Alternative Investment Funds (AIFs) are pooled investment vehicles that are not covered under traditional investment options like mutual funds. Categories of AIFs include Category III AIFs, which encompass hedge funds and other funds trading with a view to profiting from short-term market movements or taking arbitrage positions. Venture capital funds, which invest in early-stage companies with high growth potential, are also classified as AIFs (Category I). Bonds and stocks are typically considered traditional investments, not AIFs.
