format express concept was a big part of one of the pillars of their turnaround strategy from doug mcmillan. it's just not working? >> small format is definitely one of the pillars. e-commerce is another pillar, and, of course, the core super center business is another pillar. i don't know that it's not working. it's want working at that size. it's not working at the 10,000, 15,000 square foot size. i think it's working fine when you get up to 40,000, 45,000 square feet. those are the neighborhood market stores which they're closing some of those stores, but they're still planning to open a large number of neighborhood market stores in 2016. that concept is working. i just really small stores just are not for wal-mart. >> patrick, perhaps the big story here and what's notable about wal-mart is the resilience of this stock and this company at 2016. it's the only dow component that's actually positive for 2016 by about a percent. now, the cavat is it was the worst performing dow component of 2015. how do you read into the recent relative strength that we've been seeing? is it just overdone la
