What happened Shares of Jumia Technologies (NYSE: JMIA) soared 42.6% in January, according to data provided by S&P Global Market Intelligence. The stock was one of the top performers in 2020, up 500% last year alone. And investors remained enthusiastic in January, possibly because of positive news regarding the company's food-delivery business. So what To be clear, news for Jumia was scarce in January, despite its market-crushing performance. But according to an article from Nigeria Communications Week, the company expanded its food-delivery service in Nigeria last month. It may have just been a coincidence, but the stock surged in the days following this development. Image source: Getty Images. Greater availability of food delivery fits the narrative Jumia's management laid out at the Needham Virtual Growth Conference in mid-January. According to management, the average value of Jumia users' orders shrinks over time. The trend suggests users start thinking about e-commerce for more mundane regular purchases rather than solely for one-time special purchases. That's an important shift as Africa dives deeper into e-commerce, and food delivery certainly plays a role in that. Now what To be sure, Jumia made some game-changing moves in 2020 that I believe make it a better company. But for this to be a long-term winner, the company will have to start backing up hopes with business results.
