(Bloomberg) -- Costco Wholesale Corp. shares pushed past the $1,000 mark for the first time in a year, closing at $1,008.79 on May 8, a psychologically significant level that brings the "Sell in May" adage into sharp focus for the warehouse giant.
"Members are focused on quality, value, and new, exciting items. When we meet these expectations, members seem willing and able to spend," Costco CFO Gary Millerchip said on the second-quarter earnings call, describing a resilient consumer base that continues to power the company's growth.
The stock's 17% year-to-date surge has been built on robust fundamentals, including a 13% year-over-year increase in April net sales to $23.92 billion and a 7.4% rise in second-quarter comparable sales. Membership fee income, a key profit driver, grew 13.6% to $1.355 billion from 82.1 million paid members globally, who renew at a nearly 90% rate.
However, the ascent to a new high-water mark raises valuation questions. The stock now trades at a premium 52 times trailing earnings and 46 times forward estimates, with a price-to-book ratio near 14. This rich valuation comes against a backdrop of weakening consumer sentiment, with the University of Michigan's index falling to a record low of 48.2 in May. Four Costco executive vice presidents sold shares at prices between $991 and $1,003 in March and April.
Analyst Bull Case vs. Valuation Headwinds
Despite the heady valuation, Wall Street analysts see further upside. Deutsche Bank has set a price target of $1,106, Goldman Sachs is at $1,088, and Bank of America is the most bullish with a target of $1,185. The consensus is buoyed by Costco's dominant membership model and consistent sales growth, which are seen as defensive strengths in an uncertain economy.
The case for caution centers on the stock's premium multiple compared to retail peers and historical ranges. The last time Costco stock breached the $1,000 level in May 2025, it failed to hold and drifted lower for the remainder of the year. Investors are now weighing whether the company's strong performance justifies its expensive price tag, especially with prior support levels at the 200-day moving average near $952 and the 52-week low of $844.06 offering potential valuation reference points.
