Core Viewpoint - Costco's business is performing well, but its stock faces challenges due to high valuation and lack of catalysts [1][2] Group 1: Business Performance - Costco's revenue grew approximately 8% for both Q4 and the full fiscal year, with comparable sales increasing by 6.4% in Q4 and 7.6% for the full year [3] - There is a slight slowdown in comparable store sales growth, with November's growth at 6.4%, down from 6.8% in October [4] Group 2: Membership Fees and Catalysts - Costco raised membership fees in the U.S. and Canada, contributing to a 14% increase in membership fees in Q4 of fiscal 2025 [6] - The company is unlikely to raise membership fees again for several years, limiting potential profit growth from this source [7] Group 3: Valuation Concerns - Costco's stock trades at about 49 times earnings, significantly higher than the S&P 500's P/E of 25, creating high expectations for performance [9] - The company's business model focuses on passing savings to customers, making rapid margin expansion unlikely [10]
