About

Hello, I’m David.

For years I’ve watched a small group of technology companies quietly become the infrastructure everything else runs on.

Not the flashy ones chasing the next narrative, but the ones embedded so deeply in the global economy that removing them would cause genuine disruption.

North Tech Capital dot com is where I write about them.

What I publish

Every week I write about the businesses I follow: the thesis, the risks, what the market is getting right or wrong, and what I’m watching. It’s free.

The North Tech 15

The North Tech 15 is my own retirement portfolio with a mandate to hold no more than 15 of the world’s largest AI and semiconductor companies. It’s run to strict rules and it has been live since 5th August 2024.

You can follow every position and performance in the portfolio community.

I publish a monthly fact sheet with positions sizing and performance against the Nasdaq-100, attribution, risk metrics, drawdowns and more for transparency.

How I think about investing

I run a concentrated portfolio because conviction matters more to me than coverage and looking after a smaller basket of high performance businesses is efficient and practical.

When headlines create pressure to sell, I go back to the fundamental ballast that made me enter a position in the first place.

If the thesis holds, the position holds.

You can read exactly how it’s built and on the Strategy page.
