Why It’s Moving

Costco’s latest sales update is keeping analyst sentiment constructive, even as valuation remains a sticking point
- Analysts turned more positive after Costco’s latest sales update, suggesting the company is still converting membership loyalty and traffic into steady top-line growth despite a premium valuation.
- A fresh upgrade from Freedom Broker and a reiterated Buy from BTIG kept sentiment constructive, reinforcing the view that Costco’s defensive model and consistent execution remain a draw for investors.
- Some firms stayed cautious, pointing to valuation concerns and mixed read-throughs from August sales, which is tempering enthusiasm even as the broader analyst consensus stays upbeat.

Nike slides as index removal and fresh lows keep turnaround fears in focus
- Nike was removed from the S&P 100 after nearly 18 years, a sign that the market is no longer treating the company as a top-tier blue chip and is focusing instead on its prolonged slowdown.
- Shares hit a fresh 52-week low this week, underscoring how weak demand, discounting pressure, and turnaround skepticism are still weighing on sentiment.
- Recent analyst commentary stayed cautious, with firms pointing to softer China demand, competitive pressure, and profit headwinds from Nike’s turnaround spending.
