In this video, I explain the definition of Alternative Investment Funds (AIF) in India as per the SEBI AIF Regulations 2012. I cover key aspects such as the privately pooled nature of AIFs, the types of investors involved, and the necessity of a defined investment policy. I also explain the various types of investment funds, including venture capital funds, private equity funds, debt funds, infrastructure funds, angel funds, SME funds, hedge funds, social impact funds, and corporate debt market development funds. I detail the characteristics and investment strategies of each fund type.
