Microsoft (MSFT) is testing Moonshot's Kimi K3 for Copilot to cut its Azure AI bill by $600 million
Microsoft is testing Moonshot's Kimi K3 for Azure and Copilot, hoping to cut AI costs by $600 million, the same week the model's launch gave chip stocks a rough ride and its maker began prepping a $30 billion Hong Kong IPO.
Michael Burry cut his Oracle (ORCL) short in half, and says reports he closed it are fake news
Michael Burry sold half his Oracle (ORCL) puts on July 17 after a 63% stock plunge, then called reports that he'd fully exited the short "fake news." The same post added Nvidia (NVDA) puts, more DraftKings (DKNG), and a skeptical read on Netflix (NFLX).
I gave five AIs a pretend $10,000 to pick 5 tech stocks. Four bought Nvidia (NVDA). Claude went rogue.
ChatGPT, Gemini, Grok, Meta AI and Claude each picked five tech stocks to hold for six months. Four bought Nvidia. Claude went the other way. Every pick is here and the scoreboard runs monthly.
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.
Micron slid 6% into Friday's open, then flipped positive within the hour as chip stocks staged a violent rebound (July 17, 2026)
Chip stocks slid overnight and into Friday's open, with Micron down as much as 5.8 percent, then staged one of the sharpest reversals of the week within about an hour.
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.
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.
Should you actually copy stocks bought by hedge funds, Congress, or insiders? What the data really says
Copying stocks bought by Congress, hedge funds, and company insiders all sound like easy shortcuts. Here's what the actual research says happens once you try each one, and why the delay before you see the trade matters more than people think.
The Close, July 14: IBM lost a quarter of its value, and SK Hynix's Nasdaq stock jumped 27%
IBM lost about a quarter of its value in a single session after a weak preliminary report, and the damage spread across enterprise software. SK Hynix's brand-new Nasdaq stock went the other way, jumping 27% on a day chips broadly rallied.
Inflation fell for the first time since 2020, the Kospi closed green, and IBM still crashed 23% (July 14, 2026)
June CPI fell 0.4%, the first monthly decline since 2020, and chips bounced. Then IBM missed on preliminary results, lost roughly 23%, and dragged Workday, ServiceNow and Adobe down with it. CleanSpark jumped 8% on a $6.6 billion AI data center lease, and the Kospi closed green before the CPI number even existed.
Chips got smoked today. Tomorrow's CPI report at 8:30am decides what happens next.
Arm, Coherent, Micron, AMD and Nvidia fell between 3.5% and 7.5% Monday while Microsoft, Apple and Amazon finished green. The selling stayed inside crowded AI infrastructure names. Tuesday's 8:30am CPI report could send the same stocks sharply either way, and the real risk isn't even in the data yet.
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.
The Iran war just crashed the Kospi into its 7th circuit breaker of the year. SK Hynix fell harder than Samsung again.
South Korea's Kospi crashed 8.95% and halted trading for the seventh time this year as US strikes on Iran spread to Bahrain, Oman, Jordan and Kuwait. SK Hynix fell harder than Samsung again, and its three-day-old US ADR followed the Seoul selloff down too, though by a smaller margin.
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.
SK Hynix (SKHY) passed Samsung for one day in South Korea. My theory on why it ran to the Nasdaq
On June 22 SK Hynix passed Samsung as South Korea's most valuable company for the first time in 25 years. It lasted one day, and the Kospi hit circuit breakers the next session. Here's my theory on why that's exactly why SKHYV just sprinted to the Nasdaq.
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.
SK Hynix priced its Nasdaq debut 3.1% above Seoul, after demand ran 7 times oversubscribed.
SK Hynix guided its Nasdaq ADR offering to $149 each, a 3.1% premium to Seoul's close, after the book ran more than 7 times oversubscribed. Here's the math behind the premium and who anchored the deal.
A senator sold Apple and Nvidia in June. He bought Coherent and Micron instead.
Senator Sheldon Whitehouse's latest disclosure shows he sold Apple and Nvidia in late June, then bought Coherent and Micron the same week. Here's what the filing actually shows, and how each stock has moved since.
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.
Penguin Solutions (PENG) beat earnings for a seventh straight quarter and raised its outlook
Penguin Solutions (PENG) beat earnings for a seventh straight quarter, posting record $479 million in sales and $0.84 EPS, and raised its full-year outlook again. Shares fell in the regular session before jumping in after-hours trading on the beat.
A week ago I called my SK Hynix (SKHY) trade. I sold the $190 spike and bought the $154 dip.
David Han laid out a specific SK Hynix (SKHY) trade theory on July 7: a debut spike, Micron riding the sympathy wave, then a memory selloff as the excitement drained out. A week later it mostly played out, and he sold SKHY near $190 and bought back at $154. The original call is left exactly as written.
SK Hynix's $28 billion Nasdaq debut names Leopold Aschenbrenner's fund as a cornerstone investor
SK Hynix's record roughly $28 billion Nasdaq listing (SKHY) drew a cornerstone commitment from Leopold Aschenbrenner's Situational Awareness fund. The twist: the fund's single biggest disclosed position is a bet against the chip sector, which makes an anchor check into a memory chipmaker the story worth watching.
