When you invested in that stock, or added to that mutual fund — did you think about how much to put in? Not what to invest in. Most of us think hard about that. We research, compare, ask around. But how much — as a deliberate, reasoned decision — is a question most investors never seriously ask. We invest what feels right. What feels comfortable. What we happened to have lying idle. And in doing so, we make one of the most consequential decisions in our financial lives almost entirely on instinct. There is a better way to think about this. And it comes from an unlikely place. The Man Who Worked at Bell Labs John Kelly was a physicist at Bell Labs in America in the 1950s — the same place where Claude Shannon invented information theory, which we explored in the Shannon's Demon post. In 1956, Kelly asked a precise question: If you have an edge,  How much should you bet to maximize the long-term compound growth of your wealth while avoiding eventual ruin? The answer he arr...

You are reviewing your portfolio at the end of the year. The app shows a green number. Your fund returned 14.2%. The Nifty 50 returned 11.8%. Your fund manager beat the benchmark. You feel good.

But here is what matters. If you don't know why a fund outperformed, you cannot know whether it will do so again. Returns Are a Destination. Attribution Is the Map. Think about how we talk about fund performance in India. Your friend says: ...

Picture this scene, which plays out thousands of times every day in the investing world. A company reports strong quarterly results. Revenue up. Profits up. Management raises guidance. The business is clearly doing well. Analysts upgrade their ratings. Financial news channels run segments on it. Your colleague at work mentions it over chai. Everyone agrees: this is a good company. So you buy the stock. And then, slowly and confusingly, the stock goes nowhere. Or worse — it falls. Not because the company turned bad. Not because the results were wrong. The business continued to grow exactly as expected. And yet, the stock disappointed. This is one of the most common and most disorienting experiences in investing. And understanding why it happens is at the heart of what Howard Marks — founder of Oaktree Capital Management and one of the most widely read investment thinkers of our time — calls second-level thinking . The Problem With Obvious Answers Marks begins with a deceptively ...
