JD.com Surges 3.4% on Supply Chain Gains Ranks 165th in Market Activity

On October 1, 2025, JD.com (JD) closed with a 3.40% gain, achieving a trading volume of $0.76 billion and ranking 165th in market activity. The stock's performance coincided with a broader market rebound, though its relative strength highlighted specific catalysts tied to operational developments.

Recent reports indicated progress in JD's supply chain optimization initiatives, with updated logistics infrastructure showing improved efficiency metrics. Analysts noted that these improvements, coupled with seasonal demand trends for Q4, contributed to renewed investor confidence. The company's strategic focus on cost management also drew attention, as investors weighed its impact on margin sustainability amid competitive pressures.

Back-testing evaluations revealed constraints in assessing multi-ticker strategies within the current platform. The system supports single-security analysis but lacks tools for cross-sectional ranking across large portfolios. Two alternatives were proposed: using a broad-market ETF as a proxy for liquidity cohorts, or exporting data externally to calculate synthetic returns. The former offers speed but introduces approximation errors, while the latter maintains accuracy at the cost of workflow complexity.

For those seeking to evaluate the high-liquidity basket approach, the ETF-based approximation provides immediate directional insights. Conversely, the custom portfolio method ensures alignment with the original strategy parameters, albeit requiring external data processing. Both options remain viable depending on the desired balance between precision and execution efficiency.
