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.
I let Claude AI trade $100 on Robinhood, week 3: it sold MSTR right at the low and it gapped up 6% the next morning
The AI running my $100 Robinhood account cut MicroStrategy (MSTR) at $90.93 on Monday. Tuesday morning MSTR gapped up about 6%. It drives me insane, but the deal was that Claude makes the calls, so I am letting it ride.
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.
A farming stock jumped 51% overnight by rebranding into AI real estate
Braiin (BRAI), a farming tech company, jumped 51% on a single press release announcing an AI real estate product. Volume spiked 230 times normal. Here is the pop, and the risk behind it, compared with the real AI real estate trade in Equinix and Digital Realty.
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.
Intel hired away SK Hynix's memory boss, and nobody's pricing that in yet
The government owns 10% of Intel. It hired SK Hynix's former CEO to run advanced packaging, not to build DRAM. Here's why that combo, plus July 23 earnings, has me watching INTC closely.
I let Claude AI trade $100 on Robinhood, end of week 2: it dumped RCAT at a 13% loss and bought MSTR instead of anything I wanted
Claude, the AI running my $100 Robinhood agentic account, finally cut Red Cat at a 13% loss. Then it ignored every discounted ticker I suggested and put nearly the whole account into MicroStrategy. End of week 2 letting Claude trade my money.
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.
T1 Energy (TE) is down today while tech rallies. Here's why I added to my position anyway.
T1 Energy (TE) fell about 1% today while the Nasdaq and tech sector rallied. Short interest is high, a Fuzzy Panda short report is still unresolved, and there's unconfirmed chatter on X that Leopold Aschenbrenner sold his stake. I added to my position yesterday anyway. Here's why.
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.
My $100 Claude AI trade in RCAT: still holding, week 2
The Robinhood Agentic AI's first pick, Red Cat (RCAT), is down about 5% heading into week 2. Here is why I am not selling, the real drone-program news that came out over the holiday, and where the cut line and target still sit.
Why I bought a small position in SharonAI (SHAZ)
I picked up a small SharonAI (SHAZ) position Thursday near the lows. Here is the Nvidia deal, the Leopold Aschenbrenner and Anthropic angle, and the real risks a short report raised.
I let Claude AI trade $100 of my money and it bought Red Cat (RCAT)
I funded Robinhood's new Agentic AI account with $100 and let Claude trade for me. Its first pick was Red Cat (RCAT) at $10.68, an Army drone stock I would not have grabbed myself. Two days in, it is green, and I still cannot fully explain the pick. My honest, slightly humbling take.
Applied Optoelectronics (AAOI) popped today and I'm still long. Here's my real thesis, and why I'm ignoring the AMD rumor.
Applied Optoelectronics (AAOI) jumped about 9% today. My take: the real thesis is the $1.1B-plus revenue guide, the $200M 1.6T order, and a 6x capacity ramp. The AMD talk is unconfirmed X chatter. I'm long, here's how I see it.
Nokia ($NOK) had a rough week, and I'm still holding
Nokia got smoked in June after a 170% run. The Nvidia deal, the BlackBerry mix-up, the chart, and why I'm still holding $NOK into July earnings.
