About 15 SMEs will tap the Indian stock market with their initial public offerings (IPOs) and mobilize over Rs 3.84 billion this week, ending September 30. Meanwhile, big Indian companies are reluctant to tap the market and are waiting for clarity to emerge on the current economic uncertainty before going public. Out of the proposed 15 IPOs, two will be listed on NSE’s SME platform Emerge, while 13 will be listed on the Bombay SME exchange. The buoyancy in India’s SME IPO market is because of the encouraging response in terms of oversubscription received by all 35 SME IPOs this year.
