Rigetti Stock (+13%): Quantum Sector Rally Ignites Speculative Chase

Rigetti Computing surged over 13% on December 22, 2025, amidst a broader rally in quantum computing stocks. The move was characterized by a significant spike in trading volume, suggesting aggressive buying interest. But with no direct company-specific news catalyst, is this a sustainable shift in institutional sentiment or simply a speculative, retail-driven chase?

The rally was not driven by a fundamental change at Rigetti itself, but rather by a sector-wide speculative fervor. Thematic interest in quantum computing appears to be the primary driver.

• No major press releases or SEC filings from Rigetti on the day of the move.
• Broader quantum computing sector experienced a surge, with competitors also seeing double-digit gains.
• The move is being attributed to anticipation of a bull run in the sector for 2026.

Trade Mechanics & Money Flow

Trade Mechanics: What Happened?

The trading mechanics behind the 13% surge point towards a speculative chase, likely amplified by short-covering.

• Trading volume on the day was 59.96M shares, significantly higher than the average volume of 36.75M.
• Short interest in Rigetti stood at 13.24% of the float in the last reporting period.
• With a short interest ratio of 1.1 days to cover, a sharp price increase could trigger a rapid unwind of short positions.

How Is The Money Flowing?

While institutional ownership has been increasing, the aggressive nature of the single-day move suggests a significant retail footprint, likely chasing momentum in a high-beta name.

• Institutional ownership increased to 54.5% in September 2025 from 44.5% in June 2025.
• Major holders include Vanguard, BlackRock, and D. E. Shaw.
• The stock is popular among retail investors, with public companies and individual investors owning a significant portion of the shares.

What Next?

FADE. While the long-term thematic of quantum computing is compelling, this specific move appears untethered to any new fundamental catalyst. The high volume spike and sector-wide speculative nature suggest a high probability of a near-term retracement. Watch the $24.19 level, the low of the day on December 22nd. A break below this level would indicate a failure of the speculative rally and could trigger further downside as short-sellers regain control and early chasers are forced to liquidate.
