Sunrun Shares Surge 4.74% on $240M Volume Spike Ranks 458th in Trading Activity

Sunrun (RUN) surged 4.74% on October 9, 2025, with a trading volume of $0.24 billion, marking a 60.39% increase from the previous day. The stock ranked 458th in trading activity among listed companies. The movement followed developments in the residential solar sector, though specific catalysts remain unconfirmed as market participants await further clarification from the company.

Analysts noted that the volume spike reflected heightened retail and institutional interest, potentially linked to recent regulatory discussions on renewable energy incentives. However, no direct announcements from Sunrun or its partners were cited in available reports, leaving the sustainability of the rally uncertain. The stock’s performance diverged from broader market trends, suggesting sector-specific dynamics at play.

To run this test rigorously I need to pin down a few practical details: 1. Universe • Which market/exchange(s) should we scan each day for the “top 500” by dollar-trading-volume? (e.g., all U.S. common stocks on NYSE + NASDAQ, only S&P 500 constituents, another universe, etc.) 2. Execution prices • Do we “enter” at that day’s close and exit at the next day’s close (classic close-to-close 1-day hold), or use next-day open for entry and next-day close for exit? 3. Weighting & capital • Equal-weight per stock each day? • Any position-level or portfolio-level constraints (e.g., max % of ADV, cash reserve)? 4. Friction • Should we include a transaction-cost assumption (commissions + slippage), or treat the back-test as frictionless? 5. Benchmark / risk controls (optional) • Would you like the results compared to a benchmark (e.g., SPY) or with any stop-loss / exposure caps? Once those points are set I can generate the daily trade list, run the 2022-to-present back-test, and share return, volatility, max drawdown, Sharpe, etc., together with the equity-curve visualization.
