Sanjay bid for a highly anticipated IPO lot. The retail category subscription rate was reported at 8.5 times oversubscribed. Sanjay checked his allotment chances.

His probability of receiving a lot allotment was 11.76% due to the draw of lots lottery system. Understanding this, he applied across multiple accounts.

Frequently Asked Questions

How is IPO allotment decided in oversubscribed issues?

When the retail portion of an IPO is oversubscribed, the allotment is decided via a computerized draw of lots (a lottery system) supervised by the exchange registrar.

Does applying for multiple lots increase my chances?

No. In the retail category, applying for 10 lots from a single PAN card gives you the exact same probability of allotment as applying for 1 lot.

How can I increase my IPO allotment chances?

The only mathematical way to increase your chances is to apply for single lots across multiple separate demat accounts registered under the names of different family members.
