Diversification: A Portfolio Learning Concept

Why concentration and diversification are important concepts in investing education.

Diversification means spreading exposure across different assets or securities rather than depending on a single outcome. It can reduce concentration risk, but it cannot remove market risk.

Students should learn correlation, sector concentration, position sizing and time horizon. A diversified portfolio can still fall when broad markets decline.

Use diversification as a risk-management concept, not as a promise of protection or returns.
