fundsdiversification

Funds diversification is the practice of spreading an investment portfolio across multiple investment funds to reduce risk and improve potential risk-adjusted returns. By combining funds that invest in different asset classes, regions, sectors, and investment styles, investors seek to reduce concentration risk associated with any single fund or market segment.

A core principle is that diversification benefits depend on the correlation between fund holdings. Funds with low or negative correlations tend to reduce portfolio volatility. Common approaches include asset allocation across stocks, bonds, cash or alternatives, and the use of index funds and exchange-traded funds to achieve broad exposure efficiently.

Implementation involves defining objectives and risk tolerance, selecting a mix of funds with complementary exposures, and considering costs such as management fees and taxes. A target allocation is established and periodically rebalanced to maintain diversification. Responsible diversification also considers fund sizes, turnover, and overlap among holdings.

Limitations include the impossibility of eliminating systematic market risk, potential for over-diversification or asset overlap, and added complexity and fees. Currency risk, tracking error in index funds, and fund closures are additional considerations. Diversification should align with long-term goals and liquidity needs.

Common implementations include a three- or four-fund structure (for example, broad stock fund, broad bond fund, international fund, and cash or short-term fund), or a fund-of-funds approach. Investors may also diversify across managers and investment styles to avoid style drift.
