❓ Why It Matters
Without portfolio rules, decisions become reactive and concentrated. Sustainable returns come from controllable risk exposure, not one-off bets.
🎯 How to Practice
Set target allocation by risk tolerance, rebalance by rules rather than headlines, and prevent hidden concentration from dominating portfolio behavior.
⚠️ Common Pitfalls
Diversifying superficially without true risk balance
Skipping rebalancing rules and drifting style
Judging portfolio health by short-term returns only
