Rigetti Computing (NASDAQ: RGTI), a prominent player in the quantum computing sector, saw its stock plummet 5.12% in pre-market trading on Friday. This significant drop comes on the heels of a major insider stock sale by the company's Chief Technology Officer (CTO), David Rivas.

According to recent insider activity reports, Rivas sold 44,815 shares of Rigetti Computing. This substantial divestment by a key executive has likely triggered concerns among investors, leading to the sharp pre-market decline. Insider sales are often closely watched by market participants as they can sometimes signal a lack of confidence in the company's near-term prospects.

The quantum computing industry has been experiencing volatility in recent weeks, with various companies in the sector seeing significant price movements. While some quantum computing stocks have shown gains, Rigetti's pre-market plunge stands out, potentially exacerbated by the insider selling news. As the market opens, investors will be closely monitoring Rigetti's stock performance and any further developments or statements from the company regarding this significant insider transaction.
