Subscription Data
During the IPO subscription period, real-time data reveals market demand. Understanding this data helps you gauge interest and adjust expectations.
Subscription data is available throughout the IPO period on exchange websites. It updates multiple times daily.
Understanding Subscription
Subscription = Total Demand / Shares Offered
| Subscription | Meaning |
|---|---|
| 0.5x | Only 50% of shares applied for |
| 1x | Exactly subscribed (demand = supply) |
| 2x | Double the demand vs supply |
| 10x | 10 times oversubscribed |
| 100x+ | Extreme demand |
Category-wise Subscription
IPO shares are allocated across categories:
| Category | Who | Share Reserved |
|---|---|---|
| QIB | Mutual funds, FIIs, banks | Up to 50% |
| NII (HNI) | Investors above ₹2L | 15% |
| Retail (RII) | Investors up to ₹2L | 35% |
| Employees | Company staff | Varies |
Each category is subscribed separately.
QIB subscription is most informative – professional investors have done their analysis. Strong QIB demand is a positive signal.
What High Subscription Means
For Allotment
| Your Category | If 10x Subscribed | Your Chances |
|---|---|---|
| Retail | Lottery for 1 lot | 10% chance of getting 1 lot |
| NII | Proportionate | Get 10% of what you applied |
| QIB | Proportionate | Get 10% of what they bid |
For Listing
High subscription often correlates with:
- Strong listing (premium to issue price)
- Initial buying interest
- Market buzz
But not always – some oversubscribed IPOs list below issue price.
What Low Subscription Means
| Subscription | Signal |
|---|---|
| Under 1x overall | Weak demand, avoid |
| 1-2x | Tepid, be cautious |
| High in one category only | Selective interest |
If QIB portion is undersubscribed, it's a major red flag. Professional investors aren't interested.
Daily Subscription Patterns
Typical pattern:
- Day 1: Slow start (20-30% of final)
- Day 2: Picks up (50-70%)
- Day 3: Rush in final hours (highest activity)
Don't panic based on Day 1 numbers.
Reading the Data
Strong IPO Signs
| Indicator | Reading |
|---|---|
| Growing day by day | Building momentum |
Weak IPO Signs
| Indicator | Reading |
|---|---|
| QIB under 1x | Professionals not interested |
| Overall under 1x | Risk of undersubscription |
| Retail only high | Retail mania, no institutional backing |
| Heavy last-day bidding | Desperation applications |
The Grey Market Premium (GMP)
Unofficial indicator of expected listing gain:
GMP = Expected listing price - Issue price
Example:
- Issue price: ₹100
- GMP: ₹30
- Expected listing: ₹130
GMP is unofficial and can be manipulated. Use it as one data point, not the primary decision factor.
Bidding Strategy
Based on subscription data:
| If | Strategy |
|---|---|
| Strong IPO (over 5x expected) | Apply early for better allotment chance |
| Moderate IPO (2-5x) | Apply by Day 2 |
| Weak IPO (under 2x) | Reconsider applying |
