Buying shares in an IPO is exciting. It can be a good way to grow your money. But many people have trouble getting the shares. Popular IPOs go fast. Even if you have tried before, you may not get any shares.
The good news is that you can increase your chances with this if you follow some easy and proven steps. In this guide, we will talk about the top 5 investment rules for IPO. We make it simple to read, with tips that anyone can use. It does not matter if you are new or have some practice.

1. Apply in the Retail Category Wisely – One of the Top 5 Investment Rules
In India, most IPOs set aside 35% of their shares for retail investors. If you apply for shares in this group, your chance to get shares will be higher than for people in other groups, like non-institutional or QIB.
Tips:
- Go for the minimum lot size first. In IPOs where there are more people who want shares than the number of shares available, who gets shares is decided by how many they ask for. If you ask for fewer shares, you have a better chance to get some shares.
- Do not send in more than one application with the same PAN. If you do this, you might be left out.
- For example, if a retail IPO lot size is 100 shares and you go for only 1 or 2 lots instead of 5 to 10, you have a higher chance to get at least one lot.
2. Use Multiple Demat Accounts Legally – A Key Investment Rule
If your family has more than one Demat account, each person can use their own account to apply for the same IPO. This can help you and your family get a better shot. There is a chance that at least one account will get shares.
Key Rules:
- You can only use the accounts from your close family, like your spouse, kids, or parents.
- Make sure every account has KYC done and is linked to a working bank account.
- For example, if your parents and spouse each get one lot in an IPO, you have more chances than if you just use one account.
3. Use ASBA or UPI for Smooth Processing
You have to use the Application Supported by Blocked Amount (ASBA). Or you can use the UPI payment method when you want to apply for an IPO.
Why it matters:
- The money you have stays in the bank. It does not go out until you get shares.
- You get your money back at once if you do not get shares.
- This way has less mistakes than when you use net banking or cheques.
Pro Tip: You should check your UPI ID or ASBA details two times. This lets your form be correct. A small error can keep your form from being accepted.

4. Apply at the Right Time Top 5 Investment Rules
Sometimes, timing changes how things happen. You can see this in IPOs when many people want to buy shares.
Best Practices:
- Send in your application during the first two or three days when the IPO starts.
- Do not wait until the last minute to apply. A lot of people go on the trading websites at that time, and there can be delays.
- If you apply early, your application will usually be handled quicker. You can get a good chance to get shares if not many people are looking for them in this IPO.
Example: In the Canara HSBC Life IPO 2025, people who put in their application early did not have to wait a long time. Each one got their amount sorted out with no problem at all.
5. Check Eligibility and Documentation Carefully
Many applications do not get approved. This could be because the paperwork is not complete. There can also be mistakes in some details.
Checklist Before Applying: Top 5 Investment Rules
- The PAN needs to be the same as what is on your Demat.
- Your bank must work right. It should be joined with ASBA or UPI.
- Your KYC must be current.
