**Quantum Computing Stocks Surge, But Valuation Raises Concerns**
As of December 12, 2023, quantum computing stocks have shown impressive gains, with IonQ (NYSE: IONQ) rising by 68%, Rigetti Computing (NASDAQ: RGTI) by 333%, D-Wave Quantum (NYSE: QBTS) by 568%, and Quantum Computing Inc. (NASDAQ: QUBT) by 89% over the past year. The potential economic value of quantum computing is estimated to be as high as $1 trillion by 2035 according to The Quantum Insider, while Boston Consulting Group anticipates between $450 billion and $850 billion by 2040.
However, analysts caution that these stocks are still in the early stages of commercialization, reflected in their extraordinarily high price-to-sales (P/S) ratios: IonQ at 156, Rigetti at 992, D-Wave at 315, and Quantum Computing Inc. at 3,144. Historical trends suggest that such elevated P/S ratios indicate potential bubbles, especially in sectors that have not yet achieved profitability or widespread utility. This raises concerns about the sustainability of their current valuations as the market heads into 2024.
