Advanced risk & diversification

🎯 Goal: Understand diversifying across assets/sectors lowers risk without giving up all expected return.
Diversification = not all eggs in one basket, spreading across assets and sectors that move differently. When one drops, others may offset → lower overall risk.

Let’s explore

🧺
Spread across less-correlated assets/sectors → smoother overall swings.
⚖️
It cuts specific risk (one company), not overall market risk.
🔁
Periodically rebalance to keep target proportions.

Practice activity

🧠 Why is holding 1 stock riskier than a fund of 50 stocks?
Worked example: Hold 1 stock: if that firm fails, you lose a lot. Hold a fund of 50 firms across sectors: one bad firm barely matters as 49 offset it → specific risk drops sharply.

4. "Rebalancing" a portfolio to?
→ Keep target proportions
5. 1 stock vs a 50-stock fund?
→ Riskier
