Costco Wholesale shares are looking very attractive to investors as retail spending remains tight, and that sentiment is probably going to intensify as spending becomes even more volatile heading into election season, UBS analysts say in a research note. “As this takes place, Costco’s share gains will look even more compelling and the stock will sustain its premium valuation,” the analysts say. The market currently has little appetite for market share losers, and Costco is positioned to keep scooping up market share as macroeconomic strains have more consumers seeking out warehouse memberships to maximize their spending power, the analysts say.
