Amazon's 14.9% Jump Lifts the Dow While Apple Drags It Back

Amazon surged 14.9% following its Q2 earnings report, powered by AWS cloud revenue growth of 37% year-over-year. The move added 208 points to the Dow Jones Industrial Average, marking one of the largest single-session contributions from a tech mega-cap this year.

Apple moved in the opposite direction, falling 9.4% despite posting solid Q3 results. Management cited chip supply constraints in forward guidance, spoiling an otherwise clean beat. The drop wiped 188 points from the Dow, nearly offsetting Amazon's lift.

The split underscores the current market dynamic: AI-exposed cloud infrastructure businesses command premium valuations, while hardware-dependent revenue streams face skepticism. AWS's 37% growth rate signals sustained enterprise demand for cloud compute capacity, a tailwind as artificial intelligence workloads scale. Apple's supply-chain caution raises questions about iPhone production heading into the holiday quarter.

Most stocks outside mega-cap tech finished lower, reinforcing concentration risk in major indexes.
