HNI IPO Bidding Strategies: Small HNI (sHNI) vs Big HNI (bHNI) Quota Math & Profitability

1. Understanding the Non-Institutional Investor (NII/HNI) Quota

SEBI reserves 15% of the total IPO issue size for Non-Institutional Investors (NII), defined as individual investors, NRIs, HUFs, companies, and trusts applying for more than ₹2,00,000.

To ensure equitable distribution, SEBI subdivided the NII quota into two sub-categories:

---

2. Critical Rule: No Cut-Off Price for HNIs

Unlike retail investors who can simply tick the "Cut-Off" box, HNI bids with "Cut-Off" selected are rejected automatically.

HNIs must explicitly enter the Cap Price (upper price band) in their ASBA form. Bidding even 1 Rupee below the upper band in a high-demand IPO guarantees non-allotment.

3. The Math of NBFC IPO Funding & Breakeven

Many HNIs borrow capital from Non-Banking Financial Companies (NBFCs) to bid large amounts:

Loan Duration: Typically 5–7 days under T+3.

Interest Rate: 9.5% to 12% p.a.

Breakeven Formula:

$$\text{Breakeven GMP (\%)} = \frac{\text{Total Interest Paid} + \text{Processing Fees}}{\text{Allotted Value}} \times 100$$
