Nu Holdings Climbs 0.71% on $680M Volume Ranking 164th as Analysts Stress Precision in Strategy Parameters

Nu Holdings (NU) closed with a 0.71% gain on Sept. 11, 2025, with a trading volume of $680 million, ranking 164th in market activity for the session. The stock's performance aligns with ongoing investor scrutiny of liquidity dynamics in mid-cap equities.

Analysts highlight the critical need for precise parameters in backtesting strategies involving volume-based screening. Key variables include the definition of "volume"—whether measured by share count or dollar value—and the geographic scope of the stock universe. These factors directly influence the construction of high-volume watchlists and subsequent portfolio rotation mechanics.

For rigorous testing, two foundational elements require explicit definition: (1) the stock universe (U.S.-listed common stocks vs. global exposure) and (2) the volume metric (share volume for "top-volume" screens vs. dollar volume calculations). Establishing these parameters enables accurate measurement of daily returns through systematic portfolio rebalancing.

Once the universe and volume measure are confirmed, a test can be executed by constructing a daily top-500 list, rotating the portfolio each trading day, and tracking close-to-close returns from Jan. 3, 2022, to the present. Alternative configurations, such as adjusting the number of names or holding periods, can be accommodated upon request.
