So what

Stitch Fix reported solid earnings results in early June that suggested continued market share gains for its disruptive approach to selling clothing online. Sales rose 17% thanks to healthy growth in key engagement metrics including the active customer base, average spending per order, and client satisfaction.

Now what

CEO Katrina Lake and her team have outlined an ambitious year ahead as Stitch Fix moves deeper into product categories like men's clothing and kids' wear. It has also begun its biggest international expansion yet with a push into the U.K.

Sure, the stock appears expensive given its paltry earnings profile. But Stitch Fix is paving the way toward robust profitability in future years by rapidly building scale and working to educate consumers about the benefits of its push-based selling model. If it keeps winning on these points, expect more market-thumping returns ahead.
