I’ve been in the markets for about thirty-five years. Buy-side the whole time, which means I wasn’t selling anything to anyone, I was responsible for investment results. For part of that run I was Head of Equity Trading at Northern Trust, where it was my job to move large amounts of money through the market without making expensive mistakes.
You’d think, after enough years of that, the lesson would be “get smarter”. It wasn’t. The lesson was almost the opposite.
The thing I kept seeing
Here’s what struck me, over and over. The people losing money usually weren’t dumb. They had good information, good instincts, and a real understanding of the companies they owned.
And they got hurt anyway, because at the exact moments that mattered most, they did the human thing instead of the right thing. They bought more of what had been going up, right before it stopped. They sold good companies in a panic at the bottom. They fell in love with a story and stopped looking at the facts. They held a sinking position because selling would mean admitting they were wrong.
None of that is a knowledge problem. It’s a behavior problem. And behavior problems don’t get solved by knowing more — they get solved by building something that takes the decision out of your hands at the moment you’re least able to make it well.
How I learned this lesson
The value of having a system in place became crystal clear to me in October 1987 when the market had its worst one-day drop in history. Even though I was working for a hedge fund at the time and should have known better, my emotions got the best of me, and I sold nearly every position that I owned. The very next day I realized how ill-advised that decision was. When the market opened the following Monday morning I bought everything back, took a small haircut (the cost of learning a valuable lesson), and I have never repeated that behavior again.
What I eventually understood about myself
I thought I was different. I had the experience, I’d seen the cycles, surely I could trust my judgment in the moment.
I couldn’t. Not reliably. Nobody can. On a bad morning, with a position moving against me and my gut screaming, my judgment was worth a lot less than I wanted to believe. What actually protected me — every time — wasn’t a better feeling. It was a rule I’d written down in advance, when I was calm, that I’d agreed to follow even when I didn’t want to.
That’s the quiet truth underneath good investing. It’s not about being a genius in the moment. It’s about being disciplined enough, in advance, so that you don’t need to be a genius.
So I built a system
Over years, I turned that idea into something concrete: a process that scores companies the same way every time, decides what to own and what to drop on rules instead of moods, and (this part matters) pays attention to the overall weather of the market, so it knows when to lean in and when to pull back and hold some cash.
It doesn’t get scared. It doesn’t fall in love. It doesn’t front-run my own panic. It just runs the process, the same way, in good markets and bad. My job is to run it with discipline and to know when the broader environment is telling me to be cautious. The system’s job is to keep me from being my own worst enemy.
I call it Zen Alpha. The “Zen” isn’t decoration — it’s the whole point. Calm, consistent, unbothered. The opposite of how most people actually invest.
What I’m going to do over the next few weeks
I’m going to show you how this works. Not the secret sauce, but enough that you can see it’s real, understand how it thinks, and look at what it’s actually done.
In the next piece, I’ll get into how I think about investing. The handful of principles the whole system is built on. After that, what it actually looks at when it sizes up a company. Then the part most people care about: does it work, and how do I know.
By the end you’ll have everything you need to decide whether this is for you. And it genuinely might not be — it’s built for patient, long-term investors who’d rather follow a disciplined process than chase the next hot thing. If that’s not you, no harm done.
But if any of what I just described sounds familiar — if you’ve ever watched yourself do the human thing and regret it — keep reading. This was built for exactly that.
