Here’s an article by Timo Heikkilä about Walmart that only takes a few minutes to read 
Walmart* is undergoing a transformation: the company is shifting from a traditional grocery giant towards a secularly growing, technology-driven retail company, with e-commerce, advertising business, data, logistics, and membership models at its core. This makes Walmart a very suitable target for a quality-focused portfolio. Walmart is indeed the largest investment in our II-Quality portfolio.
Walmart’s* valuation multiples are high, but strong quality, steady cash flow, and a structural competitive advantage support the premium. The technical picture also supports the investment case: momentum is clearly positive and the trend is upward. For investors, Walmart offers defensive quality combined with a reasonable growth profile.
