I'm the editor of UK Value Investor, an investment website and newsletter for defensive value investors. I have been an investor since the 1990s and since 2010 I have been developing and applying a "defensive value" approach to building a high yield, low risk share portfolio. This strategy is unique in that it focuses on a series of quantitative financial measures that look back through 10 years of financial results to find companies that have the best combination of quality and growth at the best prices. I also write the blog at UKValueInvestor.com, and occasionally publish other content such as guides and spreadsheets. Having left school at 16, I trained as a mechanical engineer but later switched to a career in insurance software. That lasted for more than a decade until I started my newsletter business in 2011. My book, “The Defensive Value Investor”, covers my investment strategy in detail.
