William Blair reiterates Outperform rating on Costco stock amid strong October comps

Investing.com - William Blair has reiterated an Outperform rating on Costco Wholesale (NASDAQ:COST) following the company’s strong comparable sales performance in October. This aligns with the company’s impressive track record, as InvestingPro data shows Costco has delivered a strong 5-year return and maintains a solid market cap of $414.39 billion. However, with a P/E ratio of 51.53, the stock appears to be trading above its Fair Value according to InvestingPro analysis.

The research firm highlighted Costco’s merchandising strategy as a key competitive advantage, noting the retailer has successfully reduced seasonal merchandise like toys and holiday decor with Chinese sourcing exposure while shifting toward apparel and home goods that maintain relevance beyond the holiday season. As a prominent player in the Consumer Staples Distribution & Retail industry, Costco has managed this strategy despite relatively weak gross profit margins of 12.84%.

Store visits by William Blair revealed noticeably limited Halloween and Christmas inventory compared to previous years, yet October’s healthy comparable sales indicate Costco has maintained customer conversion with its new category focus.

William Blair views Costco’s strong October performance, along with slight improvements in broader retail trends over the past two weeks, as a positive indicator for better-than-expected holiday sales, despite increasingly bearish market expectations that emerged in early September.

The firm believes Costco is well-positioned as a market share winner in the current retail environment due to its curated product mix, value proposition, and higher-income customer base, though it notes the broader retail landscape will likely remain bifurcated with continued weakness among lower-income consumers.

In other recent news, Costco Wholesale has been the subject of multiple analyst updates. UBS reiterated its Buy rating with a price target of $1,205, noting the company’s strong performance despite a slowdown in September sales. BTIG initiated coverage on Costco with a Buy rating and a $1,115 price target, emphasizing customer loyalty as a key driver for continued growth. Bernstein maintained an Outperform rating, adjusting its price target to $1,134, and highlighted the company’s valuation pullback from a mid-50s to a mid-40s price-to-earnings ratio. Oppenheimer also lowered its price target to $1,050 but kept Costco as a top pick, despite the stock’s recent underperformance compared to the S&P 500. Bernstein further reiterated an Outperform rating with a $1,140 target, mentioning challenging year-over-year comparisons, particularly in categories like gift cards and gold sales. These developments reflect varying analyst perspectives on Costco’s valuation and growth prospects.
