SanDisk Corp. (SNDK) experienced a significant pre-market surge of 5.05%, driven by a wave of positive analyst actions and a broader recovery in the storage and semiconductor sector.

The rally follows multiple price target upgrades from major financial institutions. Analysts at Mizuho raised their target to $2,200 from $1,825, while BofA increased its target to $2,100 from $1,550. Cantor Fitzgerald also issued a substantial upgrade, adjusting its price target to $2,900 from $1,800. These moves reflect growing confidence in the company's prospects amid strong demand for memory chips.

Furthermore, the stock is rebounding as part of a sector-wide recovery from an oversold condition. The storage sector had faced a sharp selloff earlier in the week after Broadcom provided AI chip revenue guidance that fell short of market expectations. Wall Street analysts have since characterized that selloff as an overreaction. Positive sentiment was also bolstered by comments from Nvidia's CEO, who expressed strong confidence in sustained AI hardware demand, predicting a "multi-year silicon drought."
