Memory stocks fell hard this week, from Micron (MU) to Western Digital (WDC). Sandisk (SNDK) lost 29%, and Goldman's price target says it should be 60% higher.
Sandisk (SNDK) fell 29% this week, the worst of a brutal stretch for memory stocks that also hit Micron (MU) and Western Digital (WDC). Two weeks ago Goldman Sachs raised its SNDK target to $2,200, more than 60% above Friday's close. Earnings on August 5 start settling the argument.

SK Hynix (SKHY) and Samsung make almost 80% of the world's AI memory. That's why Micron (MU) and US chip stocks crashed again (July 16, 2026)
Chip stocks fell hard again on July 16: SK Hynix's US shares (SKHY) closed down 13.7%, SanDisk (SNDK) 12.6%, Western Digital (WDC) 9.2%, Micron (MU) 5.7%, even after TSMC's record quarter. The reason traces back to Korea, where Samsung and SK Hynix make close to 80% of the world's AI memory, and to China's CXMT pricing an $85.7 billion IPO the same day.

TSMC beat earnings for a seventh straight quarter. The whole chip sector sold off anyway, and health care picked up the money.
TSMC beat Q2 earnings for a seventh straight quarter and raised its own 2026 capex forecast, an unusually bullish print. The semiconductor sector sold off anyway, continuing this week's memory-chip unwind, while health care, led by big earnings beats from UnitedHealth and Abbott, picked up the money instead.

SpaceX briefly fell below its IPO price today, and the revenue never supported a $2 trillion valuation
SpaceX dipped as low as around $132 on Wednesday, briefly trading below its $135 IPO price for the first time, before closing at $135.27, just pennies above it. With about $18.7 billion in revenue last year, a $2 trillion valuation was always a stretch, and Morningstar said as much before the IPO even priced.

Money is rotating out of semiconductor stocks and into the Mag 7 today. (July 15, 2026)
The real move Wednesday is money rotating into the Mag 7, Apple, Microsoft, Amazon and Meta are each up more than 3%. That money is coming out of semiconductor stocks, as SK Hynix's Nasdaq ADR, Micron and SanDisk all give back this week's spike.

Inside the AI hardware stack, from Nvidia's chips to the grid that powers them
An AI data center is seven layers of hardware: GPUs, memory, storage, CPUs, networking, manufacturing, and power. Here's the full map, with the public companies behind each layer and where the bottlenecks actually are.

Jim Cramer's tech calls, like Micron and Intel, are missing far more than everything else
We pulled 23 of Jim Cramer's stock calls from late April through early July and checked the real numbers. His tech picks are down 7.2% on average with just 1 winner out of 10. His other calls are roughly flat, and just under half are green.

Chip stocks just had their best day in weeks. Meta and Amazon are both betting billions that AI compute demand isn't topping out (MU, WDC, META)
Micron, SanDisk, and Western Digital are having their best day in weeks. A week after a rumor said Meta had too much AI compute, Meta and Amazon both bet billions that demand is still growing, and Samsung's own record quarter couldn't shake investors until this week's data center news did.

Wall Street used to move the Kospi. This week, the Kospi moved Wall Street.
South Korea's Kospi tumbled into a bear market this week. Its relationship with Wall Street isn't a one-way street. It runs both directions, depending on where the shock starts.

Samsung's record beat couldn't stop a memory stock selloff, and Micron (MU) is caught in it
Samsung posted a record 89.4 trillion won ($58.5 billion) Q2 operating profit, up 18-fold year over year, and the stock still opened lower. Memory names like Micron, SanDisk, and Western Digital are down sharply while the broader Nasdaq 100 barely moved. This is still developing after-hours and can change fast.

It is not just the chips: optics, memory and the neo-clouds all sold off this morning
The whole AI build-out sold off Monday morning, not just semiconductors. Optical names like Coherent (COHR) led the drop, memory (MU) and the neo-clouds fell hard, and Nebius (NBIS) was the lone holdout. What is going on.

Samsung, SK Hynix and Micron (MU) are all trillion-dollar stocks now. Here is how they stack up against the Mag 7.
The AI memory boom turned Samsung, SK Hynix and Micron (MU) into trillion-dollar companies. Here is how the memory giants stack up against each other and the Mag 7, and the DRAM ETF that packages them in one ticker.

The AI shortage keeps moving: from GPUs to memory, and now to hard drives (STX, WDC)
The AI shortage keeps rotating down the supply chain: first GPUs, then compute and networking, now memory, and hard drives are the leg lighting up next. The pattern, the stock moves at each stage, and what could be next.

Korea's market halted for the third time this week. Micron (MU) fell overnight, then bounced at the open.
South Korea halted trading a third time this week as SK Hynix and Samsung fell about 9 percent. Micron (MU) dropped overnight, then bounced at the open. Why this memory selloff is about leverage and positioning, not demand.
