SEBI re-categorized mutual fund schemes in 2017 to bring uniformity across fund houses and make investing easier for investors. The document outlines the various types of mutual fund schemes in India, including equity schemes, debt schemes, hybrid schemes, and solution oriented schemes. Equity schemes invest primarily in stocks and are further divided into 11 categories like large-cap, mid-cap, small-cap funds. Debt schemes invest in fixed income instruments and money market securities across 16 categories based on maturity and credit risk. Hybrid schemes combine equity and debt assets, and solution oriented schemes have lock-in periods tailored for retirement or children.
