Loop Capital analyst Anthony Chukumba raised his price target on National Vision (EYE) to $41 and kept his Buy rating, saying the company's amended Management & Services Agreement with Walmart (WMT) extending their cooperation by 3.5 years and adding 5 new locations "de-risks" its investment story. The analyst adds that while the stock trades at a premium to high-growth value retailers on expected earnings basis, its enterprise value to expected EBITDA - which he believes is the more appropriate model based on the company's leverage - is at a discount to the company's peer group.
