Retail stores in Brazil have not been doing very well in a while (take a look at AMAR3, AMER3, CRFB3, LREN3, PCAR3, VIIA3), so I’d advise against buying MGLU3 for now. PRIO3 is a better prospect because the company has a history of good management and the oil industry is resilient in Brazil. Also, right now their stock price seems to be completing a price correction from 42 to 30 (BRL), so now might be a good time to buy shares. I don’t have much to say about UNIP6, though. By the way, since the Grana Capital article was published (01/13/21), MGLU3 went down 85,7%, PRIO3 went up 103,5% and UNIP6 went up 100,8%.
