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.
We built a stock score tool. It gave Intel a D, and I bought the stock anyway.
One pick in every layer of the AI hardware stack, each one graded by the SEC-filings scoring tool we just built. Four picks agree with the tool: NVDA, WDC, TSM, VRT. Micron is a partial. INTC and COHR do not agree with the tool at all, and I am holding both anyway.
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.
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.
What is HBM? The memory chips powering the AI boom
Only three companies make high bandwidth memory, the chips every AI accelerator depends on, and supply is sold out through 2026. What HBM is, who makes it, and how to invest in it.
Astera Labs (ALAB) rallies again, and Wall Street's targets can't keep up
ALAB surged again as chip stocks rallied broadly on July 6, extending a two-week run built on a Q1 beat and Nasdaq-100 inclusion. Even Bank of America's Street-high $450 target, set nearly two weeks ago, can't keep pace with the stock.
Hyperliquid's Sunday tape shows chip and memory stocks bouncing hard
Western Digital, SanDisk and Micron are all up more than 6% from Thursday's close on Hyperliquid's 24/7 stock perpetuals. Here is the Sunday snapshot, and why it is not the same as Sunday night's real reopen.
Micron (MU), Nebius (NBIS) and chip stocks jump on Hyperliquid's weekend tape
Real markets are closed for July 4th, but tech and chip stocks are trading green right now on Hyperliquid's 24/7 stock perpetuals. Micron, Marvell and Nebius lead the bounce, and the S&P 500 and Nasdaq perpetuals are up too. Here is the full read, and why Monday could look nothing like this.
Chips had their third worst day of 2026 and the S&P barely noticed (MU, INTC)
The S&P 500 closed within a whisker of flat on July 1 and the chip trade still had its third worst day of the year. Micron fell 10.5 percent, Intel lost 9 percent, and Meta gained almost 9 percent on the other side. Here is the damage report.
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.
Sandisk (SNDK) ripped more than 20% on Micron's (MU) blowout: the memory stocks to watch
Sandisk (SNDK) jumped more than 20% today, the loudest name in a memory-stock rally lit by Micron's (MU) record quarter. Why SNDK ripped, and the other memory names riding the same wave.
