Rigetti Computing Stock Plunges 2.87% Amid Quantum Sector Caution Ranks 21st in U.S. Trading Activity

On September 26, 2025, Rigetti Computing (RGTI) closed with a 2.87% decline, trading at a volume of $3.2 billion, a 20.74% drop from the previous day. The stock ranked 21st in trading activity among U.S. equities. Despite elevated liquidity, the downward trajectory reflects broader market dynamics and sector-specific pressures.

The decline aligns with cautious investor sentiment toward quantum computing equities amid macroeconomic uncertainty. Analysts note that RGTI’s performance remains tied to macroeconomic indicators, with its valuation sensitive to shifts in risk appetite and capital allocation trends. The sector’s volatility underscores the challenge of balancing long-term growth potential with near-term execution risks.

Recent developments highlight the stock’s susceptibility to liquidity-driven corrections. While RGTI maintains a leadership position in quantum hardware innovation, its market exposure amplifies sensitivity to broader equity market rotations. Institutional positioning and short-term technical indicators suggest further consolidation before a potential directional move.

To validate the methodology for the back-test, confirmation is required on the market universe scope, portfolio rebalancing frequency, transaction cost assumptions, and price basis for return calculations. Additional constraints such as liquidity filters or risk controls must also be defined to ensure the strategy’s integrity.
