# Quantum Computing Stocks Rally in Overnight Session: IONQ Up Nearly 3%, QBTS Surges Over 3%

During the overnight session on Wednesday (July 29, ET), the quantum computing sector saw a broad-based advance, with major stocks reversing earlier losses or extending gains. As of press time, all four primary tickers in the sector were trading higher, indicating a shift in market sentiment compared to the regular session.

Specifically, **IONQ (IONQ.US)** was last traded at $32.90 in the overnight session, up approximately 2.84% from its previous close of $31.99, marking a gain of **nearly 3%**. **QBTS (QBTS.US)** showed even stronger momentum, rising to $16.69, which represents a 3.15% increase from its previous close of $16.18, or **over 3%**.

Meanwhile, **RGTI (RGTI.US)** and **QUBT (QUBT.US)** also participated in the rally. RGTI gained 2.50% to trade at $13.55, while QUBT advanced 2.05% to $7.45. Although their gains did not cross the 3% threshold for headline rounding, their positive performance contributed to the sector's overall upward trend. Despite lower liquidity typical of overnight trading, buying interest was evident, driving a valuation recovery across the quantum computing landscape.
