Micron (MU) CEO sold $37.3 million in stock, the same 40,000 shares he has sold every 28 days since May

SK Hynix (SKHY) reported a record quarter and still missed. One analyst broke from the pack and called it within a quarter of a percent
SK Hynix reported 60.5426 trillion won ($41.6 billion USD) of operating profit against a 64.09 trillion won consensus, 5.5% short, on revenue 5.6% short. Both figures are records. The operating margin came in at 76%, right where the street had it, so the entire miss was revenue rather than profitability. Korea Investment & Securities was the only firm below the pack and landed within a quarter of a percent.
Kioxia hit limit-down again and is down 60% from its June peak. Sandisk (SNDK) co-owns its factories (July 28, 2026)
Kioxia closed at its limit-down price of 44,550 yen ($272 USD), down 18.33%, after finishing at the bottom of its daily band on July 17 as well. It is 60.5% below the 112,700 yen peak it set on June 22. It shares the Yokkaichi and Kitakami NAND plants with Sandisk (SNDK), which is why the two keep falling together.
Citadel says the Fed hikes Wednesday. All 104 economists Reuters asked say it won't (MU, NVDA, July 28, 2026)
I was sure Citadel's rate call knocked the Nasdaq down 2% Tuesday morning. Nvidia (NVDA) was green while Micron (MU) fell 7.69% and the 2-year yield never moved, so it was not the Fed at all. It was Seoul. Here is the split that actually matters at 2 p.m. Wednesday.
Michael Burry posted three charts making the AI bear case. Two of them show the selling already happened.
Burry shared three Bloomberg charts on the AI trade. One maps the circular deals around Nvidia (NVDA). The other two show big tech forward multiples back at or below their 10-year averages, with Apple (AAPL) the lone expensive name and the only megacap missing from the circular map.

I let Claude AI trade $100 on Robinhood, week 6: It swapped CleanSpark (CLSK) for D-Wave Quantum (QBTS) and quit 23 minutes later
Claude AI's CleanSpark (CLSK) stop fired Monday for a $2.36 loss and was right, since CLSK fell another 10% after. Then it bought D-Wave (QBTS) at Tuesday's open into a chip crash, sold 23 minutes later for $1.80, and filed a report two minutes after that saying it had not traded.

Scott Allen sold 879 Micron shares for $879,000 at exactly $1,000 each on July 23, the only unscheduled large insider sale our tracker caught last week. His other 34,958 shares stayed put.
About $25 billion of Microsoft's (MSFT) AI budget is memory getting more expensive. Wednesday says whether that grew.
Microsoft told investors in April it would spend about $190 billion on capital projects this year. Around $25 billion of that increase bought nothing new, it was the same buildout at a higher price after memory costs rose. Microsoft reports Wednesday after the close, two hours after the Fed decision.
Michael Burry's picks: the Micron (MU) bet is up 17%. He has been averaging down on Lululemon (LULU) since 2025.
Burry deregistered Scion, so the 13F trail stopped and his trades now surface first on a newsletter with 300,000 subscribers. Here is everything he has disclosed since June, priced as of July 27. The point of laying them out together is that he is not always right.

ChangXin Memory (CXMT) closed its Shanghai debut up 465.82%, passing ICBC as China's most valuable listed company and drawing level with Intel. Only 6.73% of its stock was tradable. The order book behind it is the part that matters for Micron (MU) and SK Hynix (SKHY).

US Central Command has gone two straight nights without striking Iran, and a Defense Department source told CNN operations are on a hold. Polymarket puts an effective ceasefire at 75% by August 31. US markets were shut all weekend, but the tokenized stock market never closed, and it spent Sunday buying the AI trade and selling oil.
If I had $1,000 for one AI chip stock, I'd buy SK Hynix (SKHY) over Nvidia (NVDA), Micron (MU) and AMD
Nvidia and SK Group signed a $500 billion AI infrastructure deal late Friday night, after both New York and Seoul had closed for the week. Given $1,000 for one of the four AI chip stocks, I'd put it in SK Hynix, which trades at 5.6 times forward earnings even after its 28% ADR premium against 6.4 for Micron.
Samsung just signed a $200 billion deal with Broadcom (AVGO), a 32-year TSMC (TSM) customer.
Samsung Electronics signed a memorandum with Broadcom on July 24 covering more than $200 billion of work over five years, through 2030. Broadcom has had TSMC make its chips since 1994, and about 95% of the wafers it outsourced last year came from there. Samsung's foundry holds 6.5% of the world market against TSMC's 72%, and Seoul had closed for the week before any of it was announced.

SK Group then committed 2,100 trillion won ($1.44T USD) to chip capacity and 15 gigawatts of AI data centers, built on Nvidia's Vera Rubin reference design. Nvidia put $1 billion into Naver on July 24. Here is what each side actually committed, and what is funded versus announced.

Tesla (TSLA) and Alphabet (GOOGL) are falling hard. The rest of the AI trade isn't (July 23, 2026)
Tesla and Alphabet kept falling through Thursday morning even as chipmakers, neoclouds and photonics stocks held up fine. Oil topped $100 a barrel after Trump threatened to bomb Iranian infrastructure over any new attack on shipping.
Alphabet (GOOGL) raised AI capex to $205 billion, its third hike this year. Nvidia (NVDA) and Broadcom (AVGO) barely moved after hours
Alphabet raised its 2026 capex guidance to $195-205 billion during Wednesday's call, its third increase this year, and GOOGL fell as much as 5% in extended trading.
