Rounding out the portfolio…

Costco Wholesale Corp. (COST) has been one of the market’s top performers over the past decade, but don’t let its big run scare you away. BMO Capital Markets food retail analyst Kelly Bania said the stock has more room to grow and confirmed Costco as a top pick in a note out this week. Her refreshed rating is based on three major announcements made recently by the company: a $10 monthly credit on same-day Instacart orders for executive members; extended shopping hours, also for executive members; and a standalone gas station test taking place in California. “These new benefits and perks highlight Costco’s extreme membership value proposition, particularly the key executive membership base, which accounts for 47 per cent of members but 73 per cent of sales,” Bania said. Bania has set a price target of US$1,175, a level the stock topped on Feb. 13 before slumping in March. Year to date, Costco is up 7.5 per cent and closed Friday at US$985.14.

Nike Inc. (NKE) 
The sports-giant is back in the running after its latest earnings appeared to show Nike’s year-long sales slump is coming to an end. Deutsche Bank AG analyst Krisztina Katai lifted her target to US$77 Friday from US$71. Nike jumped 15 per cent on Friday and was trading at US$72.04.

Nvidia Corp. (NVDA) The darling of the Magnificent Seven stocks could elevate itself into further rarified territory as it looks to become the first company to reach a US$4 trillion market capitalization. Nvidia’s prospects were boosted on reports that its largest customers including Meta Platforms Inc., Microsoft Corp., Amazon.com Inc. and Alphabet Inc. are set to increase spending on artificial intelligence. Shares of the company were up nearly 10 per cent from last Friday and are up 67 per cent after slumping badly in early April when it looked like its chip business would be throttled by trade troubles between the U.S. and China. The consensus price target from analysts who cover the company rose to US$173.47 from US$171.38. Nvidia closed Friday at US$157.75.
