Why the price moved
Sector rotation, not fresh company news.
QUBT rallied with IONQ, RGTI and QBTS after three declining sessions. The volume jump supports a risk-on move. The latest company earnings release remains the Aug. 10 Q2 report.
Next-week decision points
First support$8.14
Recent high$9.18
Balance-sheet anchor$5.74/share
A close above $9.18 would strengthen the rebound. A break below $8.14 would return focus to execution, spending and order conversion.
