"EBay doubled their quarterly rate of share buybacks in Q4, and 2017 revenue guidance implies a re-acceleration of marketplace growth, which indicates the company is confident their structured data initiative can help stem the rate of market share losses," said Wedbush Securities analyst Aaron Turner. EBay, which spun off its main growth engine PayPal Holdings Inc in 2015, has revamped its platform to offer a bigger selection of products and brands. The company now also requires sellers to give more details on items to attract younger shoppers and has been cutting listing costs. Although turning around, the marketplace is "still a laggard", added Mr Gillis, noting that 4 per cent revenue growth for eBay's marketplace, accounting for foreign exchange rate changes, paled in comparison to e-commerce growth at an estimated 15 per cent.
