SEALSQ Corp's stock plummeted 13.07% in Tuesday's pre-market trading session, adding to the losses seen in the previous day. The steep decline was part of a broader sell-off in quantum computing stocks, with shares of other companies like Quantum Corp and D-Wave Quantum also witnessing significant drops.

On Monday, SEALSQ Corp's shares tumbled around 10%, while D-Wave Quantum and Quantum Corp fell approximately 6% and 12%, respectively. The selling pressure in the quantum computing space intensified on Tuesday morning, with SEALSQ Corp extending its losses further.

While no specific reasons were provided for the outsized decline in SEALSQ Corp's stock compared to its peers, the overall bearish sentiment in the quantum computing sector seems to have weighed heavily on the company's shares. Investors appear to be taking profits off the table after a remarkable rally in quantum stocks throughout 2024.
