Why It’s Moving

Costco’s strong sales are colliding with a valuation reset ahead of earnings.
- Costco reported August net sales of $23.7 billion, up 9.9% year over year, while comparable sales increased 8.4% and digitally enabled sales climbed 17.9%—evidence that customer demand remains resilient even at the company’s large scale.
- Freedom Broker upgraded Costco to Buy from Hold on September 8, citing the strong sales momentum and supporting a more constructive view of the retailer’s growth profile.
- Shares have remained under pressure despite the sales strength, highlighting investor sensitivity to Costco’s rich valuation and setting up the September 24 fiscal fourth-quarter report as the next major test.

Lowe’s moves lower as investors weigh solid earnings against a softer 2026 outlook.
- Lowe’s shares have been under pressure after the stock slipped to a fresh 52-week low, signaling investors are focusing more on slowing demand than on the recent earnings beat.
- The latest quarterly results showed adjusted EPS topping estimates, but revenue came in slightly light and management trimmed full-year sales expectations, reinforcing worries that DIY spending remains soft.
- Analyst updates have stayed broadly constructive, yet several firms cut price targets in response to the softer outlook, keeping attention on how quickly home-improvement demand can stabilize.
