SanDisk Rebounds 4.3% After-Hours on Morgan Stanley’s $1,100 Target Hike

Rebound in Extended Trading

SanDisk (SNDK) emerged as a primary focus for traders in Tuesday's after-hours session, climbing 4.35% on high volume of 14.1 million shares. This move represents a 4.22% outperformance relative to the S&P 500, which remained unchanged after the bell. The surge in extended trading effectively reverses a period of intraday volatility, as institutional buyers appeared to step in following an aggressive analyst upgrade that highlights the company's central role in the AI infrastructure build-out.

The Morgan Stanley Catalyst

The catalyst for the after-hours strength is a major price target revision from Morgan Stanley. Analyst Joseph Moore raised his forecast for SanDisk to $1,100 from $690, maintaining an Overweight rating. The firm’s "reset" is based on a projected 90% increase in NAND average selling prices (ASPs) during the first half of 2026, driven by a structural supply-demand imbalance.

"Hyperscalers are pulling enormous volumes of NAND flash into enterprise SSDs for training, inference, and vector storage," Moore noted in the report. Morgan Stanley now models SanDisk's 2026 earnings per share at $127.92, nearly 42% above the current Wall Street consensus. This bullish outlook has shifted investor sentiment, turning the focus toward the company's ability to maintain high margins during this pricing supercycle.

Earnings Anticipation and Sector Context

The after-hours move also serves as a "buy the dip" signal ahead of SanDisk’s fiscal third-quarter earnings, scheduled for release after the close on Thursday, April 30. The company has established a formidable track record of outperforming expectations, including a massive 75% earnings surprise in the previous quarter. Analysts at Zacks Investment Research currently maintain a "Strong Buy" rating on the stock, citing a positive Earnings ESP of +4.96%, which often precedes an upside surprise.

SanDisk’s performance is increasingly viewed as a pure-play barometer for AI storage demand. While the broader technology sector faced headwinds during the regular session, SanDisk’s after-hours decoupling underscores the specific strength of the data center storage market. Revenue from the data center segment has exploded over the past year, growing from just 1% of total sales to approximately 15%, as AI-optimized SSDs become a critical bottleneck for GPU-heavy workloads.

Forward Outlook

As the market looks toward Thursday's report, the key metrics will be SanDisk's guidance for the remainder of 2026 and the progress of its next-generation BiCS8 flash technology. With the stock trading near 52-week highs and exhibiting high beta, the 4.35% after-hours gain suggests that the "storage supercycle" narrative remains the dominant force for investors. If the company can validate Morgan Stanley’s aggressive pricing forecasts, the current rally may have significant further runway.
