Why Quantum Computing Stocks Rocketed Higher on Thursday

Key Points

Not for the first time in their relatively brief existences, quantum computing stocks shot well higher in value on Thursday. That wasn't due to any fresh innovation, discovery, or major business move. Rather, it seemed to have more to do with some grand pronouncements by a single quantum company executive.

Nevertheless, as a writer, I can confirm that words have power, and these were powerful enough to lift the sector as a whole. Industry standard-bearers Quantum Computing (NASDAQ: QUBT), Rigetti Computing (NASDAQ: RGTI), and D-Wave Quantum (NYSE: QBTS) all saw their share prices inflate at double-digit rates. The stocks rose a respective 15%, 24%, and 26% on the day.

The king of quantum?

Those market-moving words came from the leader of one of their peers, IonQ (NYSE: IONQ). That morning, Barron's published an interview with the company's CEO, Niccolo de Masi, in which he waxed extremely bullish about the prospects for his business. This was clearly taken by the article's readers as likely prosperity for the wider quantum space.

De Masi is clearly not the shy and publicity-adverse type of corporate leader, as he made a series of grand pronouncements about IonQ.

In his eyes, the company is the quantum sector equivalent of graphics processing unit (GPU) king Nvidia or advanced processor specialist Broadcom. As such, IonQ's ultimate prominence and power will be imitated by businesses hoping to catch some of its magic.

In fact, added the executive, "they have always copied and followed us."

That isn't really accurate, as the varied quantum companies currently traded on the stock market are following different paths to hoped-for success. In IonQ's case, it's a "full-stack" business, aiming to provide hardware, the software that runs on it, and applications for control and access.

In a way, though, Quantum Computing, Rigetti, and D-Wave are followers. IonQ was among the first pure-play quantum companies to become publicly traded. That pedigree is a factor that has helped drive its market cap to over $11 billion at present. That dwarfs its three peers, as the most richly capitalized of the trio -- D-Wave -- is currently valued by investors at under $5.6 billion.

Rivers of red ink

Nevertheless, investors should always be wary of hype, especially when applied to an early-stage industry struggling to get on its financial feet -- like quantum.
