Diversification is key to investment success. A diversified portfolio spreads your investment risk, opens opportunities and aims to deliver smoother returns in the long run.
A diversified portfolio can take many shapes. For example, you can choose to invest across different asset classes, sectors, or geographies. One way to do this is by investing in a mutual fund, which pools money from multiple investors to invest in a diversified portfolio of securities. The investments in a mutual fund are categorised by:
Asset class: E.g. Equity, fixed income, cash, or commodities.
Instrument: E.g. Liquid funds or long-duration bonds for fixed income; large, mid, and small cap stocks for equity.
Sector: E.g. Technology, healthcare, finance, energy.
Geography: E.g. India, Asia, emerging markets, global.
