How to Evaluate an IPO Before Applying
Before investing in any open IPO, consider these factors:
-
Company fundamentals: Review revenue, profitability, debt and cash flow.
-
Valuation: Compare the issue valuation with listed peers where appropriate.
-
IPO structure: Understand the difference between a fresh issue and an offer for sale.
-
Subscription data: Track qualified institutional, non-institutional and retail demand as it becomes available.
-
GMP trends: Use GMP only as an unofficial sentiment indicator, not as a reliable forecast.
-
Risk factors: Read the RHP, including litigation, customer concentration, industry risks and the proposed use of funds.

October 15 brings several IPO opportunities across the mainboard and SME markets. Bonfiglioli Transmissions, Tonbo Imaging India, Zetwerk Manufacturing Businesses, Sahajanand Medical Technologies and Shellz India are opening today, while HD Fire Protect and Vaibhav Vyapaar are scheduled to close.
