Rigetti Computing’s shares (ticker RGTI) rose about 16% during Wednesday’s session, placing the stock among the day’s most-mentioned gainers on several real-time market-tracking lists. The jump followed an early-morning move that pushed the price above its weekly value area, according to traders monitoring intraday charts. Market participants flagged a short interest near 20% of Rigetti’s free float and a surge in call-option activity as potential catalysts. Data watchers noted that open interest in bullish contracts increased alongside the rally, suggesting positions were being held rather than quickly closed out. Rigetti’s advance came as other actively traded tickers—JOBY, BHF, U and MDGL—also featured on ‘stocks on the move’ compilations. No company-specific news for Rigetti had been announced as of mid-afternoon, leaving the move largely attributed to technical factors and positioning in the options market.
