How to read this page

These answers combine this IPO’s published figures with clearly labeled model estimates. They explain how to read the modules above and are not investment advice.

What is the one-lot allotment rate for HEMAY PHARMA-B?

The IPO is still in its offer period, so there is no official one-lot rate yet. This site's current model estimate is about 21.2%; the company allotment announcement is final.

What is the difference between A-tail and B-head for HEMAY PHARMA-B?

Based on the prospectus's legal application tiers, A-tail is 2,000 lots and B-head is 3,000 lots, representing about HK$3.8M and HK$5.7M of application principal. Pool A and Pool B are allocated separately, so application size alone does not show capital efficiency.

Can the grey-market price of HEMAY PHARMA-B be treated as the listing price?

Grey-market trading is dated Nov 6. Before that session there is no print to cite. Even after quotes appear, they are not the official listing price.

Why does HEMAY PHARMA-B have three reference ratings?

The current status is "Open", so start with the subscription section. Subscription, pre-grey and post-grey each use only the public information available at that point, so the score can change. Labels are high attention / neutral / caution only — informational comparison, not a buy or subscribe call.
