The core-satellite investing strategy is a portfolio construction approach designed to balance returns, risk, and costs by combining passive and actively managed investments. According to reports from Mint, the core forms the foundation of an investment portfolio, typically consisting of passive investments such as index funds or exchange-traded funds (ETFs) that track benchmark indices, providing broad diversification at a relatively low cost. The satellite component represents additional investments that investors actively select, including actively managed funds, sector-specific investments, thematic opportunities, or individual stocks designed to generate returns above the benchmark.
As reported by Mint, Prabhakar Kudva, Director and Principal Officer – Portfolio Management Services at Samvitti Capital, suggests a typical allocation of 80% to the core portfolio and 20% to the satellite portfolio. According to Kudva, the core should be built around secular growth themes and sectors, while the satellite portion is more opportunistic and actively managed. He emphasizes that the core portfolio provides stability and supports long-term wealth creation, while the satellite allows investors to seek incremental alpha. The principle matters more than the exact numbers, with the core remaining the majority component.
According to Mint reports, investors should review and rebalance their portfolios periodically to ensure allocations remain aligned with objectives. Kudva recommends reviewing the portfolio at least once every quarter, preferably during earnings season. He explains that reviewing more often than quarterly usually invites noise and overtrading, while quarterly reviews anchored to earnings provide clarity on company performance against original thesis and whether secular stories remain intact.
As reported by Mint, the core-satellite strategy offers several advantages including combining core investments with growth-oriented satellite investments to achieve the right mix of passive and active management. The core portfolio acts as a stable foundation cushioning market volatility impact, while satellite investments help earn better returns in bull phases. However, the strategy has limitations including no fixed rule for ideal core-satellite split, potential for choosing wrong allocation resulting in excessive risk or lower returns, and satellite investments may fail to generate expected excess returns even in bull phases.
