Sunday morning briefing for the stocks you own

Not your average newsletter

Built entirely around the stocks you own — not the market, not the sector, not what everyone else is watching.

Yours, not theirs

Every brief is generated specifically for your holdings. Two investors with different portfolios get different emails.

No dashboards. No digging.

You don't open an app. You don't run a search. The intelligence arrives. You read. You act or move on.

Beyond the news feed

Supplier signals. Competitor moves. Ecosystem shifts. The signals that never appear in your companies' own news.

Honest, not optimistic

When your thesis is intact, we'll say so clearly. When something's worth watching, we won't bury it.

What's inside every Sunday?

Six sections. Ten minutes. Everything that matters for your portfolio this week.

Each issue covers what happened inside your companies this week, what's shifting in the ecosystems around them, and whether anything changed that you should know about. No summaries of things that don't apply to you.

The further you go, the sharper it gets. Aphelion learns what matters to you over time — which signals you act on, which you ignore, and where your thinking tends to drift.

Every portfolio has a turning point. Yours arrives Sunday morning.

Who built this

And why this newsletter exists.

I'm Alex, I've been interested in markets since I was 14. Investing for nearly a decade.

Over the years, I built a concentrated portfolio around one idea: the technologies that will define the next decade. AI infrastructure. Autonomous systems. The crypto economy's picks and shovels. Companies, I believe in enough to hold through the drawdowns.

The problem was staying close to that conviction without it becoming a second job. I couldn't find anything that knew my thesis and told me what actually mattered each week — so I built it.

Aphelion is an AI-native product. I don't write each email by hand — I built the system that does. Every Sunday brief is generated by AI trained to understand your specific holdings, your thesis, and what shifted around your companies that week. I'm the first user. Every Sunday morning, I read the same email you'll receive. When something isn't sharp enough, I fix the system.

Built this for myself — hoping it's useful for you too. If it's not, I want to know.
