Quantum computing stocks surged in overnight trading. QUANTUM CORP rose 17%; D-Wave Quantum Inc. climbed 9%; Quantum Computing Inc., SEALSQ Corp rose 6%, Rigetti Computing rose 4%.

Bill Stone, chief investment officer at Glenview Trust, told Barron’s Tuesday that quantum computing may be “the next big thing,” but it is currently in speculation territory.

“It’s just too early in quantum computing to have any reasonable idea of future revenues and profits,” Stone said. “Most quantum companies have little revenue and lose money, so they are early in their life cycle.”

Some analysts are upbeat about quantum’s potential. B. Riley analyst Craig Ellis raised his price target on D-Wave stock to $9 from $4.50 on Tuesday while maintaining a Buy rating. In a research note, Ellis referenced comments made by D-Wave’s CEO in response to the “recent bellwether CEO market-moving remarks” and argued that D-Wave was already commercial.

Meanwhile, Benchmark analyst David Williams reiterated a $8 price target and Buy rating for the stock following the first customer purchase of an Advantage quantum computer from D-Wave. The sale “represents a major new revenue vector, but equally as important, a validation of accelerating market demand for quantum,” Williams wrote.
