How do PRIM, mutual fund & PMS investment routes differ?

Mutual funds allow investors to invest money in professionally managed funds with a low entry amount. PRIM, a new investment route introduced by SEBI, requires a minimum ₹ 25-lakh investment and allows professionals to select mutual funds, ETFs, index funds and SIFs. Meanwhile, PMS requires at least ₹50-lakh investment with managers directly buying stocks and other securities for investors.
