The boost sent shares to new highs, with the stock having gained over 300% since early 2015.

So what

January's rally came as investors grew more confident that Wayfair enjoyed solid sales growth over the critical holiday shopping season. We know, for example, that revenue spiked by 53% during the five-day weekend period following Thanksgiving. That demand bounce was powered by thousands of orders for bulky merchandise, Wayfair said, including pool tables, hot tubs, and even a single 3,900-pound delivery of a storage shed.

Rival Amazon.com reported booming sales for the quarter, too. It sold 35% more products this past holiday season, despite its already massive revenue base.

Now what

It's good news for the business that customers are getting comfortable with shopping for their home furnishings, including things like sofas and dining tables, online. But investors will find out whether Wayfair was able to deliver these products efficiently, and at a profit, when it announces its full fourth-quarter results on Thursday, Feb. 22.
