Xylem Shares Climb on Strategic Moves as Trading Volume Surges to 488th Rank

Xylem (XYL) surged 2.96% on Sept. 11, with trading volume hitting $230 million—a 48.09% jump from the previous day. The water technology company ranked 488th in volume among listed equities, indicating heightened investor interest amid market volatility.

Recent developments highlight Xylem’s strategic focus on expanding its industrial water solutions portfolio, including a major contract win in the energy sector. The company also announced a partnership with a European infrastructure firm to develop smart water management systems, reinforcing its long-term growth narrative. Analysts noted these moves align with sector-wide demand for sustainable water technologies, though no immediate earnings guidance was disclosed.

I understand you’d like to evaluate a daily-rebalanced portfolio that, each trading day, buys the 500 stocks with the highest dollar trading volume and holds them for one day, covering the period 2022-01-01 to today. At the moment, the toolset available in this interface is geared toward single-ticker or single-event back-tests; it does not yet support multi-asset, cross-sectional strategies (e.g., “top-N by volume”) in one call. As a result, I’m unable to run the exact portfolio back-test you requested through the built-in engine.

Two practical ways forward are: 1. Narrow the scope to a single security or to an ETF that approximates the high-volume universe (for example, a large-cap ETF such as SPY or VTI), and back-test an event or timing strategy on that instrument; or 2. Export the necessary data (daily volume and prices for the entire universe), after which you could perform the ranking and portfolio construction offline. Please let me know which direction (or any alternative) you’d prefer, and I’ll proceed accordingly.
