In September, we added a new position in the Information Technology sector with Sandisk Corporation (NASDAQ:SNDK), one of the largest manufacturers of storage devices, with solutions focused entirely on NAND flash memory. We believe SanDisk is a direct beneficiary from massive investments in artificial intelligence as AI workloads require instant access to datasets from high bandwidth flash memory located next to the GPUs in an AI server. Looking ahead, we believe the transition to AI inferencing, which requires instant data availability, will require substantially more NAND flash memory. This structural transition from a highly cyclical business to a more predictable demand environment, combined with sustainable margin improvements, could lead to valuation multiple expansion."
