Money market funds invest in short-term debt instruments like treasury bills to provide a safe place for savings with low returns. Bond funds invest in government and corporate debt and aim to provide income but carry more risk than money market funds. Balanced funds contain a mix of bonds and stocks, typically 60% equity and 40% fixed income. Equity funds focus on long-term capital growth through stock investments. International and global funds invest overseas to provide currency and geographic diversification to portfolios. Specialty funds target specific sectors, regions, or socially responsible criteria. Index funds replicate the performance of broad market indices.
