We have read enough on the topic.A proposal from SEBI was to introduce a circuit limit on first few days of listing to try to contain the problem. I personally do not think it will be a big deterrant for the IPO scams that are abound. The only benefit will be that a genuine investor will not lose all his money on Day 1 and instead only lose 10% or so. He might get a chance to get out on subsequent days. A 200-300 page+ prospectus is prepared, lots of money spent to disclose information to the investors.... But in reality, all this is eye wash. Someone in the whole process knows what truly is the value of the company and its shares. The listing day trading is just a process to bring the true value of the company at the cost of genuine investors. Riskpro's analysis of the recent IPOs have indicated that most of the hoor stories in IPO are for those companies which have been rated below average as part of the IPO ratings. This means that manipulation is easiest or intended when the fundamentals of the company are weak. A further, though very remote possibility or inference from this observation could be that weak companies who are trying to get listed and run businesses on public money are targets for volatile trading, maybe because their issue size is small and easy to manipulate on Day 1. Riskpro is working on this angle and will provide more updates soon. Disclaimer: The above inferences and opinions are possibilities that could exist in the IPO scams. There are no facts yet to prove these points.
