Coupang Shares Climb 0.71 as 0.3 Billion Dollar Volume Ranks 420th Amid Logistics Expansion and Cost Strategy Moves

On October 1, 2025, Coupang (CPNG) closed with a 0.71% gain, trading with a total volume of $0.3 billion, ranking 420th in market activity for the session. The e-commerce giant’s shares edged higher despite mixed broader market sentiment, with analysts attributing the performance to recent strategic updates and investor reassessment of its long-term growth potential.

Recent developments highlighted include Coupang’s announcement of expanded logistics partnerships to bolster delivery efficiency, a move seen as critical for maintaining its competitive edge in the South Korean market. Additionally, the company reiterated its commitment to cost optimization initiatives, signaling potential margin stabilization amid ongoing macroeconomic pressures. These factors contributed to a cautious bullish outlook among institutional observers, though short-term volatility remains tied to execution of its operational roadmap.

To run this back-test rigorously I need to pin down a few practical details: 1. Universe • Do you want to rank every U.S. common stock (NYSE + NASDAQ + AMEX), or a narrower list such as the S&P 1500 / Russell 3000 constituents? • Should ADRs, ETFs and penny stocks be included or excluded? 2. Volume definition • Rank by share volume (shares traded) or by notional volume (dollar value traded)? 3. Trade timing • Because today’s volume is only known after the close, the usual convention is: – Day t: compute the ranking after the close. – Day t + 1: enter positions at the open, exit at the close (1-day hold). • Is this acceptable, or would you prefer another convention (e.g., buy at today’s close and sell tomorrow’s close)? 4. Transaction costs • Should we include commissions/slippage? If yes, please specify. Once these points are confirmed I can build the data-retrieval plan and run the back-test.
