Investing in the Indian stock market requires understanding the different types of IPOs. IPOs, or Initial Public Offerings, allow companies to raise capital from the public by listing their shares on stock exchanges. In India, IPOs are broadly categorized into SME (Small and Medium Enterprise) IPOs and Mainboard IPOs. Both offer unique investment opportunities, but the risks, benefits, and regulatory frameworks differ significantly. This guide will help IPO investors make informed choices.
