On June 25, Silicon Motion Technology rose 5.7% overnight, trading at $340.01/share. The rally was driven by a continued escalation of the storage sector supply shortage narrative alongside strong sector-wide momentum.

On the news front, the company's Senior Vice President Nelson Duann previously warned that the NAND shortage is just the beginning, with data centers absorbing 70-80% of production capacity. New fabrication plants under construction are not expected to deliver meaningful output until at least the end of next year, suggesting supply constraints will persist through at least that timeline. On the institutional side, CITIC Securities initiated coverage with a Buy rating, highlighting Silicon Motion as the global leader in independent SSD controller chips, benefiting from its 6nm PCIe 5.0 controller technology advantage and market share gains as NAND original manufacturers exit the space.

Among sector peers, Micron Technology surged 15.37%, reflecting pronounced sector sentiment resonance across storage-related equities.
