Making Sense of Q2 Earnings Expectations

Core Viewpoint - The quarterly reports from Costco and AutoZone have initiated the Q2 earnings season, with Costco showing strong performance against consensus estimates, while broader expectations for the S&P 500 indicate a slowdown in earnings growth compared to Q1 [2][3][6]. Costco Performance - Costco reported earnings, revenues, and same-store sales that exceeded consensus estimates, with same-store sales increasing by +8% for the quarter, excluding gasoline and foreign exchange impacts, following a +9.1% growth in the previous period [3]. - The high single-digit growth in Costco's non-food merchandise suggests a competitive advantage over other retailers like Walmart and Target, likely due to its affluent customer base and potential market share gains [4]. - Despite tariff challenges, Costco's management noted that most merchandise is sourced domestically, with only about 25% of U.S. sales reliant on imports [5]. Broader Market Expectations - For Q2, S&P 500 earnings are expected to rise by +5.4% year-over-year, with revenues increasing by +3.7%, marking a significant deceleration from the +12% earnings growth and +4.7% revenue growth seen in Q1 [6]. - Since April, Q2 earnings estimates have been cut for 15 of the 16 Zacks sectors, with the most significant reductions in Transportation, Autos, Energy, Basic Materials, and Construction sectors [7]. - The Tech and Finance sectors, which contribute over 50% of S&P 500 earnings, have also seen downward revisions, although the Tech sector's revisions have stabilized recently due to easing tariff uncertainties [8][10][11].
