HKSI Paper 4 common mistakes
HKSI Paper 4 · Understand the traps and how to avoid them.
Treating the SFC's licensing regime as a single permission and assuming a Type 1 (dealing in securities) licence also covers advising clients, so the candidate picks the 'obvious' single-licence answer for a scenario describing advice plus dealing.
The regulated activity types are cumulative and separately defined; candidates memorise 'Type 1 = stockbroking' and stop there, so they miss that giving securities advice is Type 4 and asset management is Type 9, and they overlook that a firm can hold multiple licences or that a corporate can be licensed at all.
What to do instead
Build a one-page table of all regulated activity types with a one-line definition and a typical trigger phrase each (e.g., 'advises on securities' = Type 4). Before answering, underline the verbs in the scenario and map each verb to a type, then check whether the question asks what is required, what is permitted, or what is exempt.
Applying the wrong threshold to a supervisory or conduct question, for example assuming the SFC must approve every marketing document, or that a licensed representative needs SFC consent before each client trade.
Candidates conflate the SFC's authorisation powers (which apply to collective investment schemes offered to the public and to listing documents) with universal pre-approval of all communications, and they mix up notification duties with approval duties.
What to do instead
For each document or action in the syllabus, ask three questions in order: is it authorised, is it merely notified, or is it neither? Keep a short list of items requiring SFC authorisation (public offers of unauthorised CIS, listing documents) separate from items requiring only internal approval or notification (suitsability records, changes in substantial shareholders).
Computing a rights issue or open offer outcome using the post-offer share count as the denominator for the theoretical ex-rights price, or ignoring the subscription price when calculating the value of the nil-paid rights.
TERP formulas look like simple weighted averages, so candidates plug in the wrong weights under time pressure; they also forget that the entitlement ratio (e.g., 1 for 4) determines how many new shares attach to each existing share.
What to do instead
Always write the formula explicitly before substituting: TERP = (market value of existing shares + cash raised) / total shares after the issue. Then value a right as TERP minus subscription price. Sanity-check that TERP sits between the cum price and the subscription price; if it does not, you have inverted a weight.
Confusing the roles of sponsor, underwriter, placing agent and financial adviser in a listing scenario, and attributing sponsor due-diligence duties to the underwriter or vice versa.
The titles overlap in practice and candidates answer from general market intuition rather than from the defined responsibilities; sponsor work is about due diligence and ensuring the listing document is accurate, while underwriting is about assuming subscription risk.
What to do instead
Anchor each role to its core economic or legal function: sponsor = due diligence and vetting the issuer for listing; underwriter = takes up unsubscribed shares for a fee; placing agent = markets and allocates to investors; financial adviser = advises on structure and compliance. When a question names a party, ask 'what risk does this party bear?' to identify the role.
Assuming every fund described in a question is authorised by the SFC and therefore subject to the full retail offering rules, including the CIS advertising restrictions.
Most syllabus examples involve SFC-authorised funds, so candidates over-generalise; they miss that private funds, offshore funds and funds sold only to professional investors sit outside the authorisation regime and follow different distribution constraints.
What to do instead
Classify the fund first: authorised retail CIS, unauthorised fund for professional investors only, or a listed vehicle such as an ETF. Then apply the rules for that class. Remember that authorisation is not a recommendation and that unauthorised funds cannot be offered to the Hong Kong public, which drives the marketing answer.
Mixing up the fund structures and their investor consequences, such as treating an open-ended fund company and a unit trust as identical, or assuming an ETF's market price always equals its net asset value.
The distinctions are legal and operational rather than intuitive; candidates learn the acronyms without the underlying mechanics of creation and redemption, which is what keeps an ETF's price close to NAV.
What to do instead
For each structure, memorise three facts: legal form, how units are created and redeemed, and who holds the assets (trustee or custodian). For ETFs, state the arbitrage mechanism that links price to NAV and note that premiums and discounts can still occur, especially in illiquid underlying markets.
Treating a derivative's notional amount as the investor's maximum loss, or assuming a purchased option and a written option have symmetric risk profiles.
Notional values are the most visible number in a derivative scenario, so candidates use them as exposure; the actual risk depends on direction, leverage and whether the position is long or short, and writing an option carries potentially unlimited loss while buying one caps loss at premium.
What to do instead
Before computing anything, label the position: long or short, call or put, buyer or writer. Then state the payoff shape in words (capped loss, unlimited loss, capped gain). Use notional only to size the exposure, never as the loss figure, and check whether margin or collateral changes the answer.
Ignoring the distinction between professional investors and retail clients when answering suitability or marketing questions, and applying retail protections to a professional-investor scenario.
Candidates treat 'professional investor' as a vague label rather than a defined category with specific thresholds and consequences for disclosure, suitability and marketing; they also forget that a client can opt up or be treated differently for different products.
What to do instead
Memorise the professional investor definition and its practical effects: reduced disclosure and suitability obligations in defined circumstances, but conduct rules on honesty and fair dealing still apply. In every scenario, first identify the client category, then ask which obligations still bite.
Answering suitability questions by checking only whether the product matches the client's stated risk appetite, without considering the client's financial situation, investment objectives, knowledge and experience, or the concentration of the resulting portfolio.
Risk rating is the easiest attribute to compare, so candidates stop there; they also overlook that suitability is a process obligation, including knowing the client and keeping records, not a single matching test.
What to do instead
Use a fixed four-part checklist for every suitability question: knowledge and experience, financial situation including ability to bear losses, investment objectives and horizon, and risk tolerance. Then check the recommendation against all four and against portfolio concentration, and confirm the record-keeping step.
Selecting an answer that describes the commercially convenient action (execute the client's instruction immediately, or accept a gift to maintain the relationship) rather than the conduct rule outcome, especially on conflicts of interest and personal account dealing.
The exam tests standards, not commercial pragmatism; candidates default to what a salesperson would do, and they underestimate how strictly conflicts, gifts and personal account dealing are regulated, including the need for prior approval and disclosure.
What to do instead
For any conduct scenario, apply a hierarchy: client interest first, then disclosure, then approval, then documentation. If an answer involves acting before disclosing or obtaining consent, treat it as suspect. Practise identifying the specific rule triggered (conflict of interest, inducement, personal account dealing) before choosing the response.
