SNDK arrives at its April 29 earnings report having more than doubled off its lows, with short sellers caught offside and the Street scrambling to revise higher — the question now is whether the fundamentals have caught up with the tape.
The price action alone sets a charged backdrop. The stock added 8% on Monday and is up 17% on the week, extending a 74% one-month rally that has pushed shares to $1,070. Options positioning has edged more defensive into the print — the put/call ratio is running at 1.03, modestly above its 20-day average of 0.99, though at just 0.6 standard deviations above the mean, the tone is cautious rather than alarmed. The RSI at 68 confirms momentum is elevated but not yet technically stretched. What is notable is the sharp tick up in short interest: estimated SI jumped 14% in a single session on April 24 to reach 6.3% of free float — suggesting some traders are actively fading the run rather than chasing it.
Borrow conditions, however, remain remarkably easy for a stock that has tripled in a year. Cost to borrow is just 0.35% APR, and utilization has fallen back to under 1% — well below the 52-week high of 12.9%. That gap signals ample capacity to build short positions further, but also means there is no structural squeeze fuel sitting in the lending market. Closest peer WDC — which holds a ~5% stake in SNDK — rose 8.5% on the week but carries a much heavier short burden with days-to-cover at 4.3x versus SNDK's 0.3x. The contrast underlines how differently the market has priced the two NAND storage names through the same cycle.
The bull case rests on SanDisk's pivot toward high-capacity data center NAND. Average selling prices and gross margins are improving as the company prioritises that mix. EPS momentum ranks in the 95th percentile on a 30-day basis and at the 100th percentile on a 90-day view — the estimate revision trend has been one of the most powerful in the universe. Analysts have followed accordingly: BofA lifted its target to $1,080 last week while maintaining Buy, Evercore ISI initiated at Outperform with a $1,200 target in mid-April, and the consensus mean has moved to $968 — now roughly 10% below current levels after the stock ran through most targets. The bears counter with real structural risks: concentrated supplier dependency, ongoing IP litigation exposure, and the inherent cyclicality of NAND pricing, which has been unusually supportive but may not stay that way. The EV/EBITDA multiple at 12x has compressed 2.2 turns over the past month even as the stock surged, reflecting earnings upgrades running ahead of the price — but the analyst return potential has now flipped slightly negative at -6%, the first time the consensus has been underwater in the recent rally.
Insiders have been consistent sellers throughout the move — the CTO sold $2M in shares at $913 on April 20, and the CEO sold roughly $1M in late February near $632. Net insider selling over 90 days totals approximately $8.8M. The pattern is one of systematic liquidation as the stock rerated, not panic — but it adds weight to the bear argument that those closest to the business have been happy to trim on strength.
The April 29 print is therefore less about whether the NAND upcycle is real and more about whether margin delivery and forward guidance can justify a stock that has already priced in a great deal of the recovery.
