IonQ fell over 9% and was listed among the day's biggest decliners.

pressure may persist as investors rotate out of the sector

Evidence & confidence

$LCIDBearishMedium confidence
Context

Lucid also dropped more than 9% on the session, rounding out the top five losers.

Expected impact

downside risk remains unless broader market sentiment shifts

Evidence & confidence

The article treats Lucid as part of the collective optical‑sector sell‑off.

Market effects
