Sandisk Corp. (NASDAQ:SNDK) stock surged up to 5% in Tuesday trading, triggering a wave of buy-the-dip activity. The rebound follows a Monday decline where volatility from South Korean chipmakers Samsung and SK Hynix dragged down the KOSPI and U.S. peers amid rising energy costs. The Nasdaq is up 0.74% while the S&P 500 has gained 0.13%, and Technology is adding 0.55%.

Market Momentum Reverses

Data from Goldman Sachs shared by investment strategist Mike Zaccardi on Tuesday, indicates that the S&P 500 momentum factor suffered one of its steepest three-week sell-offs on record. This unwinding reflects investors reallocating capital toward sectors with fresh catalysts. Benzinga Edge’s Momentum Rankings currently place Sandisk at the top of the market with a score of 99.96 out of 100.

On July 1, BofA analyst Wamsi Mohan reiterated a Buy rating on Sandisk and raised the price forecast from $2,100 to $2,500. Mohan stated, "We expect supply/demand imbalance in the NAND market to remain through 2027," noting that pricing should hold up through at least mid-2027.

Next-Generation NAND Sampling

The company also benefits from its July 2, announcement detailing the sampling of its BiCS10 1Tb TLC 3D NAND flash memory. Alper Ilkbahar, CTO at Sandisk, stated that the technology delivers “faster interface speeds, higher bit density and improved power efficiency for our customers.” The architecture improves bit density by 59% compared to the prior generation.

Geopolitical And Supply Risks

Though shares advanced Tuesday, Mohan highlighted downside risks for the memory sector. These factors include capacity acceleration from China’s Yangtze Memory Technologies Co. (YMTC), potential global oversupply, and market share shifts within enterprise solid-state drives (SSDs).
