Why 2017 Was a Year to Remember for The Home Depot, Inc.

Home Depot Inc (NYSE: HD) once again showed why it is one of the best retailers on the planet as shares trounced the market last year, gaining 41% in 2017, more than double the S&P 500's returns. Of course, the gap between Home Depot's and the index's returns only widens as the comparison period lengthens; the home improvement retailer has a long history of out-performing the market.

Home Depot's latest quarter acts as a microcosm of the store's success. During the quarter, revenue rose to $25.03 billion, an 8.1% increase year over year, and diluted earnings per share grew to $1.84, up 15% from the previous year's quarter. The growth was driven by a 2.5% increase in customer transactions to almost 390 million and a 5.1% increase in average ticket price to $62.84.

Several dynamics go into Home Depot's outsized gains, but you would be hard-pressed to come up with three more important than the company's success with Pro customers, its integrated omnichannel retail experience dubbed "One Home Depot," and the exclusive and innovative products line it offers that keep customers coming back. Let's take a closer look at all three of these factors to better understand Home Depot's continued success.

Getting with the Pro-gram

While Home Depot will never ignore the DIY weekend warrior, it is clear that the future of the company is tied to its success with what it calls its Pro customers. In the company's annual 10-K filing with the Securities and Exchange Commission, Home Depot defines Pros as those who "are primarily professional renovators/remodelers, general contractors, handymen, property managers, building service contractors and specialty tradesmen, such as installers."

At the Oppenheimer Consumer Conference last summer, management stated this market represented about 40% of all sales. But sales to the Pro demographic are far outgrowing sales to DIY customers. In 2017's first quarter, management said Pro sales were growing twice as fast as DIY sales, and in the second quarter, this gap increased. In the third quarter, management only noted that Pro sales were again "outpacing" sales to other customers. This is important because, as a customer segment whose livelihood depends on the supplies Home Depot sells, Pros make more frequent and larger purchases than the average DIY customer.
