Logo51World Allotment Prediction Matrix

Rows are subscription tiers, columns are different oversubscription ratios, values are expected allotment lots; green indicates expected ≥1 lot. Non-preset multiples are interpolated from the nearest grid points.

Offering Mechanism

18C

HKEX Listing Rule Chapter 18C for specialist technology companies. Mechanisms A and B do not apply. Initial allocation 5%, with clawback: 10x to below 50x → 10%, 50x or above → 20%. At least 50% of total offering shares must be taken up by independent pricing investors in the placing tranche.

Allocation Strategy Coefficient α

α is the issuer's allocation preference coefficient, describing the issuer's allocation tendency across subscription sizes. α ranges [0, 1].

  • α → 0: Per-capita allocation — regardless of lots subscribed, every allottee receives the same number of shares. More favorable to retail (small) applications.
  • α → 1: Proportional allocation — allotted shares are proportional to lots subscribed. More favorable to large applications.
  • Historical actual α range (P10–P90): Pool A 0.3–0.9, Pool B 0.4–1.0. α varies widely across IPOs, reflecting each issuer's allocation strategy.
Allotment Rate Definition

The "allotment rate" on this page follows the exact HKEX allotment results announcement definition: Allotment rate = total shares allotted to the tier ÷ total valid shares applied in the tier × 100%. This is the official HKEX standard and is fundamentally different from other definitions used elsewhere (e.g. "ratio of applicants who got allotted").

Expected Allotment Lots

Expected allotment lots = total shares allotted to the tier ÷ lot size ÷ number of applicants in the tier

Example: a tier with 50,000 total allotted shares, 100 shares per lot, and 500 applicants → expected allotment lots = 50,000 ÷ 100 ÷ 500 = 1.0 lots.

About this page

This page shows expected-lot forecasts for 51World (06651): expected hit rate based on similar-IPO matching and Pool A/B capital-efficiency comparison.
The default oversubscription multiple follows the chain recent first-day return → participant count → average lots per participant → multiple, i.e. multiple = participants × average lots ÷ public-offer lots; participant count and average lots are anchored on the recent IPO median and adjusted by offering size, A+H status, H-share premium/discount, industry, concurrent IPOs, sponsor track record and recent HSI moves.
Early in the subscription window the default multiple relies on the model; as subscription progresses it blends in the margin multiple; near the deadline (roughly 90% through) it follows the margin multiple.
Hit-rate forecasts fit 22087 allotment-tier records across 592 historical IPOs via regression and KNN similar-IPO matching, estimating expected lots per application tier and applying the allocation-strategy coefficient α (equal-per-person to proportional allocation). You can override the oversubscription multiple and the allocation-method α right on the page, replacing cibo's defaults to see expected lots under your own scenario. How allotment rates and clawback work is explained in How Hong Kong IPO Allotment Rates Work.
Data sources: HKEXnews public-offer allotment result announcements, prospectuses and FINI announcements; margin data (margin multiple, TradeGo forecast multiple and broker breakdown) comes from 捷利交易宝 (TradeGo), where the margin multiple covers only reporting brokers and the TradeGo forecast multiple is a full-market extrapolation.
The margin multiple updates intraday in real time; the hit-rate model is refreshed as new IPO allotment data is ingested.
