Amazon's 4.99% Slide Driven by Tech Exodus as $15.94B Volume Ranks Fourth on Market Correction Day

On October 10, 2025, Amazon (AMZN) closed at a 4.99% decline, with a trading volume of $15.94 billion—the fourth-highest on the day. The selloff followed a broader market correction amid shifting investor sentiment toward growth stocks. While no direct earnings or strategic updates were cited in accessible reports, the move aligned with broader sector rotation patterns observed in tech-heavy indices.

Analysts noted that the drop coincided with reduced liquidity in high-beta assets, as macroeconomic concerns tempered speculative trading. Institutional outflows in large-cap tech names were reported, though no Amazon-specific catalysts such as product delays, regulatory actions, or executive changes were identified in available materials. The stock's performance remained decoupled from peer movements, suggesting position adjustments rather than fundamental triggers.

To run this back-test rigorously, several parameters require clarification: the security universe (e.g., S&P 500 constituents vs. broader exchanges), ranking metrics (dollar volume vs. raw share volume), portfolio weighting rules, and transaction cost assumptions.
