Equinix Surges 2.10% on $380M Volume Spike, Ranks 307th in Trading Activity

On October 8, 2025, Equinix (EQIX) surged 2.10% to close at $... as trading volume hit $0.38 billion, a 68.95% increase from the prior session, ranking it 307th among stocks by volume. The data center operator’s performance reflects strong liquidity and investor interest in the sector amid evolving market dynamics.

Analysts noted that Equinix’s volume spike aligns with broader institutional positioning in data infrastructure equities. The stock’s elevated volume suggests potential accumulation or rebalancing activity, though specific catalysts remain unconfirmed. Market participants are monitoring capacity utilization trends and enterprise demand for cloud connectivity, which historically influence the stock’s momentum.

To run this back-test rigorously I need to pin down a few practical details: 1. Market universe • Which exchange(s) should the stock pool come from – e.g. all primary-listed U.S. equities, or a narrower universe such as the S&P 1500 constituents? • Do ADRs / ETFs stay in or out? 2. Ranking convention • Use the prior day’s volume (avoids look-ahead bias) and open the position at the next day’s open, then exit at that day’s close – does that match your intent? 3. Weighting & turnover cost • Equal-weight within the daily top-500? • Apply any slippage / commission assumptions? 4. Tool limits Fetching and rebalancing 500 stocks every day for three years is doable, but only after we agree on the precise ticker universe (so I can bulk-pull volume & price data for each name). Please let me know your preferences on the four points above (especially #1). Once I have that, I can start the data pulls and run the back-test.
