Rigetti Computing Shares Surge 18.59 on 4.99B Trading Volume Ranking 16th Most Active

On October 2, 2025, Rigetti Computing (RGTI) surged 18.59% to close its most active session, with a trading volume of $4.99 billion—a 83.79% increase from the previous day—ranking 16th in market activity. The stock’s sharp rise followed a strategic update highlighting advancements in quantum cloud infrastructure, which analysts noted could accelerate enterprise adoption of hybrid quantum-classical solutions.

Market participants observed heightened institutional interest, driven by renewed optimism over RGTI’s roadmap for error mitigation in quantum processors. A key catalyst was the company’s partnership with a major European research consortium to co-develop application-specific quantum algorithms, signaling potential cross-border commercialization opportunities. Short-term traders also capitalized on the momentum, with options activity showing a 35% surge in call options relative to puts.

To deliver an accurate back-test we need to pin down a few practical details: 1. Market universe • Which exchange(s) should be included when we rank by volume – U.S.-listed equities only (NYSE + NASDAQ), or a different universe? 2. Execution convention • Do we a) rank stocks after the close, then buy them at next day’s open and liquidate at that day’s close (T+1 holding), or b) rank intraday and transact at the same day’s close? 3. Rebalancing / sizing • Equal-weight each of the 500 names every day, correct? • Any transaction-cost or slippage assumption? Once we confirm these points I can generate the daily trade list, run the back-test and present the performance report.
