Sandisk Corporation (SNDK) spent most of the past year rewarding investors who backed the artificial intelligence (AI) trade. Relentless optimism over booming memory demand kept the stock climbing until the rally suddenly lost its footing. On Monday, July 27, shares tumbled 11%, making Sandisk the worst-performing stock on the S&P 500 Index ($SPX).
The sell-off spilled over into the semiconductor sector, leaving other chip stocks under pressure too. Traders returned the next day with little appetite for bargains, driving another 14.25% intraday decline. The retreat revived a familiar debate among retail investors over whether Sandisk could hold above the psychological $1,000 mark.
