Eos Energy’s $340M Trading Surge Fails to Lift Price as It Falls to 352nd in Volume Ranking

On October 2, 2025, Eos Energy (EOSE) recorded a trading volume of $0.34 billion, marking a 38.73% increase from the previous day’s activity. The stock closed 0.08% lower, ranking 352nd in terms of trading volume among listed equities.

Recent market dynamics suggest mixed sentiment toward Eos Energy. Analysts noted that the surge in trading volume could reflect heightened investor scrutiny following recent operational updates, though the modest price decline indicates lingering caution. The stock’s performance appears decoupled from broader market trends, with no direct correlation to sector-specific catalysts reported in the same period.

To run this back-test rigorously I first need to pin down a few practical details that weren’t specified explicitly: Trading universe – Do we focus on U.S. listed equities only, or a different (or broader) market? Are any liquidity / listing filters (e.g., minimum price, primary share class, etc.) required in addition to the “top-500 by volume” screen? Signal & execution convention – Which price do we use for entry and exit? Buy at today’s close and sell at tomorrow’s close (typical end-of-day re-balancing), or Buy at tomorrow’s open and sell at tomorrow’s close (intraday hold), or another convention? Should we assume equal-weighted allocation across the 500 names each day? Back-test mechanics – Slippage / transaction costs: should we include a default assumption (e.g., 2 bps each way), or ignore them? Cash management between daily exits and re-entries (generally treated as 100 % reinvested). Please let me know your preferences on these items; once confirmed I can proceed to pull the necessary data and run the back-test from 2022-01-01 to the present date.
