Zillow Slips to 438th in U.S. Trading Activity Amid 37.47% Volume Drop

Zillow Group (Z) closed on September 24, 2025, with a 0.29% decline in share price. The stock saw a total trading volume of $0.23 billion, marking a 37.47% drop from the previous day’s volume. This placed Zillow at rank 438 in terms of trading activity across U.S. markets.

Recent market analysis indicates mixed sentiment toward the real estate technology sector. While Zillow’s core home valuation tools remain critical to industry operations, broader macroeconomic uncertainties have dampened investor confidence. Analysts note that the company’s reliance on digital advertising revenue and its exposure to mortgage rate fluctuations continue to weigh on long-term growth projections.

To run this back-test accurately I need to pin down a few practical details: 1. Market universe • All U.S. exchange-listed common stocks, or a narrower list (e.g., S&P 500 constituents)? 2. Ranking rule • Use the previous trading day’s total volume to choose today’s top-500? 3. Portfolio construction • Equal-weight each of the 500 names? 4. Transaction assumptions • Ignore commissions/slippage, or apply some standard cost? 5. Benchmark (if any) you’d like me to show side-by-side? Once I have those details I can generate the entry / exit signals, feed them into the back-test engine and share the results.
