SanDisk Crashed 48% While Sales Grew 370%. I Think the Market Blinked

Updated August 14: the stock is up about a third, and the reason was in the August 5 call

SanDisk closed August 13 at $1,528.11, up 13.67% after its 2026 Investor Day, and traded near $1,626 in Friday morning's session, up a further 6.4% or so. Against the $1,223.74 this piece called a buy on August 10, that is roughly +33% in four sessions. The record close of $2,335 from June 25 is still about 30% away.

The catalyst was not the shortage thesis this piece argued. It was contract structure. SanDisk has signed long-term agreements with eight datacenter and edge customers carrying a minimum of $93.9 billion of revenue at floor pricing, with fixed near-term prices and collars later, backed by $16.5 billion of customer deposits and financial guarantees. Remaining performance obligations were $59.8 billion at quarter end and $91.1 billion including two deals signed after it. CFO Luis Visoso disclosed all of it on the August 5 earnings call, eight sessions before the market paid for it.

That changes the exit trigger stated below. This piece said to watch for the first quarter where pricing rolls while the guide stays optimistic. Roughly two-thirds of fiscal 2028 bits now sit under a price floor, so the spot roll that would once have hit the whole book will hit under half of it. I still want the Micron confirmation, and I would now weight it less.

The bear case that survives is the ceiling. The same collars cap the upside on that contracted volume if NAND stays tight into 2028. JPMorgan's Harlan Sur moved to Overweight from Not Rated on August 14 with a December 2027 target of $2,250, about 47% above the Thursday close, which is a sell-side number rather than this site's. Full breakdown: the 80% margin is the floor case.

TL;DR

• Yes, for a thesis holder with the stomach for 40% swings. This is not a stock, it is a commodity cycle wearing a ticker.
• SNDK trades near $1,223.74, roughly 48% below the June 25 record close of $2,335, and still up more than 490% in 2026.
• The fundamentals did not travel with the drawdown: sales rose more than 370% year over year to $9.0 billion, guidance implies more than 350% growth ahead, and Samsung says the memory shortage runs into 2028.
• The practical catch most coverage skips: at $1,223 a share, one options contract is about $122,000 of notional, which removes the income strategies from most accounts entirely.

Is SanDisk a Buy After the Rollercoaster?

Yes, on one condition: the position has to be built for the asset's actual behaviour, which this year has included a run to $1,900, a crash, a recovery and now a 48% drawdown from the June record, all while the underlying business only got stronger. Anyone who cannot watch a holding halve without selling it should not hold this one, because it has halved during a supercycle.

The case rests on physical supply, not sentiment. AI servers consume NAND at rates the industry did not build for, pricing has gone vertical, and SanDisk's revenue, up 370% to $9 billion with guidance implying 350% more, is what a genuine shortage does to a commodity producer's income statement. The supercycle thesis has been tested on this site before and the physical argument keeps winning: capacity takes years to add, and 2028 is Samsung's own estimate for relief.

What the 48% drawdown priced is the memory of every previous cycle: these stocks top before the shortage ends, violently and without notice. That fear is legitimate. It is also, at half the June price with the guide still climbing, increasingly paid for.

The $122,000 Problem

A constraint worth naming because it changes what "owning SNDK" means. With the shares at $1,223, a single options contract controls about $122,000 of stock. Fractional options do not exist, so covered calls and cash-secured puts, the standard ways to get paid for holding a volatile name, are structurally unavailable to most retail accounts. The choice is shares or nothing, which makes the sizing discipline the entire risk management: whatever the number of shares, it has to be one whose 40% swing changes nothing about the holder's month.

My structure: a starter here at $1,223, adding only on evidence, either NAND contract pricing extending into 2027 or the next report holding the guide. The exit trigger is equally specific, because commodity cycles do not send memos: the first quarter where pricing rolls while the guide stays optimistic is the top talking, and Micron will usually confirm it first.

The One-Line Read

SanDisk at $1,223 is the shortage at half price: a business growing 370% into a supply gap its biggest competitor dates to 2028, discounted 48% because everyone remembers how memory cycles end, and the call is yes at a size that treats a 40% swing as weather, because with this ticker, it is.
