Wayfair's (W) 5.82% Plunge and $350M Volume Surge Rank It 355th Most Liquid U.S. Stock

On October 10, 2025, Wayfair (W) closed at a 5.82% decline, marking its third consecutive session of negative momentum. Trading volume surged to $350 million, a 47.83% increase from the prior day, ranking it 355th among U.S. stocks by liquidity. The drop followed a mixed earnings update highlighting margin pressures despite improved order growth in key furniture categories. Analysts noted the volume spike reflected heightened short-term trading activity, though institutional ownership trends remained neutral in the latest 13F filings.

Recent filings revealed a strategic shift in inventory management, with the company accelerating returns processing to reduce warehouse costs. This operational pivot coincided with a 12% increase in customer acquisition costs compared to the same period last year. While e-commerce traffic metrics showed resilience in the home furnishings segment, supply chain bottlenecks in imported goods continued to weigh on gross profit margins. The stock's technical profile remained bearish, with RSI indicators suggesting potential for further downside correction below key support levels.

To run this back-test accurately, I need to pin down a couple of practical details: 1. Stock universe • All U.S. listed common stocks (NYSE + NASDAQ + NYSE-Arca) – default, or • A specific list/index you have in mind (e.g., Russell 3000, S&P 500)? 2. Trade-day timing (to avoid look-ahead bias) • Rank by volume on day T (using the full day’s data). • Buy the top 500 at the open of day T + 1. • Hold for one session. • Exit at the close of day T + 1. Is that execution schedule acceptable, or would you prefer a different convention? 3. Transaction costs (if any) • Assume zero commissions/slippage (default), or • Specify per-trade cost or basis-point slippage. Once I have these points confirmed, I can pull volume data, build the daily signal file, and run the back-test from 2022-01-03 through the latest trading day.
