This summary was created by AI, based on 48 opinions in the last 12 months.

Costco Wholesale Corporation (COST) is widely regarded by experts as one of the best retailers globally, primarily due to its strong business model, consistent growth, and loyal customer base. Many analysts appreciate its recurring membership fees and the impressive ~92% retention rate, alongside its procurement power leading to solid gross margins. However, there is a consensus that the stock is trading at historically high valuation multiples, often cited in the range of 44x to 53x PE, raising concerns about its sustainability amid a potentially slowing growth trajectory. Analysts generally recommend buying on pullbacks, as they expect long-term growth despite current high valuations. The key takeaway is that while Costco is an exceptional company, prospective investors should be cautious of the lofty price and ensure they are buying at opportune levels.

PAST TOP PICK
(A Top Pick Jan 04/23, Up 61%)

Shares ran up too far. Their business plan is simple: likely open 30 stores a year given insane demand. They just opened one in Shenzen, China. Are only 870 Costco stores vs. 10,000 Walmarts, so there's room to grow. PE isn't cheap, but 10 years from now you will be happy owning this.

COMMENT

It is a stable company which makes its money on volume and membership fees. The Kirkland brand itself generates a huge amount of revenue. However its valuation is quite stretched at 45X earnings.

PARTIAL SELL

She trimmed it before it declined last week after earnings. Really likes it, but Costco is expensive now.

PARTIAL BUY

Shares are down 7% after a mixed quarter after a slight miss on the top and a beat on the bottom; some softness in discretionary spending which is a little concerning. The street was expecting better from membership numbers. They have runway ahead and remain the best big-box retailer.

Trevor Rose’s Insights - Trevor’s most-liked answers from 5i Research

EPS of $3.92 beat estimates of $3.62; revenue of $58.44B missed estimates by 1%. Costco's same-store sales growth remains solid as consumers continue to appreciate value. In-store traffic is the main driver, outpacing gains in average transaction size, a trend likely to persist in fiscal 3Q. Strength in food and sundries is a bright spot, though discretionary spending on some big-ticket items is slowly improving. This is helping drive e-commerce revenue gains, which skew to higher-priced items. Improvements to the mobile app and better advertising campaigns are also aiding digital-sales growth. Inflation is moderating in some categories, letting the company lower prices and reinforce its value proposition, helping to drive robust membership-renewal rates. Merchandise gross margin may slightly expand in 3Q on lower supply-chain related costs. The stock dropped on concern on lower margins, and lack of near-term catalysts, but a planned membership price hike (being considered) may change this. But nothing in the release gives us any real concern, though the stock does remain premium priced.

WATCH

Retail advantage: low prices due to its club membership model. They report tomorrow. Also, they have such scale, they can collect massive data and harness that data using AI to better predict their business.

BUY ON WEAKNESS

Excellent business, but valuation of stock price is high. Amazing management of business with own processes that keep prices low for customers. Is excellent for long term holders to buy (5+ years). Membership fee allows company to weather ups and downs of retail. 

COMMENT

New managers in early March will focus on raising digital sales, which are only 7% of overall now. COST is a permanent compounder.

BUY

Loves it. Loves their subscription model. Likes today's price increase by Wall Street. Generates tons of cash and can withstand a consumer slowdown. He own Walmart for similar reasons.

PARTIAL BUY

Sometimes the best time to plant an oak tree is today. If you're trying to find the best time to buy, buy half now, and the rest on a downdraft. Well run, usually delivers. Short-term suggestion that it can come back into its range.

TOP PICK

Costco Wholesale Corporation, together with its subsidiaries, engages in the operation of membership warehouses in the United States, Puerto Rico, Canada, the United Kingdom, Mexico, Japan, Korea, Australia, Spain, France, Iceland, China, and Taiwan. It offers branded and private-label products in a range of merchandise categories. Social media mentions are up 267% in the past 24h.

HOLD

Not a fan of retail, except for this one. The best, well run. 

BUY ON WEAKNESS

Recent pullback good time to buy. Excellent business overall. Highly valued, but a good long term investment. Could be better opportunities in Dollar General for capital appreciation. 

BUY ON WEAKNESS

A leader. Dominant position in US. Buy on any day "that ends in 'y'". Always seems expensive if you look at the high 30s PE ratio. Chart looks stretched. Look for a pullback, perhaps when December seasonality subsides early in the new year. Membership rate increases every couple of years creates earnings power, as there are few good substitutes.

About as good as it gets on long-term buy and hold.
