The AI stocks that led and lagged the first half of 2026
The first half of 2026 split the AI trade in two. Memory and chip-supply names like Micron (MU, +304%) and Intel (INTC, +278%) soared, while marquee names lagged and AI software fell, with Palantir (PLTR) down about 34%. Here is the full scoreboard and what it means.

AI investing glossary: the jargon behind every AI stock, explained
A plain-English glossary of the jargon in AI-stock coverage: GPU, HBM, foundry, neocloud, hyperscaler, capex, 13F, picks and shovels, Mag 7 and more, grouped by theme with links to fuller explainers.

AI's quiet winners: ASML, AMD and Vertiv VRT lead at the June 30, 2026 open
On the last trading day of the first half, the AI suppliers led again. ASML, Arm (ARM) and Vertiv (VRT) each rose about 4%, while Micron (MU) is up roughly 300% in 2026.

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.

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.

The market's closed, but the weekend stock tape is flashing green
The US market is closed, but stocks trade 24/7 on Hyperliquid. As of Sunday night the weekend tape is green, led by the chip names that fell hardest Friday. Our read before Monday's open.

What is a chip foundry? Why almost every AI chip is made by one company, TSMC (TSM)
Nvidia, Apple and AMD design chips but do not make them. A plain-English guide to what a semiconductor foundry is, the fabless model, why TSMC (TSM) makes around 70 percent of the world's chips, and the packaging bottleneck holding back AI.

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.

Our take: the AI sell-off looks overdone, and we think Micron gaps up tonight
The AI trade is in full panic and Micron has slid from over $1,200 toward $1,000 ahead of tonight's earnings. Here is why we think the sell-off is overdone and Micron could gap up.

The AI selloff isn't done, and now it's all about Micron
Asia rebounded overnight and Samsung jumped more than 9%, but the bounce didn't hold. AI and chip stocks are selling off again, most of the Magnificent Seven are red, and Micron erased its premarket gains. The market is still down on fear, and Micron's earnings tonight are the one thing that can break it.
