Episode 11. Diversification in Practice How Many Positions, and How Should You Split Them? Before We Begin: Diversification Isn’t for “Higher Returns” — It’s for “Not Breaking” When people hear “diversification,” they often misunderstand it: “Doesn’t diversification reduce returns?” “Isn’t it better to go big on one great stock?” In practice, diversification is less about maximizing upside and more about preventing a single mistake from becoming the end of the game.

Episode 10. Split Entries & Split Exits How to “Build” a Position Without Breaking Your Mind Before We Begin: One Big Decision Creates One Big Emotional Swing In Episode 9, we defined exit rules: stop-loss vs take-profit. But even with rules, real markets trigger common conflicts: “This feels like the bottom—I want to go all-in.” “I’m in profit… should I sell everything?” “If I sell now, it might keep rising. If I don’t, it may fall back.” These conflicts don’t happen because you’re not smart enough. They happen because you’re trying to finish the decision in one shot .
