Key takeaways

  • Costco publishes net sales and comparable sales every month, while most retailers report only quarterly.
  • Membership fees make up a large share of Costco's profit, so renewal rates and member counts matter to investors.
  • Gasoline sales tie part of Costco's revenue to fuel prices, rising when pump prices climb and falling when they drop.
  • Costco often trades at a higher price-to-earnings ratio than Walmart and BJ's, so small misses can cause outsized drops.

How to read the COST quote

  • Price and daily change: the latest price and its percentage move against the previous close. The timestamp and source show when the figure was captured, which may be after the market closed.
  • Previous close: the final regular-session price of the prior trading day. The daily change is measured from this number.
  • Day range: the lowest and highest trades of the current session. A close near the top of the range means buyers held control into the end of the day.
  • 52-week range: the low and high of the past year. Comparing the current price to the 52-week high shows how far the stock sits from its recent peak.
  • Volume: the number of shares traded in the session. Volume well above normal often comes with news such as a sales or earnings release.
  • Exchange (NMS): the Nasdaq listing code under which the stock trades.
  • Period returns (1D to 1Y, YTD): price changes over each window. They do not show a return on investment that includes dividends or trading costs.

What Costco is

Costco runs membership warehouse clubs. Shoppers pay an annual fee to buy bulk goods at low markups. Membership fees make up a large share of profit, so renewal rates and member counts matter to investors alongside sales. Many locations also sell gasoline. That ties part of revenue to fuel prices, which can raise sales when pump prices climb and lower them when prices fall. Its closest listed competitors are Walmart, which owns Sam’s Club, and BJ’s Wholesale.

What moves Costco stock

Monthly sales reports. Costco publishes net sales and comparable sales every month, unlike most retailers, which report quarterly. Each release gives the market a fresh check on growth. A slowdown from the prior month can push the stock down even when growth is still strong for a retailer of Costco’s size.

Quarterly earnings. Profit, margins, membership fee income and the quarterly dividend come with earnings. The stock can fall after a better-than-expected report if investors had already priced in more.

Fuel prices and the consumer. High gas prices tend to push shoppers toward value retailers and lift Costco’s gas station sales. When oil falls, that support fades. Inflation trends shape the same trade-off between value and spending; see US inflation by year for context.

Valuation. Costco has often traded at a higher price-to-earnings ratio than Walmart, BJ’s and most other retailers. A high multiple leaves little room for error. Small misses against expectations can cause outsized drops, and the stock can lag when investors rotate into faster-growing sectors.

Broad market moves. As a large consumer staples company, COST also moves with the S&P 500 and with shifts between defensive and growth stocks.

Why Costco stock can drop on good results

When shares fall, the cause is usually expectations rather than weak numbers. Growth that slows, even slightly, can lead investors to cut the premium they pay for the stock. Comparing a report against the previous month’s growth and against the stock’s run-up into the release explains most of these moves better than the headline figure alone.
