POET Technologies Inc (POET) saw its stock price surge 6.01% during overnight trading, as the optical communication sector experienced a broad rally.

The movement appears to be driven by positive sentiment spreading across optical components stocks following Nvidia CEO Jensen Huang's endorsement of Marvell Technology, a maker of optical components. Huang suggested Marvell could become a $1 trillion company, which investors interpreted as a bullish signal for the entire opticals sector, including POET Technologies. Analysts noted that Huang's comments signaled the transition to co-packaged optics with graphics processing units is a "near-term build, not a someday story."

Additionally, the rally is tied to growing artificial intelligence infrastructure spending, with optical components being viewed as a critical building block for AI systems. Recent strong earnings results from Hewlett Packard Enterprise and Dell Technologies affirmed "rocketing" demand for AI infrastructure, which benefits companies in the opticals supply chain.
