Coinbase Falls 4.69% Despite $2.75B Volume Surge Ranks 32nd in U.S. Turnover Amid Regulatory Scrutiny

On September 25, 2025, Coinbase Global (COIN) reported a 4.69% decline despite a surge in trading volume to $2.75 billion, ranking 32nd among U.S. stocks by daily turnover. The exchange’s market performance followed a period of heightened regulatory scrutiny and mixed institutional investor sentiment, though no direct corporate announcements impacted its shares on the day.

Analysts noted that the price drop aligned with broader crypto sector volatility, as macroeconomic concerns and uncertain regulatory frameworks continued to weigh on investor confidence. However, Coinbase’s volume spike indicated sustained institutional and retail interest in its platform, particularly amid speculation about potential derivatives product launches.

To evaluate the viability of a volume-weighted trading strategy involving Coinbase, further clarification is required on portfolio construction. Key parameters include the universe of stocks (e.g., Russell 3000 vs. broader listings), rebalancing frequency, and return calculation methods. A custom back-test would necessitate daily basket recreation based on real-time volume data, which may require extended processing time and additional data integration.

For a 500-stock daily-rotating strategy, confirmation is needed on whether to apply equal weighting to all selected assets and whether to ignore transaction costs in return calculations. Once these parameters are finalized, the back-test can proceed with precise data retrieval and execution steps.
