October 1 2025 The Stock Slumps to $320M in Volume Ranking 389th Amid Dwindling Liquidity

On October 1, 2025, The saw a trading volume of $0.32 billion, representing a 21.81% decline from the previous day's activity. This placed the stock at rank 389 in terms of trading volume across the market. Meanwhile, private equity firm Carlyle Group (CG) experienced a 3.06% drop in its share price.

Recent developments indicate shifting investor sentiment toward The, with reduced liquidity contributing to its mid-table volume ranking. Analysts note that broader market dynamics, including sector rotation and macroeconomic uncertainty, may be influencing short-term trading patterns. However, no direct corporate announcements or earnings reports were cited as catalysts for the volume contraction.

To deliver a rigorous back-test I need to pin down a few practical details that aren't completely specified yet. Please let me know (or confirm) the following so I can build the data-retrieval plan and run the engine correctly:

1. Universe • All common stocks listed on NYSE, NASDAQ & NYSE American (≈ 6,000 symbols), or a narrower list? • If you have a preferred universe file / index, please specify.

2. Ranking & trading logic (to avoid look-ahead bias) • Typical practice is: a) Rank stocks by yesterday’s dollar volume (shares × close) after the close. b) Buy the 500 highest-ranked names at today’s open. c) Exit all positions at today’s close (holding period = 1 trading day). • Is this acceptable, or would you rather use an end-of-day “buy at close, sell next day close” convention?

3. Transaction costs & slippage • Should I assume zero costs, or apply a cost assumption (e.g. $0.005/share or 2 bps each side)?

4. Cash handling • Equal-weight the 500 names each day with full capital deployment? • Any leverage or cash drag considerations?

If the above default assumptions are fine, just say “proceed” and I’ll run the back-test from 2022-01-03 to today. Otherwise, please adjust any item(s) and I’ll incorporate your preferences.
