As part of the annual Russell index reconstitution, FTSE Russell added Costco (COST) to the Russell 1000 Value Benchmark and removed Applied Materials (AMAT), according to reports. The changes reflect a reclassification of companies based on market capitalization and style criteria (value vs. growth).

Costco’s inclusion follows its market cap surpassing $400 billion, making it a strong candidate for value indexes. In contrast, Applied Materials was removed as its stock style shifted toward growth. Per market data, COST closed at $952.54 on June 26, 2026, while AMAT closed at $626.84 on the same day.

Investors are watching the impact on passive fund flows tracking the index. COST may find support near $943 (the session low) and resistance at $961.64. AMAT could test support at $622. No major company-specific catalysts are scheduled in the coming week, but focus will remain on portfolio rebalancing.
