Costco (COST)

Costco's price just crossed $1,000 for the first time, sitting about 4% above its longer-term trend.

What is going on right now?

The stock has climbed unusually fast lately, with more shares changing hands than usual. Streaks like this have often taken a breather.

How is the business itself doing?

Costco's sales grew about 11% and its profits grew around 15% last quarter. It keeps very thin margins, roughly 3 cents of profit on every dollar, so even small changes in what it pays for food or fuel show up quickly.

What stands out?

A food supply disruption reported on October 19 may push up the cost of goods Costco brings in. With margins that thin, that matters more here than at most other companies.

What comes next?

Costco's next earnings report lands on December 10, the first to reflect recent spikes in oil and food costs.
