The Columbia Seligman Global Technology Fund reported that it missed the significant rally in Sandisk Corporation (SNDK) during the second quarter of 2026, which detracted from its relative performance. Sandisk shares surged by 2,266.94% over the past 52 weeks, driven by a massive increase in demand for high-bandwidth memory to support AI workloads. The fund's Institutional Class shares returned 50.34% in Q2 2026, outperforming the MSCI World Information Technology Index's 33.65% gain, primarily due to strong stock selection in semiconductors and technology hardware.
