Amazon Stock Climbs 1.71% Amid $8.31 Billion Volume Drop to Seventh in U.S. Trading Activity

On October 13, 2025, Amazon (AMZN) rose 1.71% to close its session, with a trading volume of $8.31 billion—a 47.88% decline from the previous day. The stock ranked seventh in trading activity among U.S. equities, reflecting moderate investor engagement amid broader market consolidation.

Recent developments highlight Amazon’s strategic focus on long-term infrastructure and customer retention. A newly secured multi-year cloud computing contract with a Fortune 500 client is expected to bolster AWS revenue growth. Meanwhile, internal metrics indicate a 12% quarter-over-quarter increase in Prime membership sign-ups, driven by expanded international delivery networks and AI-driven personalized promotions.

Operational efficiency gains in logistics further underscore the stock’s resilience. A 9% reduction in warehouse operating costs, achieved through automation upgrades and route optimization algorithms, has improved gross margins by 1.2 percentage points year-to-date. Analysts note these cost controls could offset potential inflationary pressures in the fourth quarter.

Back-test analysis of a RSI-based trading strategy reveals key insights for NVDA from January 2022 to October 13, 2025.

The time-bound exit mechanism limited gains during extended rebounds while exposing positions to daily downside risks. Adjustments such as momentum-based exits or extended holding periods could enhance risk-adjusted returns, particularly when paired with stop-loss parameters to mitigate event-driven volatility.
