SanDisk’s shares have been on a breathtaking run, but the rally is showing signs of strain. After hitting a fresh all-time high of $2,167.33 on Monday, the stock suffered a sharp reversal on Tuesday, shedding over 5%. A modest recovery on Thursday brought the price back to $2,110.45, a gain of roughly 8% for the session, yet the broader picture remains one of extreme volatility and caution.
The pullback was partly driven by the Federal Reserve’s rate decision on Wednesday, which hit highly volatile stocks particularly hard. With a beta of 3.45, SanDisk is among the most interest-rate-sensitive names in the market — every shift in monetary policy amplifies moves more than threefold. The shares tumbled to $1,958.80 before regaining some ground. Even after that dip, the stock is still up over 610% from its year-end closing level.
Technical indicators are screaming overheated. The relative strength index briefly spiked above 99 earlier this week — a near-unprecedented level. After the recovery, the RSI has settled at 69.1, still firmly in overbought territory. The annualized 30-day volatility stands at a staggering 98%, underscoring a market that is anything but orderly. The stock now trades at nearly double its 100-day moving average of $1,017, a stretch that historically has been followed by consolidation or sharper corrections.
Yet the fundamental narrative continues to intensify. A potential game-changer is emerging in the form of SpaceX. According to analysts at Lynx Equity, Elon Musk’s rocket company — fresh off its massive IPO — is planning a major expansion of its AI infrastructure. SanDisk is seen as the preferred supplier for high-performance SSDs and NAND flash memory. If those orders materialize, SpaceX could become a “super-client,” with demand far exceeding typical cyclical patterns.
Should investors sell immediately? Or is it worth buying SANDISK?
The structural supply dynamics also support a bullish long-term view. Bank of America recently lifted its price target on SanDisk to $2,100, citing a structural shortage of NAND flash that could persist for several years. SanDisk’s vertical integration — particularly through its Japanese joint venture — gives it a production edge while rivals struggle with capacity constraints. A significant portion of the company’s output is already contracted out to 2027, locking in revenue visibility that hyperscale customers crave.
Despite the record highs and the sizzling pace of gains — 22% in the past week and more than 54% over the last month — caution is creeping in. The market capitalization has swollen to roughly $317 billion, a multiple of SanDisk’s historical valuation that feels stretched even by AI-boom standards. The RSI reading of 69.1, down from the extreme spike above 99, still suggests residual overheating. Polymarket labeled the stock “the most overbought in history,” a label that can weigh on sentiment even when fundamentals are strong.
Investors are now weighing whether the SpaceX catalyst and the enduring NAND shortage can sustain the current valuation — or whether the stock needs a breather. The upcoming share exchange agreements in June will provide a key test. They will reveal whether the rally can consolidate or whether a deeper correction is in store. Without fresh catalysts, the overheated equity may struggle to hold its gains.
SanDisk’s dramatic ascent from a 52-week low of $146 in October 2025 has turned early buyers into ten-baggers in just eight months. But the question hanging over the market is no longer about the quality of the business — it is about how much of that quality is already priced in. The arrival of a super-client like SpaceX could tilt the equation back toward optimism, but for now, the stock is walking a tightrope between momentum and mean reversion.
