Is McDonald's Stock Worth Buying Amid Growth and Valuation Risks?

McDonald's reported 5% revenue growth and 7% operating income increase in the first nine months of 2026, supported by its franchise model and international expansion. However, weak U.S. comparable sales (-0.2% in Q3), persistent inflation, and competitive pressures from rivals like Chipotle and Burger King present near-term challenges. While strong cash generation supports capital expenditures and shareholder returns, the stock carries a Zacks Rank #4 (Sell) rating, suggesting investors should exercise patience until execution improves.
