The Power of Diversification

Want to reduce risk without sacrificing returns? That's the power of diversification.

The smartest next move isn't always chasing higher returns — it's finding an investment that's uncorrelated to the rest of your portfolio. When done right, this approach improves your risk-adjusted performance and builds a more resilient portfolio.

We assume five investments, each with 15% expected return, 15% standard deviation, and 5% risk-free rate. Here's what happens as we diversify:

• From 1 to 2 investments: Risk drops 29.3%, Sharpe ratio improves 40.3% (from 0.67 to 0.94)
• From 1 to 5 investments: Risk drops 55%, Sharpe ratio improves 122% — all while maintaining a 15% expected return

This is diversification in action: lower risk, higher efficiency, same return. No wonder it's called the only free lunch in finance.
