I first pointed to what I called “retail’s great bifurcation” literally two years ago today. Though it wasn’t the first time that I had observed what I saw as the impending collapse of the middle. I began writing and speaking about that during 2011. As we emerged from the financial crisis it seemed clear to me that retail brands were faced with the proverbial fork in the road. A strategy of being just about everything to everybody–of selling average products to average people in an average experience–was becoming increasingly untenable. While it’s easy to credit the “Amazon effect,” or the overall rise of e-commerce, that’s only part of the story. The fact is many factors conspired to squeeze the middle, while, for the most part, the two ends of the spectrum continue to thrive. For years now brands that execute well on price, dominant assortments, buying efficiency and convenience are winning. Amazon, Walmart, Best Buy, Home Depot, Costco and virtually all the off-price giants and dollar stores, are driving strong growth and profits. And–I hope you are sitting down for this–despite the silly retail apocalypse narrative, they are all opening stores–in some cases lots of them. Similarly, we find many success stories at the other end of the spectrum. Most established luxury brands are experiencing strong growth, as are higher-end specialty retailers who have a tight customer focus, offer a superior experience and provide a real emotional brand connection. Think Apple, Bonobos, Nordstrom, Sephora, Ulta, Warby Parker and many more. Somehow living in the age of Amazon and digital disruption has not come remotely close to creating an existential crisis for these retailers. Read more at Forbes.
