On June 5, POET Technologies fell 8.05% in regular trading, trading at $13.805/share, with trading volume of $127 million.

On the news front, the optical communication and semiconductor sectors extended the prior session's pullback, with broad-based selling pressure persisting. Ciena's disappointing third-quarter revenue guidance — with the midpoint falling below elevated market expectations — continued to weigh on sentiment across the optical networking space. Additionally, Broadcom's post-earnings decline, driven by its CEO's refusal to raise fiscal 2027 AI revenue guidance despite strong current results, further dragged down AI-related names. Within the sector, Micron Technology fell 5.16%, Advanced Micro Devices fell 5.37%, Marvell Technology fell 5.34%, Broadcom fell 4.18%, and NVIDIA fell 2.72%.

POET had rallied sharply over multiple consecutive sessions prior to this week's correction, with rapid short-term gains intensifying profit-taking pressure amid the sector-wide retreat.
