SNDK closed June at $2,273.73 — a 15.8% weekly gain and a new post-peak high — yet short sellers have not blinked, leaving the stock caught between a wall of analyst upgrades and a short base that keeps rebuilding.
The positioning picture is a study in contradictions. Short interest climbed 12.7% over the week to 7.1% of free float, roughly 10.5 million shares, matching the levels bears held when the stock was at its prior all-time high. That rebuilding is notable: as recently as late May, SI was above 11.3 million shares, then fell sharply, and has now clawed back. Bears are re-engaging at higher prices. Yet the borrow market tells a completely different story — availability is running at over 4,100%, meaning there are more than 41 shares available to borrow for every one currently shorted. Cost to borrow is a near-trivial 0.22%, up sharply on the week in percentage terms but still historically low in absolute terms. This is not a structurally stressed borrow — it is a well-supplied, easy trade. Options are similarly calm. The put/call ratio at 1.51 sits almost exactly in line with its 20-day average of 1.50, a z-score of just 0.19. The persistent defensiveness that characterised the rally through June has not intensified; options traders are hedging, but no more than usual.
The Street, however, is running hard in the opposite direction from the shorts. B of A Securities lifted its target to $2,500 on July 1, one day after Bernstein made the most aggressive move of the cycle — raising to $3,000 from $1,700 and naming SNDK a potential "biggest AI memory winner" over . Citigroup was already at $2,500. Every recent change has been a raise, with no downgrades in the visible window. The consensus mean of $1,864 now sits well below the current price, but as noted in the prior report, that gap reflects stale inputs from analysts yet to update rather than a deteriorating thesis. The bull case rests on tight NAND flash supply and surging enterprise SSD demand driven by AI workloads. The bear case centres on flash market cyclicality, supplier concentration, and the risk of losing hyperscaler qualification. Factor scores back the bulls on momentum: EPS momentum over 90 days ranks in the 98th percentile, and the 30-day reading is in the 93rd. The short score sits at 38.6 — a middling read that reflects the 7.1% SI level but is tempered by loose borrow conditions.
Insider activity introduces a mild drag on the narrative. Net selling over the past 90 days totals roughly $24 million across the CEO, CFO, CTO, and Chief Legal Officer. The CEO sold 1,569 shares at $1,479 in late May; the CFO sold at similar levels. The CTO followed with multiple tranches in June, the most recent at $2,185. None of these sales are enormous relative to total compensation structures, and significance scores are low, but the directional message is consistent — executives have been lightening into the rally rather than adding.
Peer performance this week cuts against the SNDK story. WDC fell 4.8% on the week and STX dropped 7.1%, while SNDK gained 15.8%. The divergence underscores that this move is being driven by SNDK-specific analyst catalysts rather than broad storage sector flows.
The August 14 earnings date is now the next hard reset. The two most recent prints delivered 1-day moves of +11.5% and +9.4%, with 5-day moves of +25.9% and +40.7% — a history of explosive post-earnings reactions that gives both bulls and bears reason to stay positioned. Whether short sellers sustain their 7.1% base into that print, or whether the continuing analyst target upgrades eat further into the overhang between now and then, is the tension worth tracking.
