The GemFilter Philosophy

We believe investing success is 80% psychology and 20% spreadsheets. Every essay here is written to help you become the kind of investor who stays rational when markets panic, who seeks intrinsic value over price, and who thinks in decades rather than days. Our framework is rooted in Benjamin Graham's The Intelligent Investor and refined by decades of Warren Buffett's shareholder letters.

Value investing is not a get-rich-quick strategy. It is a long-term mindset built on discipline, patience, and the ability to act when others react. Warren Buffett's philosophy — "be fearful when others are greedy, and greedy when others are fearful" — is simple to understand but extraordinarily hard to practise. These essays exist to help you practise it.

We draw from proven frameworks including value investing theory, behavioural finance, and the principles of intrinsic value estimation. Ready to analyse a stock using these principles? Use our checklist →
