Not every Hong Kong–listed holding is financeable, and the ones that are are not all financeable on the same terms. Before a rate is quoted or a tenor discussed, a lender is running a single, unglamorous screen: can this collateral be realised, in size, without moving the price against itself?
That question decomposes into three measurable properties of the underlying stock — free float, average daily traded value, and shareholder concentration — and a handful of qualitative overlays. Together they determine whether a position is eligible at all, and if so, the indicative loan-to-value band the position can support. It is worth being explicit at the outset: there is no published rate or LTV grid on this site, and there is no universal number. Ratios are indicative, vary materially with the specific ticker, and are issued only after a review of the position. What follows is the framework a lender applies, not a schedule of promises.
Free float: what can actually be sold
Free float is the portion of a company's shares genuinely available to trade in the open market — total shares in issue, less the stakes that are effectively locked up: the controlling shareholder's block, strategic corporate holdings, and other long-term insider positions. It is the number that matters for collateral, because it is the pool into which a pledged position would have to be sold if a facility were ever enforced.
A stock can have a large market capitalisation and a thin free float at the same time — a common pattern among founder-controlled Hong Kong issuers and family conglomerates. Headline market cap flatters the position; free float tells the lender what is real. A deep free float relative to the pledged position supports a higher indicative LTV, because the collateral can be liquidated in an orderly way. A thin free float compresses the band, because any forced sale would represent a meaningful share of the tradeable pool and would move the price. The concept is close to the free-float methodology HKEX and index providers use to weight constituents; a lender applies the same logic for the opposite purpose.
Average daily traded value: how fast, at what cost
Average daily traded value (ADTV) — how much of the stock changes hands each day, measured in HKD rather than share count — is the second gate, and often the binding one. Free float tells the lender the size of the pool; ADTV tells the lender how quickly the pool refreshes. The relevant figure is the pledged position expressed as a multiple of ADTV: a position equal to a fraction of one day's turnover is trivial to exit; a position equal to many days' turnover is not, because selling it compresses the price and the sale itself becomes the news.
This is why two shareholders with identically-sized HKD positions in different names can receive materially different indicative terms. In a liquid large-cap index constituent, the position may be a small multiple of ADTV and support a comfortable band. In a mid- or small-cap where the same HKD position represents weeks of average turnover, the indicative LTV falls sharply, the tenor may shorten, and the recourse profile is scrutinised — because the lender's exit, in the tail scenario, is slow and expensive. A rational lender prices the difficulty of the exit, not the current screen price.
Concentration: the position behind the position
Shareholder concentration is the third variable, and it cuts in two directions at once. On one hand, concentrated founder and family holdings are precisely the positions this market exists to serve — they are large, long-held, and often the entire point of a stock loan. On the other, high concentration is exactly what makes a stock harder to finance, because a dominant holder is, by definition, most of what is not free float, and because the enforcement of a facility over a controlling stake carries consequences that a portfolio position does not.
Two of those consequences are regulatory. A change in a substantial shareholder's interest engages the SFO Part XV Disclosure of Interests regime; and a sale or acquisition that crosses certain levels can engage the SFC Codes on Takeovers and Mergers. Neither is a reason a concentrated position cannot be financed — they are structuring inputs, addressed at the outset with the borrower's own Hong Kong counsel. But they mean a highly concentrated stake is never assessed on liquidity metrics alone. The disclosure and Takeovers analysis sits alongside the free-float and ADTV analysis, and all of it feeds the terms.
The qualitative overlays
On top of the three core metrics sit the overlays that move a position within its band, or occasionally out of eligibility altogether. Price volatility widens the haircut a lender takes: a stable large-cap and a volatile growth name with the same liquidity are not financed identically. Sector carries its own dynamics — a pre-revenue Chapter 18A biotech, whose value can move by large multiples on a single regulatory milestone, is financed far more conservatively than a long-listed property or financial holding, and often at roughly half the band a comparable position size in a stable sector might support. Corporate-action and event risk — pending results, dividend cycles, lock-ups, rights issues, suspension history — is examined, because each affects when and how the collateral can be dealt with. And regulatory standing, including any history of trading suspension or investigation, is a gating factor in its own right.
Both Main Board and selected GEM-listed equities can be considered, including Chapter 18A issuers, with terms calibrated to the specific risk profile of the name. Eligibility is genuinely case by case; the screen described here is how a serious lender forms a view, not a formula that outputs a number.
The right question is never simply can this stock be pledged. It is at what level, on what tenor, and with what recourse — and the answer lives in the free float, the traded value, and the concentration of the specific name, reviewed one ticker at a time.
