# Quantum Computing Sector Falls Broadly Intraday, IONQ Down Over 5%, QBTS Near 8%

During intraday trading on Tuesday (July 29), the quantum computing sector faced significant selling pressure, with all major constituents moving lower. As of 3:45 PM ET, all four component stocks in the sector closed down, led by RGTI, followed closely by QBTS and IONQ, indicating a clear shift in market sentiment.

Specifically, **IONQ.US** dipped to a low of $32.00 during the session and is currently trading at $32.07, down **5.34%** from the previous close. **QBTS.US** showed greater weakness, trading at $16.255 with a decline of **7.83%**. **RGTI.US** suffered the steepest drop, falling **9.16%** to $13.19. **QUBT.US** also participated in the selloff, down **4.66%** to $7.36. In terms of volume, trading activity remained robust across the board, with IONQ's regular session turnover exceeding $615 million, reflecting significant divergence among investors at current levels.

Analysts note that volatility in the quantum computing sector has intensified recently. Today's broad intraday pullback may be influenced by shifting expectations for macro liquidity and a revaluation of growth-oriented technology stocks. Investors are advised to monitor technical support levels and the rollout of industry catalysts, as the sector is likely to maintain a pattern of high-volatility oscillation in the near term.
