SanDisk (SNDK) Surges 14.57% in Six Days to 2025 High on Analyst Upgrades, Institutional Momentum

SanDisk (SNDK) climbed 5.02% in intraday trading on Wednesday, marking its sixth consecutive day of gains. The stock surged 14.57% over the past six sessions, reaching its highest level since August 2025 with an intraday high of $50.76, reflecting renewed institutional confidence and momentum-driven buying.

The rally aligns with a 7-point upgrade in SanDisk’s IBD Relative Strength Rating to 71, a proprietary metric highlighting its outperformance against peers. This improvement signals stronger relative momentum, attracting investors seeking market leaders amid a competitive tech sector. Analyst activity further amplified optimism, with Cantor Fitzgerald and Goldman Sachs both reiterating Buy ratings in recent weeks. Cantor Fitzgerald set a $50 price target (5.5% upside from its August 25 close), while Goldman Sachs projected $55 (18.7% upside), reflecting divergent but bullish assessments.

The analyst consensus remains tilted toward SanDisk, with an average price target of $57.45—21.3% above the $47.35 level as of August 25. This valuation gap underscores perceived undervaluation, particularly against the stock’s one-year high of $58.36. Despite volatility between $27.89 and $58.36 over the same period, the recent analyst upgrades and rating improvements have likely bolstered liquidity, with daily trading volume averaging 2.76 million shares. Increased institutional participation could reinforce upward price action as the stock approaches key resistance levels.

While macroeconomic context and earnings data remain absent from the provided materials, the focus on ratings upgrades and institutional buy signals suggests SanDisk’s market positioning is gaining traction. The absence of recent earnings reports limits assessment of fundamental drivers, but the sustained analyst optimism and relative strength metrics indicate momentum is being fueled by strategic business dynamics and sector positioning. Investors are likely to monitor near-term catalysts, including potential earnings surprises or product developments, as the stock tests its 2025 peak.
