SanDisk Corp. (SNDK) shares experienced a significant pre-market plunge on Thursday, dropping 6.01% as the storage sector faced widespread pressure. The decline comes amid a mixed trading session for tech stocks, with some companies seeing gains while others, particularly in the storage segment, faced setbacks.

The pullback in storage shares appears to be affecting multiple companies in the sector. Along with SanDisk's 6% drop, other notable declines include Western Digital and Seagate, both down 4%, and Micron Technology, which saw a 3% decrease. This sector-wide movement suggests broader market forces or industry-specific concerns may be influencing investor sentiment towards storage companies.

Interestingly, the tech sector as a whole showed mixed performance. While storage companies faced headwinds, networking giant Cisco Systems saw its shares rise 7% in pre-market trading following raised full-year forecasts for profit and revenue. This disparity highlights the varying fortunes within the technology industry, with companies exposed to artificial intelligence and networking seeing more positive momentum compared to those in the storage segment.
