Apple Shares Climb 1.81 on 14.07 Billion Volume Rank Third in Daily Trading Activity

Apple Inc. (AAPL) saw a 1.81% rise in its stock price on Sept. 25, 2025, with a trading volume of $14.07 billion, marking a 31.81% increase from the previous day. The company’s shares ranked third in trading activity for the day, reflecting heightened investor interest.

Recent market dynamics suggest a focus on Apple’s ecosystem-driven strategies, including anticipated product launches and service revenue growth. Analysts noted that the stock’s performance aligns with broader tech sector trends, though Apple’s unique position in consumer electronics and software integration provides a distinct edge. Short-term momentum appears supported by strong earnings visibility and supply chain stability.

To build an accurate back-test, two practical details require confirmation: the stock universe (e.g., U.S.-listed shares on NYSE or NASDAQ) and weighting methods for the daily top-500 list (e.g., equal weight or volume-weighted). The framework involves ranking stocks by prior-day trading volume, entering the 500 names at the next open, and exiting them at the day’s close. Performance would be measured from Jan. 3, 2022, to the current date. Adjustments to these parameters are welcomed for precise results.
