What is the core-and-satellite strategy for investing?

A core-and-satellite portfolio is an investment strategy that divides the money into two parts: "core" and "satellite," Moneycontrol reported. The “core" usually accounts for nearly 60-80% of portfolio and comprises low-cost funds. It's designed to provide steady returns. The remaining 20–40% forms the satellite portion, typically invested in mid- and small-cap funds with higher growth potential.
