Is Quantum Computing (QUBT) Cheap On Book Value After Insider Selling?

Simply Wall St·11/03/2026 08:24:22
Listen to the news

Quantum Computing has seen its share price swing hard in recent years, which puts a spotlight on a simple question for anyone looking at the stock today. Is the current market value supported by what the company has built up on its balance sheet in book value terms?

  • Over the past 3 years the share price has risen by roughly 7x, which puts a lot of weight on whether the underlying equity in the business can justify that kind of move.
  • Heavy insider selling across major pure play quantum computing companies, including Quantum Computing, suggests management teams may be taking advantage of strong pricing, which can matter for how much book value investors are effectively paying for.

Is Quantum Computing Still Cheap on Book Value?

P/B fits Quantum Computing because the business is still loss making on free cash flow and investors are effectively paying for the balance sheet and future optionality rather than current profits. On this yardstick, Quantum Computing trades on a P/B of about 0.9x, compared with a Tech industry average near 2.0x and a peer group closer to 2.0x as well. That means the market price sits below the sector’s typical valuation for each dollar of equity and screens as undervalued on this single metric.

Insider selling highlighted in recent coverage matters here because it shows management reducing exposure even though the stock trades at a discount to book relative to peers. This raises questions about how durable that apparent value may be. For anyone considering the shares, the low P/B indicates that the market assigns a cautious price to Quantum Computing’s assets and future returns. You would need to weigh whether the technology roadmap and funding position justify a potential re-rating closer to industry norms. Explore the numbers behind Quantum Computing's P/B valuation.
