Occidental’s OXY Shares Rally 1.01% on Mid-Tier Liquidity Amid 20.43% Volume Drop and Energy Transition Push

On September 24, 2025, Occidental Corporation (OXY) traded with a volume of $0.33 billion, reflecting a 20.43% decline from the previous day’s activity. The stock closed with a 1.01% increase, positioning itself within the mid-tier of market liquidity rankings. The move suggests selective buying interest amid broader sector consolidation trends.

Recent developments highlight Occidental’s strategic positioning in the energy transition landscape. The company’s expanded focus on carbon capture and blue hydrogen projects aligns with regulatory tailwinds in emissions reduction targets. Analysts note that operational efficiency gains from recent asset rationalizations could underpin near-term earnings resilience despite volatile commodity pricing environments.

To set up this back-test rigorously I need to pin down a few practical details that aren’t yet specified: 1. Universe • Should the “top-500 by trading volume” be drawn from all U.S. listed common equities, from a specific index (e.g., Russell 3000, S&P 1500), or from another universe? 2. Portfolio construction • Do we hold the selected 500 names equally weighted each day, or apply another weighting (e.g., volume- or cap-weighted)? • Rebalance frequency is daily (buy at today’s open, sell at tomorrow’s open/close). Please confirm entry/exit price convention—open-to-open, open-to-close, or close-to-close. 3. Costs & constraints • Should we include transaction costs/slippage? • Any risk-control rules (stop-loss, max drawdown, etc.) or assume a pure buy-and-hold-for-1-day approach? Once those points are clarified I can generate the data-retrieval plan and run the back-test.
