Retailers are staying busy even after Christmas

The end of December is being referred to as "the 13th Month" by retailers, as it's generating a huge amount of traffic among shoppers, according to the New York Times. Per the NYT, 40% of people planned to shop after Christmas, compared to only 5% five years ago.

Why it matters: Consumer confidence is at an almost 17-year high, per the Times, which is pulling more and more people online and into stores. Retailers have been concerned about losing business to Amazon, but this year's "vibrant holiday season" is easing those concerns.
