UBS analyst Michael Lasser raised his price target on Costco (COST) to $280 and kept his Buy rating as part of his deep dive analysis into warehouse clubs. The analyst says the model "remains relevant" and has a "sturdy place" in the omnichannel world, noting that his survey of 1.5K shoppers shows that consumers are loyal to the concept. Lasser cites 91% of Costco members responding that they are "very or somewhat likely to renew", which outpaces intentions recorded at Sam's Club (WMT) and BJ's (BJ). The analyst further notes that Costco has produced 8 consecutive quarters of mid-single-digit core comp growth, suggesting the company's "leadership in this category".
