 SEBI released trading controls  for Listing day IPO price fluctuations.

1.  I have earlier commented on IPO Listing day volatility.
2. SEBI has responded with lot of sensible measures to tame down the Volatility .
3. The detailed  sebi circulars relating to this.
4. A good paper on Call auctions by a respected financial economist Dr Susan Thomas
5. Whether this affects price discovery, liquidity and Broker funding for IPOs remains to be seen.
6. Research paper on IPO Volatility. The abstract seems interesting at Indian Journal of Finance
