1. Background
The Securities and Futures (Short Position Reporting) Rules (Cap. 571AJ) were made by the SFC under sections 397(1) and (2) of the Securities and Futures Ordinance (Cap. 571) and took effect on 18 June 2012. The regime improves market transparency on short positions — the SFC publishes the aggregated short position of each designated share for public viewing on its website.
Do not confuse it with the short-selling restrictions (Cap. 571R — delivery cover, designated-securities-only short selling). Cap. 571AJ governs reporting: lawfully held short positions that cross the threshold must be reported.
2. Who reports? How is the threshold computed?
Section 3: any person (not limited to licensed corporations) whose net short position in designated shares reaches the floor holds a "reportable short position":
- Ordinary designated shares — the lower of:
- HK$30 million; or
- 0.02% of the total value of the corporation's issued designated shares
- Designated shares that are collective investment scheme (CIS) interests — fixed at HK$30 million
The net-position formula (s.3(2)(a)):
Longs net off shorts first. Example: a small-cap where 0.02% of issued value comes to HK$8M — the threshold is HK$8M, not HK$30M — small caps trip the line easily.
3. When to report?
Reporting day: positions held at the close of each Friday. If HKEX is closed on Friday, use the preceding trading day (s.4(1)).
Deadline: within 2 business days after the reporting day (s.4(2)), via the SFC's designated electronic system (WINGS).
Daily-reporting notice: if the SFC gazettes a notice for financial-stability reasons (s.7), reporting shifts to every trading day, due within 1 business day. This mechanism has been used during severe market volatility.
After the deadline, the SFC publishes aggregated short positions as soon as practicable (s.6) — the data is public, so counterparties can see how large a short has built up in a stock.
4. Which shares? — "Designated shares"
Not every HK stock is reportable. Schedule 1 defines designated shares as "designated securities" determined under HKEX rules — the same source list as for short-selling designated securities. HKEX updates the list regularly; it broadly covers Main Board mid/large caps and eligible ETFs/REITs.
5. Special cases: trusts and fund managers
- Trustees: for reportable short positions held on trust, the trustee reports (s.4(5)).
- Fund managers: under the SFC's Guidance Note on Short Position Reporting, the person exercising control is not necessarily the reporting party — where a fund manager exercises discretion over a corporate fund's positions, the reporting duty rests with the fund itself (the trustee). The Note recommends judging unit trusts on their overall circumstances rather than tracking holder by holder.
- Aggregation: short positions across multiple books/units of the same group should be aggregated when testing the threshold.
6. What if you don't report? — real enforcement
The SFC has consistently pursued short-position-reporting failures. Two public disciplinary actions:
Reprimanded and fined by the SFC for short-position-reporting failures. Official press release ↗
Likewise reprimanded and fined for short-position-reporting failures. Official press release ↗
Beyond reporting failures, unlawful short selling (breaching Cap. 571R / s.170 SFO) is a criminal offence — the SFC has prosecuted retail investors, brokers and former responsible officers over the years; in 2024 the first criminal conviction for securities fraud committed through unlawful short selling was sentenced to imprisonment.
7. Compliance checklist
- Position system computes the net short value of each designated share daily — (A−B)×C
- Run the threshold test before Friday close: min(HK$30M, 0.02%×market value)
- On breach → report via WINGS within T+2 business days
- Trust structures: confirm the trustee's reporting arrangement is documented
- Multiple books across the group: aggregate — don't under-report by counting book by book
- Keep filing records and position snapshots for enforcement queries
- Sync HKEX's designated-securities list updates

9. FAQ
Do retail investors have to report?
The rules apply to anyone — but retail short positions rarely reach HK$30M, so in practice it is mainly an institutional matter. Unlawful short selling, however, is prosecuted even against individuals — the SFC has convicted multiple individual investors.
If Friday is a holiday, which day is the reporting day?
Roll back to the preceding HKEX trading day (s.4(1)(b)) — e.g. Thursday. The deadline is unchanged: 2 business days after that day.
How do longs offset shorts?
Long positions held by the same person net off first (A−B). But note: shorts built through borrowed shares, or positions of different legal entities, cannot be netted casually — for specific scenarios consult a lawyer or compliance adviser.
Late filing or omission — criminal liability?
Cap. 571AJ is a reporting regime; breach can lead to disciplinary action — reprimand and fines (see Talent Capital and Zhongyuan Capital above). Submitting false information may separately constitute the offence of providing false or misleading information under s.384 SFO.
