Rigetti Computing Inc is trading at $21.25 (-6.37%) as the stock pulls back after an 8.20% jump on June 15 and ongoing volatility in the quantum computing sector. - The decline follows recent insider selling, with a director disposing of warrants on June 15 and June 12. - Profit-taking after a recent rally and a sector-wide re-evaluation following Quantinuum's recent IPO also appear to be contributing factors.
