From the desk of Magnus · FounderLund, Sweden

This is a tool I built because the one I wanted didn't exist.

Most investment software is built for traders: dashboards full of blinking numbers, short-term signals, and noise. I wanted something built on a different premise: that investing is fundamentally an intellectual act. Read the business first. Understand the moat. Judge the management. Only then count the numbers.

Value investing, at its core, is about following your principles regardless of what the crowd is doing. That requires a certain kind of freedom: the freedom to underperform the market for stretches because you believe you are right in the long run, to hold when others are selling, to pass on things that feel exciting but fail your written criteria. Money makes that freedom possible. It is not the end; it is what keeps you in the game long enough for the good decisions to compound.

Here is the honest version. I am not a good trader, and after twenty years I have stopped pretending otherwise. When a position moves against me I feel it: I check the price too often, I sleep badly, and the stress is a real cost. The year I started following investors on X, my performance measurably dipped, because I did not have enough conviction to hold on or buy more when the price dropped. Most mistakes I have made came from FOMO, fear, or listening to others. Almost none came from the businesses themselves. investboard exists because I needed a process stronger than my own temperament: a written thesis, a kill criterion set in advance, watchlists that give the research structure and save time, every position tracked against its risk factors and its margin of safety, and a briefing that speaks only when something has actually changed against your own criteria. The discipline does not come from willpower. It comes from having done the work beforehand and written it down.

I have run my own book for over twenty years, compounding at roughly eighteen percent a year. The work I enjoy most is the reading (annual reports, letters, trying to understand the moat and the future of a business) and sharing what I find with people who find it equally interesting. If you want to read and listen the same way, I keep a curated list of books and podcasts by investors with real track records.

The process you will find in this product is not original. It is cloned, deliberately, from investors who have proven it works over decades. Graham's margin of safety. Buffett's moat framework. Munger's mental models and inversion. Pabrai's checklist discipline. Lynch's business common sense. Druckenmiller's forward-looking conviction. Cloning the best is itself a principle: why reinvent a method that Buffett has compounded at twenty percent for sixty years? The only contribution here is the tool that makes it easier to apply consistently.

If you read fund letters more than you read Twitter, if you have written down a kill criterion and lived by it, if you would rather wait three years for the right setup than chase ten wrong ones — this was built for you.

Magnus has spent twenty years running a concentrated personal book of fundamentally underwritten businesses. The portfolio compounds at roughly eighteen percent a year, verified through his Avanza Bank brokerage account. The methodology is qualitative first (moat, management, culture), then quantitative: margin of safety, normalised earnings, valuation gap. The analysis serves the thesis, not the other way around.

He builds investboard for the same reason he invests: because the work itself is worth doing. The reading, the pattern recognition, the intellectual delight of watching a thesis play out over years. Every feature exists because Magnus needed it, used it, refined it, and shipped it, first to himself, now to you.

Behind the number

What twenty years actually taught me.

  1. 01

    The returns came from a handful of obvious bets.

    Held long term, but never to a calendar. A position is held until the story changes or the price becomes highly overvalued; nothing else forces a sale. Bets that obvious arrive rarely, so the discipline between them is patience, and the temptation between them is the real risk. New positions are sized as a percentage of the portfolio, never as an amount of money.

  2. 02

    Waiting is not enough.

    The position that cost me the most did not fail because I held too long. It failed because I stopped keeping up. Reading, staying current, understanding why something is moving: that is the actual work. Compounding rewards holding only while the story holds, and you only know the story holds by doing the reading.

  3. 03

    Price follows earnings, eventually.

    In the long run the stock follows the business. Sentiment sets the price this quarter; earnings set it over a decade. Everything on this page, and in this product, is built on that one assumption. It is why the horizon here is ten years and up, and why I listen to managements like Amazon that take every right decision for the long term, even when the quarter looks worse for it.

  4. 04

    Character compounds too.

    I have been lucky with role models, people whose principles were larger than life, and what they taught me had little to do with markets. What character means. How to treat other people. Be genuinely kind, not performatively kind. Think before you speak. Know your own flaws, because they follow you into every position you take.

  5. 05

    Guard the quiet.

    Meditation, journaling, training, sleep: the habits that keep judgment clear. Ego muddies the mirror you are trying to see the world in, and the daily work is polishing it. The same quiet is where independence lives. I never accept the consensus view; I try to crack the code for myself, follow my own read, and accept that there will be dips. The dips are part of the price.

What we believe

Six principles, the rest is plumbing.

  1. 01

    Qualitative first. Quantitative always.

    We read the filing before we run the model. Understanding the business (its competitive position, its culture, the quality of its management) is the primary analysis. The margin of safety calculation is its conclusion, not its beginning. Numbers are precise; insight is prior.

  2. 02

    A few great ideas, held with conviction.

    The goal is not to own thirty businesses you half-understand, but three you know deeply. Every major insight in investing comes from spending more time than others on fewer things. Breadth is a symptom of uncertainty. Concentration is the reward for clarity.

  3. 03

    Process over prediction.

    We do not forecast markets, score sentiment, or sell signals. The product is a repeatable underwriting process (moat, management, margin of safety) applied identically to every company you research. Discipline travels; predictions don't.

  4. 04

    Idea first. No screening.

    Start from a narrative, a misunderstanding by consensus. Ideas come from two places only: going deep on a single business, or a long-term trend you genuinely understand. Then ask whether it can be mispriced, not the other way around. Screeners find cheap stocks; they do not find great businesses underappreciated by the market. The insight comes first, the valuation is its test.

  5. 05

    Value investing is forward-looking.

    One hundred percent of the information you have about any business reflects the past. One hundred percent of its value depends on the future. We do not project the recent past into the future; we visualise where the business will be in ten years and ask whether today's price accounts for it. In the long run the price follows the earnings. The job is to be right about the earnings.

  6. 06

    Freedom is the real return.

    The number in the portfolio is not the goal. The goal is independence: the freedom to do work that matters to you, live by your own calendar, and say no to things that waste your one life. Seneca wrote that life is long if you know how to use it. Compounding is how investors use it.

What we don't believe in

The omissions are the product.

Every absence below is a design decision, not a backlog item.

  • —

    No push notifications.

    A briefing arrives once after the close. If you need to be interrupted to manage a portfolio, the portfolio is not built for compounding.

  • —

    No intraday ticker tape.

    No candles, no heatmaps, no "your portfolio is up 0.3%" widget. Daily prices are noise; the briefing speaks only when something has actually changed against your written discipline.

  • —

    No homepage feed of trending stocks.

    Crowds are a leading indicator of bad ideas at high prices. We will not put a "what's hot" panel in front of an investor on their way to underwrite a business.

  • —

    No auto-trading. No managed money.

    The decision belongs to you. We will never insert ourselves between an investor and their broker.
