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 TIANYU SEMI?
Public allotment filings put the official one-lot rate at 10.0%, versus this site's pre-allotment model estimate of 22.0%. It is an observation for a 1-lot application, not a guaranteed result.
What is the difference between A-tail and B-head for TIANYU SEMI?
Based on the prospectus's legal application tiers, A-tail is 1,600 lots and B-head is 1,800 lots, representing about HK$4.6M and HK$5.2M of application principal. Official average allotment was 15.19 lots and 28.8 lots, versus pre-allotment model estimates of 4.93 lots and 18.97 lots. Pool A and Pool B are allocated separately, so application size alone does not show capital efficiency.
Can the grey-market price of TIANYU SEMI be treated as the listing price?
The compiled grey-market observation is about -14.5%, versus -30.2% on the listing day. Grey-market prints are pre-listing sentiment from public sources, not the official opening price.
Why does TIANYU SEMI have three reference ratings?
The current status is "Listed", so start with the post-grey 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.
