Costco Wholesale Corporation remains a high-quality, dividend growth stock but trades at an excessive forward P/E above 45x, justifying a hold rating. COST's Q3 saw double-digit EPS and revenue growth, fueled by strong membership gains and benefits from higher fuel prices, but comparable sales growth is slowing. Gross margins declined year-over-year due to inflationary pressures and price reductions, while management plans 30+ net new warehouse openings annually.
