SanDisk Corp. (SNDK) extended its share decline on Tuesday, dropping as much as 5.4% intraday before closing 2.99% lower. The selloff was driven by shifting dynamics in the NAND flash memory market rather than broader concerns over AI demand or data center regulation, leaving investors to weigh whether an upcoming 8-for-1 stock split can reverse the downward momentum.
Data from Counterpoint Research shows a clear reversal in SanDisk’s market positioning. A year ago, the company and Chinese manufacturer Yangtze Memory Technologies Corp. were tied for fifth place globally with 11% share each. Both gained ground through the first quarter of 2026, reaching 13% and 14% respectively, but SanDisk slipped back to 11% in the second quarter, erasing a full year of gains. Yangtze Memory held steady at 14%, while Micron Technology added two percentage points and SK Hynix gained one.
SanDisk’s planned 8-for-1 stock split, set to take effect on November 19, has emerged as a closely watched potential catalyst. Market participants broadly view stock splits as an indirect indicator of business strength, as they typically follow sustained, substantial share price appreciation and are rare among underperforming companies.
Research from Bank of America backs up that historical pattern. Between 1980 and 2023, stocks that announced splits returned an average of 25.4% in the 12 months following the announcement, compared with an 11.9% average gain for the S&P 500 over matching periods, meaning split stocks consistently outperformed the broader market.
SanDisk shares traded at $1,330 when the split was unveiled on October 29. Applying the historical average return would push the stock to $1,667 a year after the announcement, implying roughly 98% upside from its recent price of $885.
That history-based projection still trails Wall Street’s consensus outlook. Among 34 analysts covering the stock, the median price target stands at $2,100, representing about 150% upside from current levels. The most bullish projection reaches $3,600, implying a 328% gain.
SanDisk has been one of the biggest beneficiaries of the global memory chip supply shortage, with both revenue and share price surging dramatically. The stock has more than tripled so far this year, following a 559% rally in the prior year. Robust demand from AI infrastructure buildout has pushed NAND flash prices up 160% over the past two years, lifting SanDisk’s fiscal 2027 first-quarter revenue to $11 billion, up 378% year over year, with non-GAAP diluted earnings per share reaching $49.51, a 40-fold increase.
Demand visibility is reinforced by long-term supply agreements with at least eight customers, covering roughly two-thirds of SanDisk’s projected NAND flash output for fiscal 2028. The contracts include fixed purchase volumes, structured pricing terms and financial guarantees. Next year, the company will begin sampling high-bandwidth flash technology, which Goldman Sachs analysts estimate could cut AI inference costs by 30% and create a $40 billion to $150 billion market by 2030.
Still, concerns persist over the industry’s cyclical, commoditized nature. NAND flash pricing is driven primarily by supply and demand rather than differentiated technology, meaning SanDisk’s current pricing power stems from acute supply shortages, not a durable competitive advantage. Every major memory producer is ramping up production capacity, setting the stage for a potential supply glut that could drive prices sharply lower; during the last industry downturn, NAND prices fell 70%.
SanDisk trades at less than 7 times trailing earnings and below 4 times next year’s projected profit, placing it in low-multiple territory and splitting investor opinion. Some see the latest selloff as a short-term sentiment swing and a buying opportunity, while others caution that the next industry downturn could trigger a sharp earnings contraction. For investors comfortable with volatility, a small position may be warranted, while more conservative capital continues to favor market leaders with lasting competitive edges.
