SanDisk Corp. (SNDK) experienced a significant pre-market plunge of 6.52% on Thursday, as the stock moved sharply lower ahead of the regular trading session.

The decline in SanDisk's share price is attributed to broad weakness across the technology and semiconductor sectors. According to market reports, major tech stocks were falling in premarket trading, with semiconductor companies particularly affected. SanDisk was specifically mentioned among chip stocks that dropped, with Marvell Technology also falling 6% in pre-market activity.

Further context indicates that memory chip stocks were under pressure, with the broader semiconductor sector showing significant declines. This sector-wide weakness contributed to SanDisk's substantial pre-market drop, as investors reacted to negative sentiment in the technology hardware and semiconductor space.
