I'm Ed Croft, Co-Founder and CEO of Stockopedia. Like a lot of investors, I learned the hard way that too much conviction and overconfidence can come back to bite you in the markets. So I went looking for a better approach — and found it in the academic evidence on rules-based investing.
That conviction is what drives the development and ethos of Stockopedia. Everything here is built with one aim: helping you take the research-backed route to investment success. Picking better stocks with the power of the StockRanks — Quality, Value, and Momentum. Making your research more effective, more efficient, and honestly, more enjoyable. And creating a space where we all keep levelling up as investors.
That’s what I write about here. I hope you find it useful.
Rules- based. I'm a huge believer in the power of rules-based investing to dramatically improve long-term outcomes in stock markets. The investment industry often doesn't have the individual's best interests at heart. So self-directed investing really is the way forward. But if you're going to be self-directed, you have to learn to manage your monkey mind. Otherwise, we end up making all kinds of mistakes due to behavioural biases: FOMO, overconfidence, overtrading, overattachment, loss aversion, and more.
I have a simple framework I call the 3D investment framework, and it guides everything I do.
There's too much to go into here, but I write a lot about the NAPS investment process on the site and share a lot of research findings into more active approaches, too. These generally guide my own investment choices as an individual and in managing investments for my family.
