Markets
Indices, sectors, interest rates and inflation, with figures from central banks and statistics offices.
Decisions
Every investment decision recorded with its reasoning, and reviewed against what happened.
Reporting
Ownership kept in units, a year-end close checked line by line, and a full annual report for every co-owner.
Research

About
Patient capital, plain reporting.
Balk Investmentbolag is a simple partnership in Umeå, where a small group of co-owners invest their own capital together. We start from fundamental analysis, not short-term market moves, and ask one question of every company: would we want to own it even if the stock market closed for five years?
Each investment must pass two criteria: the quality of the business, then its price. Every decision is written down with its reasoning and what would prove it wrong, and reviewed over time.
Long-term
Holdings measured in years, not speculation.
Concentrated
A few holdings we understand well, not diversification for its own sake.
Accountable
Every decision recorded with what would prove it wrong, and reviewed.
Transparent
A full annual report to every co-owner, every year.
Results
Full reporting, every year.
Co-owners receive detailed results in our annual report. In brief:
Time-weighted return on the investments from 15 July to 30 September 2026, before the firm's running costs. OMXS30, a price index, rose 3.21% from the start on 13 July. Past returns are no guarantee of future returns.
