The problem
Everything in investing gets measured except your decisions. The signal is in the pattern across many of them, and few keep track of theirs.
Feedback arrives one name at a time and stops at the headline return. It worked or not. The decisions underneath are where the insights are. Athletes have coaches, video, and play-level data to dissect what drives their performance. Analysts have the outcome and no objective read on what produced it.
- What your batting average is
- How much you make when right against what you lose when wrong
- Whether conviction and outcome line up
- How long you stay with a name after it stops working
- What the stock did after you moved on
Even the best investors are right only about half the time. The edge is in what they do during ownership, and it is the least measured part of the job.
How it works
Three steps to gain visibility into your decision-making
- 1
Build your portfolio
The names you are recommending, sized the way you would size them, in a $100 million paper portfolio. One sitting and your private record is live.
- 2
Let your decisions compound
Your portfolio updates daily at end-of-day prices, nothing to maintain. Every decision is priced, time-stamped, and immutable.
- 3
Watch the patterns emerge
Every decision is measured at 3, 6, 12, and 18 months. One of them tells you about an outcome. A hundred of them give you insights into how you operate.
The clock
When do the insights start to show?
Numbers appear from your first week. They start meaning something on this schedule, which begins the day your first decisions go in.
Six months
A first look at how you behave when a price moves with you and against you. The sample is growing with 40 to 60 decisions: coverage of 15 to 20 names, another 15 to 20 you know well enough to own, and 1 to 2 decisions on each.
Twelve months
Patterns emerge on batting average, average win and loss, and slugging. You have 80 to 120 decisions, of which 20 to 30 closed positions with the outcome settled. This is also when you first see how a stock performs after you sell.
Eighteen months
The signal gets clearer. The same decisions read at 3, 6, 12, and 18 months show whether a pattern held or faded with time.
Two years
You know your biases and you are countering them. That is a competitive edge over peers who never looked.

The reason it died was upkeep. There is none here. The portfolio updates at every close, and all you do is enter decisions you are already making.
