Sandisk Corporation (NASDAQ:SNDK) stock advanced on Thursday as a global technical rebound and sector-wide stabilization lifted the semiconductor industry.

The upward move follows a multi-day sell-off that prompted investors to actively buy the dip. Nasdaq futures are up 0.53% while S&P 500 futures have gained 0.13%.

The massive semiconductor rout earlier in the week—triggered by profit-taking after Samsung Electronics Co. reported second-quarter earnings—eased as Asian chip benchmarks like South Korea’s KOSPI rebounded, prompting a parallel recovery in U.S. data-storage equities.

Short Interest Data Signals Pressure

Short interest in Sandisk increased during the last reporting period, rising from 9.21 million shares to 10.91 million shares. This increase places 11.56% of the company’s publicly available shares short. Based on the recent average volume of 11.01 million shares traded per day, short sellers would require approximately one day to close out their positions without driving the stock price sharply higher.

Analysts Note Industry Valuations

The rebound follows commentary from Gerber Kawasaki CEO Ross Gerber on Tuesday, who stated on X that investors selling semiconductor stocks were “captured by very short term thinking.” Gerber labeled semiconductor companies “some of the least expensive stocks in the market” and described the recent weakness as “a gift.”

Citi Warns Of Competitive Headwinds

The sector stabilization comes amid long-term competitive risks highlighted in a Wednesday Citi Wealth CIO Weekly Bulletin.

Citi noted that domestic memory chips from China are “gaining international recognition,” presenting a potential global pricing pressure risk for incumbent vendors like Micron Technology Inc. (NASDAQ:MU), Sandisk and Western Digital Corp. (NASDAQ:WDC).

Citi warned that this emerging validation could create a persistent “margin overhang” narrative, capping upside contract pricing for DRAM and NAND in commoditized segments.

Critical SNDK Levels To Watch After Recent Pullback

From a trend perspective, SNDK is still in a strong longer-term uptrend: it’s trading about 51% above its 100-day SMA ($1185.04) and roughly 146% above its 200-day SMA ($727.38).

At the same time, it’s trading 8.6% below its 20-day SMA ($1958.12), which frames the current setup as a pullback inside a broader bullish structure rather than a clean breakout attempt.

Momentum is best explained by RSI, which sits at 47.19—neutral and consistent with a stock that has worked off prior overbought conditions and is trying to stabilize.
