Huh?

According to this story, retail sales fell in April by 0.4%, while according to this one, they were up by 1.2% in the same month. Both stories are carried by Yahoo Finance (sourced from Bloomberg and NYTimes via Indian Express), and both were posted within minutes of each other, probably by the same journalist -- as indicated by the URL. Mind you, it could be that one of these numbers is year-on-year while the other is month over month, but it's still sloppy journalism if I have to figure this out on my own.
