Costco Wholesale Has Fallen More Than 10% From Its Peak Before. Here's What History Says Happens Next.

Costco's stock has declined over 18% from its May 2026 peak. Historically, the stock recovered to new highs within 12 months in 5 of 7 previous 10% declines. However, recent exceptions (2022 and 2025) suggest caution, as recovery took much longer when valuations were steep. Currently trading at a P/E of 47.3 (above the 10-year average of 40), the stock may drift sideways as earnings catch up, though long-term investors may find it a buying opportunity.
