Hi there. I'm **Ed Page Croft**, co-founder of [Stockopedia.com](https://www.stockopedia.com) and self-confessed stock market nerd. I'm obsessed with building market-beating portfolios of shares, with the minimum of effort while avoiding excessive risk. This website is a growing repository of short-form notes about how to do this, using the ultimate hack - **rules-based investing**. ## What you'll find here If you want to understand what really works in stocks, you'll feel right at home. You’ll find rules of thumb for better decision making based on the evidence of what's always worked in the past. Start by working through the notes below, or using the sidebar and exploring the links in each. Most concepts here are backed up with evidence from academic finance, research studies and market history. - Successful investing begins with [[self reliance is the path to investment success|self reliance]]. - Becoming self reliant requires [[manage the monkey mind|managing yourself]]. - Managing yourself is made easier by applying [[simple rules beat human judgement|simple rules]]. - Simple rules should be based on [[What works in stocks?|what works]]. - Instead of falling for stories, [[expose to return drivers]]. - Instead of betting big, [[diversify for resilience]]. - Instead of winging it, [[maintain your discipline]]. - What works is easy to understand, but needs solid routines to implement. Please use the links above, or in the sidebar to browse. I try to keep a list of [[What's new?|what’s new here]]. And if you’d like to know why I’m writing notes in this format, you can [[About|learn more here]]. --- The easiest way to follow along as this site develops is via Twitter/X [@edcroft](https://www.twitter.com/edcroft) where I will post updates.
