From Macro View to Position: How I Build a Trade

Published · 15 May 2026 · 7 min read

A macro view is not a trade. This is the process I use to translate a top-down read on the economy and policy into a specific, sized, risk-defined position — and the questions that have to be answered before any capital is committed.

Key Takeaways
  • A thesis without an instrument, a size, and an invalidation level is an opinion, not a trade
  • The instrument should express the cleanest version of the view with the least unrelated risk
  • Position size is set by the distance to invalidation, not by conviction
  • Every trade needs a pre-defined level or condition that proves the thesis wrong
  • Correlation across the book matters more than the merit of any single idea
Start with the regime, not the ticker

Every position I take begins one or two levels above the instrument itself. Before I think about what to buy or sell, I want a clear read on the prevailing regime: the direction of growth, the path of policy, the behaviour of liquidity, and where the market's consensus is currently positioned. The trade is downstream of that read.

The most useful question at this stage is not "what do I think will happen" but "what is already priced." A view only has value where it diverges from consensus. If the market and I agree, there is little edge — the move has largely happened. The opportunities worth sizing into are the ones where the data, the policy path, or market structure point somewhere the crowd is not yet positioned.

Translate the view into the cleanest instrument

A single macro view can usually be expressed a dozen ways, and most of them are dirty — they carry exposure to things that have nothing to do with the thesis. The discipline is to find the instrument that captures the view with the least unrelated risk.

If the read is on real rates, an outright equity position drags in earnings, sector rotation and idiosyncratic risk that dilute the bet. A rates instrument, a relative-value pair, or an options structure may express the same view far more cleanly. I spend more time on instrument selection than most people expect, because a good thesis in the wrong vehicle is how you can be right and still lose.

Size from the stop, not from conviction

Conviction tells you whether to take a trade. It does not tell you how large to make it. Size is a function of one thing: the distance between entry and the level that proves the thesis wrong. I fix the dollar risk per trade first, then let the invalidation distance dictate the position size — never the other way around.

This is where the tools on this site come from. ATR-calibrated position sizing, R-multiple planning, and portfolio-weighted contribution are not academic — they are the mechanics that keep a single idea from being able to do outsized damage. A high-conviction trade with a wide stop gets a smaller position than a moderate-conviction trade with a tight one. That feels counterintuitive until you have watched conviction-sized positions blow holes in a book.

Define invalidation before entry

The single most important sentence in any trade I take is the one that describes how I will know I am wrong. It has to be written before the position goes on, because afterwards the mind is very good at moving the goalposts. Invalidation can be a price level, a data print, a policy outcome, or a structural break — but it must be specific and it must be decided in advance.

A trade without a pre-defined invalidation is not a trade, it is exposure with a story attached. The discipline of writing it down first is what separates a process from a series of hopeful guesses.

Check the trade against the whole book

No position exists in isolation. Before adding anything, I look at what it does to the portfolio as a whole: does it concentrate an existing exposure, hedge it, or introduce something genuinely new? Three "different" trades that all depend on falling real yields are one trade in three costumes, and the book is far more fragile than it looks.

Managing correlation across the book is, over time, more important than the merit of any individual idea. The goal is a set of positions whose risks are as independent as possible, so that being wrong on one does not mean being wrong on all of them at once.

Frequently Asked Questions
How do you decide which instrument best expresses a macro view?
I look for the vehicle that captures the thesis with the least unrelated risk. If the view is on rates or the dollar, expressing it through single-stock equity drags in earnings and sector risk that have nothing to do with the bet. The cleanest instrument is usually a relative-value pair, a rates or FX instrument, or a defined options structure.
Should position size scale with conviction?
Not directly. Conviction decides whether a trade goes on at all; size is set by the distance to the invalidation level so that dollar risk per trade stays consistent. A high-conviction idea with a wide stop can warrant a smaller position than a lower-conviction idea with a tight one.
What counts as a valid invalidation level?
Anything specific and decidable in advance — a price level, a data outcome, a policy decision, or a structural break in the market. The key is that it is written down before entry, so the decision to exit is not made in the heat of an adverse move.
