What Abhishek Kumar said
How is the opening price of a newly listed IPO actually decided?
The exchanges discover it in a pre-open session on listing day, in a ten-minute window from 9:45 AM, at the price where the largest number of shares can be traded. Only limit orders are accepted, and no price bands apply at first. If the equilibrium prices on the two main exchanges are apart by more than the allowed band, a common price is worked out as a volume-weighted average. So the listing price shows the genuine demand that came in through orders during that window.
Does the grey market premium decide the listing price?
No. The exchange calculates the listing price only from the actual limit orders placed in the pre-open session. The grey market premium plays no official part in discovering the price; it is unregulated speculation. It does influence sentiment, though, and that sentiment affects what orders investors put in, which is how it can indirectly affect where a stock opens.
Does heavy oversubscription mean the IPO will list strongly?
Not necessarily. Oversubscription can mislead, because many HNIs borrow to fund their bids without any real long-term interest, and that leveraged demand mostly does not show up on listing day. If institutional demand is weak, pressure in the pre-open session stays low and the stock can list weak. Anchor investors and QIBs matter more, through binding orders in that session. Aggressive pricing that leaves no valuation cushion can also cause a discounted listing despite strong subscription.
What mistakes do retail investors make around IPO listings?
The most common mistake I see is getting carried away by the grey market premium and the subscription numbers. Investors forget that the premium is unregulated speculation and that subscription figures can include leveraged HNI bids. Many also follow the hype instead of checking the company's fundamentals, and assume that institutional interest always means a short-term profit.
In our words, from what he said in the piece. General information, not personal advice.
