SanDisk Falls to $1,708 as Morningstar's AI Warning Deepens the Memory Rout

What Morningstar Actually Said

The single catalyst that turned Thursday's memory weakness into a broad de-rate came from a Bloomberg TV segment. Morningstar director of research Lorraine Tan warned that a large slice of AI names could give back 20% to 30% before becoming buyable again, and singled out memory as the most exposed corner of the trade.

Her thesis is about pricing power, not demand collapse. Tan argued that supply additions from Samsung and SK Hynix will let supply catch up to demand, so 'you will not see the same loftiness in growth rate on the pricing of memory chips.' She paired that with doubt on the market's assumption that AI spending keeps compounding through 2028, calling the second-quarter returns 'a bit scary' precisely because the tape is extrapolating them forward. When a stock is priced for perfection after an 800%-plus run, that is all it takes.

Why Memory Is the Fault Line

This was a group move, which is the tell that it is macro positioning rather than a SanDisk-specific problem. On the session, SanDisk fell about 11% to $1,802 in the equity, Seagate dropped 7% to $852, Western Digital 7% to $556, and Micron 4% to $992, with the Roundhill Memory ETF off 5% to $62. Overnight the same names extended the slide as the memory pump faded.

Underneath the valuation call sits a real demand question. With most output from the top manufacturers routed straight to AI infrastructure, memory price hikes are now bleeding into finished goods — a dynamic that sharpened after Apple and Microsoft raised prices and traders started asking whether higher costs dent end demand. If Samsung, SK Hynix and Micron all bring capacity online around the same window, the shortage that drove this year's margin expansion can flip to glut faster than the bulls model.

The Bull Case Is Still Raising Targets

What makes this a positioning reset rather than a fundamental break is that the sell side is lifting targets into the drawdown, not cutting them. Bank of America raised its SanDisk target to $2,500 from $2,100 with a Buy, arguing the NAND supply-and-demand imbalance and firm pricing hold through 2027, and Bernstein is carrying a $3,000 target on the name even as it plummets.

That gap — a stock down double digits on the day while its highest targets sit 45%-plus above spot — is the classic signature of a crowded winner being trimmed at the start of the second half, not a change in the earnings story. The risk cuts both ways: the same parabolic run and thin liquidity that let SanDisk shed 17.53% in seven hours can produce equally violent snapbacks on any sign the supply-glut fear was priced too aggressively.

How the Perp Is Trading

The HIP-3 SNDK perp sits near $1,708, down 17.53% over the trailing seven hours — a deeper cut than the roughly 11% intraday equity move, because the rolling window catches the tail of the prior session's slide and because the perp's thinner book amplifies directional flow. Volume is not thin, though: the market has turned over about $353.9M in the last 24 hours, so this is a well-traded venue absorbing real two-way interest, not a low-liquidity air pocket. It is also the latest leg of a multi-session unwind on the name, following the memory rout that dragged the perp toward $1,772 earlier in the day.
