Modern Portfolio Theory (MPT) helps investors balance risk and reward through smart diversification. Instead of relying on a single asset, MPT spreads investments across different classes to reduce volatility and protect capital. This becomes especially powerful when dealing with unlisted shares—high-growth opportunities that often carry higher risks due to limited information, uncertain valuations, and low liquidity. By combining them with safer assets, investors can capture upside potential while safeguarding their wealth. Platforms like Sharescart make it easier to access these opportunities, enabling systematic and data-driven investing for a more secure financial future.
