Quantum computing stocks are having one of those days. IonQ Inc. (IONQ) stock is moving lower in Thursday pre-market trading as investors pull back from quantum computing and high-growth technology names, the kind of stocks that tend to swing harder than the broader market.
It is not just a quantum story. Broader index futures point downward too, with Nasdaq futures falling 1.52% and S&P 500 futures declining 0.80%.
A wider selloff across artificial intelligence and technology stocks is also pressing on IonQ. Uncertainty surrounding Nvidia Corp. (NVDA) CEO Jensen Huang has pressured companies throughout the AI ecosystem.
As a result, market participants are reassessing valuations for high-growth technology names alongside quantum computing stocks. When the AI trade sneezes, the speculative corners of tech tend to catch a cold.
Sector-wide weakness followed third-quarter fiscal 2026 earnings from peer Rigetti Computing Inc. (RGTI) on Tuesday, after the company missed estimates.
During Rigetti's earnings call, CFO Jeffrey Bertelsen attributed higher sequential capital expenditures, meaning funds spent on physical equipment and facilities, to investments in larger-capacity dilution refrigerators and equipment for its Fab-1 facility.
Bertelsen noted these purchases support Rigetti's three-year plan to reach the 1,000-qubit level. That is the quantum equivalent of building a bigger factory before you have the orders, and investors are clearly weighing the cost of that ambition.
IonQ is trading above its 20-day SMA ($31.57) but remains in a broader downtrend, sitting 10.1% below its 50-day SMA ($36.69) and 20.3% below its 200-day SMA ($41.38). That stack of longer moving averages overhead is why rallies have had trouble turning into sustained uptrends, even when the stock bounces.
RSI is at 51.30, which signals neutral momentum, neither stretched to the upside nor washed out to the downside. In plain terms, RSI helps gauge whether buying or selling has become overdone, and this reading suggests traders are still treating the recent move as more of a range than a breakout.
The bigger-picture trend damage is still visible in the bearish crossover structure: the 20-day SMA is below the 50-day SMA, and the death cross that formed in August (50-day below the 200-day) continues to frame the longer-term bias. The stock's 12-month performance (down 32.83%) lines up with that longer-term pressure.
IONQ Stock Price Activity: IonQ shares were down 4.08% at $32.67 during premarket trading on Thursday, according to market data.
