Quantum Surge Lifts Rigetti Computing to 15th in Trading Activity on 44% Volume Jump

Rigetti Computing (RGTI) saw a 0.57% increase in its stock price on September 24, 2025, with a trading volume of $4.57 billion, marking a 44.13% surge from the previous day. This elevated volume ranked the company 15th in overall trading activity across the market, reflecting heightened investor interest in the quantum computing sector.

Recent developments highlight a strategic focus on advancing quantum hardware capabilities, with updates on R&D progress and partnerships in quantum cloud services. Analysts noted that the company's emphasis on scalable quantum processors and potential applications in cryptography and optimization could drive long-term value. However, short-term price movements remain tied to macroeconomic signals, including interest rate expectations and sector-specific capital allocation trends.

The back-test framework for evaluating high-activity stock strategies requires precise parameters, including market universe scope, weighting methodologies, transaction timing, and cost assumptions. Rigetti’s inclusion in actively traded lists underscores its role as a focal point for algorithmic trading strategies, though execution outcomes depend on the defined rules for entry/exit pricing and rebalancing mechanics.

To build an accurate back-test for “buy the 500 most‐actively traded stocks each day and hold them for one day,” I need to pin down a few practical details: Market universe, weighting & rebalancing mechanics, corporate-action handling, transaction costs, and benchmark preference. Once these points are clarified, I can generate the data-retrieval plan and run the back-test.
