Sandisk Corporation (SNDK) has been one of the market’s most spectacular performers, with the stock up over 4,000% in the past year and 505% year‑to‑date. On Tuesday it opened at $1,478.69, boasting a 12‑month range of $35.79 to $1,600.00. This extraordinary rally has been fuelled by a tidal wave of demand for its memory products—SSDs, memory cards, USB drives and embedded solutions—driven by the artificial intelligence boom and escalating data‑center investments from tech giants like Microsoft, Google and Amazon.
The earnings report for the March quarter shattered expectations. Sandisk delivered earnings per share of $23.41, obliterating the $14.17 consensus by over $9. Revenue surged 251% year‑over‑year to $5.95 billion, powered by a 233% jump in data‑center sales. Net margin stood at 34.19% and return on equity hit 44.06%. For the fourth fiscal quarter of 2026, management guided EPS in a range of $30.00–$33.00, and the full‑year analyst consensus has rocketed from $41.60 just two months ago to $63.58.
The blowout numbers triggered a flurry of bullish analyst actions. Wells Fargo lifted its target to $1,250, Mizuho set $1,220, Citigroup jumped to $2,025, and Melius Research published a Street‑high $2,350 target. Weiss Ratings upgraded the stock from Hold to Buy. Overall, there are 3 Strong Buy, 18 Buy and 4 Hold ratings, with an average target of $1,157.14. On the institutional side, however, Jefferies Financial Group slashed its stake by 41.3%, while several smaller firms added modestly. Insiders have also been net sellers, unloading approximately $6.55 million worth of shares in the past three months.
Despite the stellar fundamentals, a technical red flag has emerged. The daily chart shows a potential double‑top formation, with peaks near $1,597 and a neckline at $1,276—the low from May 18. This is a widely recognised bearish reversal pattern. The stock also remains stretched far above its 100‑day moving average of $838. A break below the $1,276 support could trigger a deeper pullback as investors lock in profits. Conversely, a decisive move above $1,597 would invalidate the pattern and could open the door to $1,700.
With guidance signalling further acceleration—full‑year revenue seen at $19.54 billion and next‑year EPS at $175—the bull case is compelling. Nevertheless, the combination of extreme valuation, insider selling and a classic technical warning suggests that caution is warranted. Whether Sandisk can push through resistance and justify the most aggressive targets remains an open question.
