The composite starts from a weighted base of four hard-data dimensions (below), each scored 0–100 from public data. We publish the exact weights so it is reproducible, not a black box. Then a short-board gate mixes in the weakest of the three core criteria (margin, sponsor, industry), so a single hot dimension cannot carry a stock with a real weakness to the top rank.
Margin heat (30%) reads the disclosed broker margin oversubscription; high demand often maps to a higher grey-market premium probability. Industry theme (30%) rewards in-favour sectors and strong cornerstones (题材性感). Sponsor track record (25%) proxies fundamentals via the lead sponsor tier. Entry friendliness (15%) favours a low entry fee. The tiers then read: 王者 (King) = strong on all three core criteria; 星耀 (Star) = strong overall but with one short board; 钻石 (Diamond) and below = a clear deficiency. Community sentiment and IPO environment are shown as context bars only, never fabricated when data is missing.
