance. No, it's the world's largest retailer with over 4,700 stores in the U.S. and steady quarterly same-store sales and profits.

Understanding why Walmart shareholders are enjoying such a good year isn't as easy as studying the financials. In many respects, the financials are only one component to the larger story of perception. That was something reinforced to me and the consumer team here at TheStreet on Wednesday as two key Walmart contacts came for a visit. Although what was discussed can't be revealed, the key takeaway is that Walmart is not the same company it was five years ago (or even a year ago). It's hungry, determined and moving at a speed that should frighten a grocery store like Kroger (KR) - Get Report and fellow discounter Target (TGT) - Get Report

Welcome to the new age of Walmart. 

Walmart shares were up 0.5% to $79.92 at Wednesday's close.
