Welcome to Building Arks
I am an experienced investor writing about stocks that I think can produce 15% compounded returns over a 5-10 year time horizon. I invest long term and for value, and I publish the work I have done for my family’s portfolio.
How I invest
I have no strict rules and see flexibility as an advantage. I try to invest in great assets for long-term value. I think my advantage is psychological, not informational. I run a concentrated portfolio with a long tail. I don’t measure performance because doing so makes me a worse investor. More on my Stockpicking, Mental Models, and Portfolio Structure pages.
About me
I spent 20 years as an equity fund manager, working for Baillie Gifford, Findlay Park, and Brown Advisory in the UK and covering both developed and emerging markets. I adored the intellectual challenge of investing but increasingly found that wanted to build businesses as well as analyse them - so now I split my time between stock-picking for my own account and advising/directing start-ups. I love and learn from both.
What you’ll get
I publish the research I do for my own account.
I write for busy people. I write concisely and in consistent formats, so that you can read my posts fast but still get what you need.
I will publish 2 kinds of posts:
Initiations, focusing on what really matters.
Updates, with thesis/valuation changes, numbers, and bullet point notes.
