Sandisk Stock: Buy Before Aug. 5 Earnings?

Jul 21, 2026
Equipo Quant de Bobby

💡 Puntos Clave

Sandisk's explosive growth is tied to AI memory demand, but a high P/E and market jitters make it a risky bet despite likely earnings beat.

What Happened: Sandisk's Meteoric Rise and Upcoming Earnings

Sandisk (SNDK) has been one of the most explosive stocks of 2025, surging 3,810% since its spinoff from Western Digital in February. The company, a key supplier of NAND flash memory, has benefited enormously from AI-driven demand for data storage.

Every earnings report so far has sent the stock higher, with the most recent quarter showing a 251% year-over-year revenue increase and a 78.4% gross margin. Management guided for Q4 revenue of about $8 billion (up from $1.9 billion last year) and an 80% gross margin.

However, the stock has pulled back 36% over the past month, trading near its pre-earnings level from May. This sets up a potential catalyst when Q4 results are released on Aug. 5.

The broader AI sector has been under pressure due to fears of overspending, which could weigh on Sandisk despite its strong fundamentals. The company also introduced long-term contracts to stabilize its business cycle.

Why It Matters: AI Memory Demand and Valuation Risks

Sandisk is one of the few producers of NAND flash memory, a critical component for AI inference and data storage. As AI models become more complex, demand for non-volatile memory is expected to grow, giving Sandisk pricing power and revenue visibility.

The company's financials are stellar: 251% revenue growth, 78.4% gross margin, and operating income soaring from $2 million to $1.1 billion. Q4 guidance implies 321% revenue growth year-over-year, suggesting momentum is accelerating.

However, the stock's valuation is stretched. The P/E ratio peaked at 80 and now sits at 47, still high for a memory company. If AI spending slows or competitors increase supply, Sandisk's growth could decelerate sharply.

Investors should watch for earnings beats and forward guidance. A strong report could push the stock higher, but any hint of weakness could trigger a sell-off given the recent pullback.

Bobby Insight

Sandisk is a buy before earnings, but keep position size small due to high valuation and sector risks.

The company's revenue and margin growth are exceptional, and the stock has historically rallied after earnings. However, the P/E of 47 leaves little room for error, and AI spending fears could cap upside. A modest position allows participation in potential gains while limiting downside.

If you hold SNDK, the upcoming earnings could provide a short-term boost, but consider taking some profits given the 36% pullback and high valuation. Investors with exposure to AI memory plays should watch for signs of demand softening, as Sandisk's growth is tied to NAND pricing. Diversifying into other AI infrastructure names like NVDA could reduce single-stock risk.
