Allotment Overview Calculated

Total Subscription Fees vs Public Offering Raise Amount

Subscription Tier Analysis Model prediction

Expected Lots Allotted by Subscription Tier

Pool A applications , Pool B applications . Expected lots allotted = "Approximate percentage of total shares applied for" as stated in the allotment announcement × shares applied ÷ lot size, taken directly from the announcement.

Capital Efficiency by Subscription Tier

Capital efficiency = Expected shares allotted ÷ shares applied × 100, i.e. the original "Approximate percentage of total shares applied for" value from the allotment announcement. The fewer shares applied for, the higher the capital efficiency.

Applicant Distribution by Subscription Tier

The vertical axis uses a logarithmic scale to better observe distribution differences across tiers of varying magnitudes. All four charts share the same x-axis; hover tooltips are synchronized.

Subscription Fee ÷ Allotted Market Value by Tier

Allotted market value = valid applicants × shares applied × (percentage applied for ÷ 100) × offer price; total handling fees = valid applicants × HKD 100; ratio = total fees ÷ allotted market value × 100%. Lower tiers have disproportionately high ratios due to very small allotments; ratios stabilize at higher tiers.

The following content is generated by an AI model based on historical IPO data. It does NOT constitute investment advice, solicitation, or recommendation. Past subscription patterns and post-listing performance do not guarantee future results. Data may contain inaccuracies — always verify against official HKEX filings and prospectuses before making any investment decision.

Market Sentiment

The IPO of 瑞博生物-B saw overwhelming retail demand with an oversubscription ratio of 101.06 times, resulting in a low hit rate of just 12.55%. This level of enthusiasm is typical for high-profile biotech listings under Chapter 18A, reflecting strong market appetite despite no clawback mechanism. (This is AI-generated commentary based on historical data. Past patterns do not guarantee future outcomes. Not financial advice.)

Tier Analysis

The allocation at the top of the retail tier (甲尾) yielded an expected 0.2614 lots for an application of 80,000 lots, slightly higher than the 0.2275 lots expected for the bottom of the HKSFC tier (乙头) with 90,000 lots applied. This is unusual as B-head applicants typically receive a proportionally higher allocation, but here the marginal benefit of moving to the B tier is negligible, making the A-tail unexpectedly efficient relative to broker costs. (This is AI-generated commentary based on historical data. Broker fee structures vary and actual costs may differ. Not financial advice.)

Demographics

No detailed demographic breakdown was available in the filing, with reported mainland and Hong Kong participant percentages at zero, likely indicating that the data was not disclosed or not applicable. In practice, biotech IPOs often draw significant interest from mainland Chinese investors despite Hong Kong-centric subscription channels. (This is AI-generated commentary based on historical data. Data may contain errors or omissions from source documents. Verify against official HKEX filings. Not financial advice.)
