About Costco Wholesale Corporation
Costco sells merchandise through membership warehouses and earns revenue from product sales, while membership fees are an additional source of income. Its customers are members shopping for a broad range of goods, and its membership strength is cited as a competitive advantage. The supplied evidence does not provide a breakdown of revenue or profit by business segment, so the relative contribution of merchandise and membership fees cannot be quantified here. Costco reports FY2026 revenue of $303.2 billion and net income of $9.2 billion, compared with revenue of $275.2 billion and net income of $8.1 billion in FY2025.
Notable Price Movement
- Oct 26-30$1,012.280.89%
Costco fell 2.17% over the week, from $1,018.21 to $996.08. Shares declined on three of the four sessions from Oct. 26 through Oct. 29: they slipped to $992.13 Tuesday and $982.73 Wednesday before rebounding 1.36% Thursday. The supplied evidence does not identify a company-specific announcement that explains the weekly decline. A Zacks item says Costco rose while the broader market fell on the latest trading day, consistent with Thursday’s rebound, but it does not establish a catalyst for the week’s earlier losses. Coverage also noted the upcoming $1.47 quarterly dividend, with shares due to trade ex-dividend Oct. 30; the evidence does not connect that event to the week’s price movement.
- Oct 19-23$1,003.321.44%
Costco rose 3.76%, from $959.44 on October 12 to $995.53 on October 19. It dipped to $954.63 on October 13, then rebounded sharply to $982.00 on October 14 on the week’s heaviest reported volume, eased to $978.01 the next day, and advanced again through October 19. No Costco-specific announcement in the supplied evidence explains the rise or the midweek reversal. The broader backdrop included reports of technology-stock weakness tied to AI-spending concerns and rising oil prices, alongside market jitters; those reports provide context but do not establish a direct driver of Costco’s trading. The shares ended the period above their starting level despite that unsettled market backdrop.
- Oct 12-16$989.114.46%
Costco rose 3.89%, from $923.52 to $959.44, advancing through Thursday, slipping slightly on Friday, then adding $12.52 on Monday, October 12. The supplied coverage points to analyst sentiment as a possible support: MarketBeat reported a 1.1% rise after an analyst upgrade, but its snippet does not identify the firm or date, so it cannot explain the full weekly move. MarketBeat also described technical signals as aligning with a potential breakout. No company-specific operating announcement is provided to account for the gains. The broader backdrop was mixed: the Wall Street Journal reported U.S. stocks were mixed as investors pared rate-hike bets, while Allianz’s Mohamed El-Erian argued markets were pricing in too many hikes.
- Oct 5-9$946.922.85%
Costco shares rose 1.20%, from $924.59 to $935.68, over the reported period. They fell to $910.34 on September 30, then recovered over the next four sessions, gaining on October 1, October 2, October 5 and October 6 to finish at the period high. The supplied coverage identifies no company-specific announcement that explains the move. Instead, the relevant market backdrop includes reports that higher interest rates are weighing on consumer stocks and that oil prices have climbed amid renewed geopolitical tension; the evidence does not establish these headlines as direct causes of Costco’s trading. Overall, the stock’s modest net advance followed a sharp early-week pullback and subsequent steady rebound.
- Sep 28 - Oct 2$920.650.23%
COST gained 2.06% over the reported window, from $896.48 on September 24 to $914.94 on October 1, but it finished 0.86% below its September 28 close. Most of the net gain came with the 2.9% rise on September 25, following strong fourth-quarter results: comparable sales grew 9.4%, U.S. comps rose 10.7%, and traffic, ticket size and digital sales advanced. The stock held near $923–$925 on September 28–29, then fell 1.5% on September 30 and recovered only part of that decline on October 1. Analyst target reductions after the earnings beat, including Deutsche Bank’s September 28 cut, and concerns about valuation and margins accompanied the pullback; HSBC’s upgrade and DA Davidson’s target increase were counterpoints.
- Sep 21-25$922.773.07%
Costco rose 1.23% to $904.70, advancing on each of the three reported sessions from September 21 through September 23. The supplied evidence does not tie a specific headline to an individual session, but the stock traded against a mixed Q4 earnings backdrop: Costco beat earnings estimates, while comparable-sales growth lagged and analysts flagged membership growth concerns. Expansion plans and digital growth offered a positive counterpoint. Cost pressure also surfaced in a report that memory inflation triggered a $152 million charge in electronics. Analyst commentary was similarly divided: DA Davidson raised its target, while JPMorgan, Freedom Broker and Bernstein lowered theirs. The steady gain came without a material reversal in the closes provided.
- Sep 14-18$895.311.05%
Costco rose 0.35%, from $915.74 to $918.91 over the stated week. The move was dominated by a sharp rebound on September 14, when shares gained $14.14 from the prior close of $904.77 after falling from $915.74 on September 4 to $902.38 on September 10. No company-specific operating announcement in the supplied evidence explains the rebound. Broader market conditions were mixed: reports described stocks and bonds dipping as central banks raised rates, followed by a U.S. rally as oil prices and Treasury yields eased. Bank of America and JPMorgan subsequently lowered Costco targets, but the supplied closing data do not show a material reversal after those revisions.
- Sep 7-11$904.771.20%
Costco shares fell $33.71, or 3.57%, over the week, from $943.89 to $910.18. The decline was steady rather than reversal-driven: the stock slipped on each reported session, including losses of $3.93 on September 1, $11.48 on September 2, $3.07 on September 3, $9.67 on September 4 and $5.56 on September 8. The supplied evidence identifies no Costco earnings release, guidance change or other company-specific catalyst tied to those sessions. The broader backdrop was dominated by inflation data and expectations for a Federal Reserve rate hike, with financial coverage describing rate-sensitive market volatility despite some index gains. Costco-specific articles discussed Scottsdale approval, analyst views and valuation, but provide no dated trading catalyst.
- Aug 31 - Sep 4$915.743.14%
Costco shares fell 0.99%, from $934.66 on August 27 to $925.41 on September 3. The stock initially rose 1.16% to $945.47 on August 28, then reversed lower, declining in each session from August 31 through September 3 and giving back all of the prior gain. The main identifiable driver was macroeconomic: a surprisingly strong U.S. jobs report lifted Treasury yields and increased expectations for an interest-rate hike, pressuring major U.S. stock indexes and rate-sensitive valuations. No Costco-specific earnings release, guidance change, contract, or management announcement appears in the supplied evidence, so the late-week decline is best explained by broader market repricing rather than new company information.
- Aug 24-28$945.470.24%
Costco shares gained $1.15, or 0.12%, over the week, rising from $933.51 to $934.66. The stock entered the period with a sharp advance, closing at $971.40 on Monday, but then reversed lower for three consecutive sessions and gave back nearly all of that gain. Tuesday’s close fell to $960.01, Wednesday’s to $956.12, and Thursday’s to $934.66, a 2.24% drop that Zacks noted occurred despite broader market gains. The supplied evidence identifies no company-specific earnings release, guidance change, contract, or executive announcement to explain the reversal. Trading therefore appears to have reflected profit-taking or market positioning rather than a documented Costco catalyst, with Thursday’s heavier volume accompanying the decline.
- Aug 17-21$947.741.39%
Costco fell 2.95% over the cited week, from $961.85 to $933.51. The decline was concentrated on Thursday, when shares dropped 2.45% to $933.51 on volume of 2.50 million, after modest weakness on Monday and Wednesday. The stock briefly reversed higher on Tuesday, gaining 0.82% to $961.35, but that rebound did not hold. Zacks reported that Costco underperformed the broader market in the latest session, although the supplied evidence identifies no company-specific announcement, earnings release, or guidance change explaining the move. The most supportable explanation is relative weakness during a broader market decline, with Thursday’s heavier volume marking the week’s decisive selling pressure.
- Aug 10-14$961.101.40%
Costco shares fell 0.14% over the week, from $954.08 to $952.75. The stock declined for two sessions, reaching $941.99 on Wednesday, before recovering to $949.15 on Thursday and ending Friday at $947.82; it then rose to $952.75 on Monday. No supplied evidence identifies material Costco-specific operating news, earnings news, or guidance during the period. Trading instead occurred against a mixed macro backdrop: Reuters reported that rate-hike expectations eased and the S&P 500 reached a record close, while MarketWatch highlighted multiyear-high bond yields and the risk that elevated rates could pressure equities. Costco’s modest rebound came despite that rate-sensitive tension, leaving the stock essentially flat after a midweek pullback.
- Aug 3-7$947.820.43%
Costco fell $18.73, or 1.94%, from $966.58 to $947.85 over the reported week. The stock initially advanced 0.77% to $974.03 on July 29, then reversed sharply, dropping to $954.17 on July 30 and slipping again on July 31. It briefly recovered to $954.08 on August 3 before giving back that gain and closing at the period low on August 4, when volume rose to 2.44 million shares. The supplied evidence identifies no Costco-specific earnings release, guidance change, contract, or executive action explaining the decline. Trading therefore appears to have reflected broader market positioning, including a technology- and retail-heavy tape around Amazon's earnings, rather than a disclosed company catalyst.
