What Propelled These 10 Firms’ Double-Digit Gains?

8. D-Wave Quantum Inc. (NYSE:QBTS)

D-Wave Quantum saw its stock prices jump by 13.32 percent on Friday to close at $7.91 each as investors gobbled up shares ahead of its earnings performance on Thursday, May 8, 2025, while placing bets in line with the overall market optimism.

Friday’s rally suggested that investors shunned recent reports that the company was being targeted by a short seller, which criticized its core technology, quantum annealing, as already at the “commercial dead end” that has already been abandoned by the rest of the industry.

According to the short seller, Kerrisdale, the company’s strategy, which emphasizes hybrid solvers for optimization problems, was misleading, saying that it was obscuring the actual mix of classical and quantum computing in its offerings to customers while charging a significant premium for the quantum branding.

D-Wave Quantum Inc. (NYSE:QBTS) has yet to respond to the allegations.
