Diversification, correlation, and risk-return
Diversification involves spreading investments across various assets to reduce exposure to any single risk. Correlation measures how asset prices move in relation to each other; low or negative correlation among assets enhances diversification benefits. The risk-return tradeoff refers to the principle that higher potential returns are typically associated with higher risk. By diversifying assets with low correlation, investors can potentially lower portfolio risk without sacrificing expected returns, achieving a more efficient balance between risk and reward.

💡 Key Takeaways
- Understand diversification: spreading investments across different asset classes to reduce exposure to any single risk.
- Learn how correlation affects diversification, with low or negative correlations helping assets move differently.
- Grasp the risk–return tradeoff: higher potential returns usually involve higher risk, while lower risk often means lower returns.
- Apply basic diversification ideas by combining various asset classes, sectors, and geographic regions to fit your risk tolerance.
❓ Frequently Asked Questions
What is diversification?
Spreading investments across different assets to reduce the impact of any one investment's poor performance.
What does correlation mean in investing?
A statistic that shows how asset prices move in relation to each other, ranging from -1 (perfectly opposite) to +1 (move together); 0 means little to no relation.
Why is low or negative correlation beneficial for diversification?
If assets don’t move in sync, losses in one asset can be offset by gains in another, reducing overall portfolio volatility.
What is the risk-return tradeoff?
Higher potential returns generally come with higher risk; to pursue greater returns, you typically accept more risk.
How can you build a diversified portfolio?
Include different asset classes (stocks, bonds, cash equivalents, real estate), across sectors and regions, and rebalance periodically.
