Shares of Sandisk (SNDK) experienced an impressive 18% rally on Thursday, reaching $2,263.57, following memory chip competitor Micron (MU) delivering exceptional fiscal Q3 financial results that lifted both companies’ stock prices.
Micron reported adjusted earnings of $25.11 per share, significantly exceeding Wall Street’s consensus estimate of $20.78. The company’s quarterly revenue reached $41.5 billion, representing approximately a four-fold increase year-over-year and surpassing analyst projections of $35.8 billion.
While Sandisk won’t release its own quarterly figures until Aug. 24, the strong Micron results provided market participants with insight into current memory sector dynamics.
Wall Street analysts are projecting substantial performance from Sandisk’s forthcoming earnings release. Consensus estimates point to earnings of $33.72 per share, potentially exceeding the previous quarter’s results by more than 100%.
Micron’s GAAP earnings increased 104% quarter-over-quarter in its most recent period. Market participants appear optimistic that Sandisk, benefiting from two additional months of favorable memory pricing trends, could deliver comparable growth.
Artificial Intelligence Driving Supply Constraints
During Micron’s earnings conference call, CEO Sanjay Mehrotra emphasized that artificial intelligence-related demand continues at elevated levels, with the company making unprecedented capital investments to meet requirements. Despite these efforts, he indicated supply constraints will likely persist.
This supply-demand dynamic has been a key driver behind Sandisk’s remarkable performance. The company’s shares have appreciated 853% year-to-date and an extraordinary 4,670% over the past year, propelled by AI data center infrastructure spending and constrained memory availability.
Both Micron and Sandisk are securing extended supply agreements with customers at current favorable margin levels. Micron disclosed it’s achieving operating margins exceeding 80% on certain product lines. Sandisk is implementing comparable strategic initiatives, potentially insulating margins even if market conditions moderate.
Technical Analysis Suggests Overextension
The substantial price appreciation has attracted scrutiny from traders monitoring technical indicators. Prediction markets platform Polymarket recently characterized Sandisk as “officially the most overbought stock in history,” referencing its momentum characteristics.
The data supports these observations to some degree. Sandisk’s 14-month RSI registered 99.1 as of Wednesday, based on Dow Jones Market Data. Traditional technical analysis considers readings above 70 as overbought territory. For perspective, the stock’s record 14-day RSI of 95.32 occurred in September 2025.
Examining shorter timeframes, the 14-day RSI closed at 55.8 on Wednesday, falling within neutral range. However, the extended-term indicators present greater concern.
Sandisk currently trades 246% above its 200-day moving average, positioned near $652, and 51% above its 50-day moving average at $1,489.
The company has maintained public trading status for approximately 16 months following its Western Digital spinoff. During this period, shares have advanced from a $40 low to an all-time high of $2,354.39.
Sandisk’s current market capitalization totals $284 billion.
