Sr. EVP Russell D Miller sold 1,500 COST shares at $916.32; stock now at $943.08, -12.4% from 52-week high.
Russell D Miller, Sr. Executive Vice President of Costco, sold 1,500 shares on 2026-01-09 at $916.32, reducing his holdings to 8,240 shares (8.2K shares) from 9,740 shares (9.7K shares). The sale occurred when the stock was trading 12.4% below its 52-week high of $1,076.86, and the current price of $943.08 stands just 2.9% above the transaction price. At Costco specifically, Miller's prior three trades show mixed timing outcomes: his 2023-11-03 and 2024-10-11 sells preceded positive 90-day returns (+26.3% and +4.1% respectively), while his 2025-09-29 sale preceded a 90-day decline of -4.6%, resulting in a 1-of-3 well-timed rate at this ticker. Costco's valuation remains elevated at a P/E of 50.43 despite solid fundamentals (annual revenue growth +8.2%, Q latest revenue $17.8B, market cap $418.6B), and the 30-day post-transaction return of +6.6% suggests modest near-term momentum unrelated to the sale.
