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 LONGSYS?
Public allotment filings put the official one-lot rate at 2.9%, versus this site's pre-allotment model estimate of 24.9%. It is an observation for a 1-lot application, not a guaranteed result.
What is the difference between A-tail and B-head for LONGSYS?
Based on the prospectus's legal application tiers, A-tail is 400 lots and B-head is 600 lots, representing about HK$4.7M and HK$7.1M of application principal. Official average allotment was 10.56 lots and 13.96 lots, versus pre-allotment model estimates of 3.88 lots and 10.27 lots. Pool A and Pool B are allocated separately, so application size alone does not show capital efficiency.
Can the grey-market price of LONGSYS be treated as the listing price?
The compiled grey-market observation is about -0.5%, versus -1.3% on the listing day. Grey-market prints are pre-listing sentiment from public sources, not the official opening price.
Why does LONGSYS 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.
