ROC-A Exam common mistakes
ROC-A Exam · Understand the traps and how to avoid them.
Treating the exchange's rulebook and the regulator's conduct rules as one interchangeable rule set, so answers cite the wrong source of obligation for a given behaviour.
Candidates study both documents together and memorise outcomes without recording which body imposes the duty; the two overlap in subject matter but differ in scope, enforcement route, and remedies.
What to do instead
Build a two-column log for each topic (order handling, disclosure, market abuse) recording the exchange rule reference and the statutory/regulatory provision side by side, and before answering ask which type of obligation the stem describes: membership/listing obligation or conduct-of-business obligation.
Assuming a market segment's trading mechanism (call auction, continuous session, circuit breakers, price limits) is uniform across all segments, and applying the main-board mechanics to a segment with different rules.
Most study time is spent on the largest, most familiar segment, and candidates generalise from it rather than checking whether a smaller segment has distinct opening procedures, volatility controls, or eligibility criteria.
What to do instead
Create a one-page matrix of segments with columns for trading method, session times, price limit or volatility control, and investor eligibility, and rehearse it until each cell can be recalled without prompts.
Confusing the settlement cycle and settlement obligations of different instrument types, or assuming that a trade executed on one day settles a fixed number of days later regardless of instrument or market.
Settlement conventions are learned as a single number, and the exceptions for particular products or cross-border trades are treated as trivia rather than as examinable distinctions.
What to do instead
Maintain a settlement table by instrument class showing the standard cycle, the trade-date convention, and any exception, and practise questions by first identifying the instrument class before calculating any date.
Mixing up order types and their execution priority, for example treating a market order as price-protected or assuming a limit order always fills at the limit price rather than at the best available price within the limit.
Order terminology is learned by label rather than by the execution logic behind each type, so the interaction between price, time priority, and protection is not internalised.
What to do instead
For each order type write a single sentence stating what price it can execute at, when it can execute, and what happens if it cannot; then work through short scenarios where two order types compete in the same book and state which fills first and at what price.
Confusing yield measures, such as quoting a bond's coupon rate when the question asks for yield to maturity, or ignoring the effect of reinvestment assumptions and accrued interest on the price paid.
Coupon, current yield, and yield to maturity are studied close together and share vocabulary, and candidates answer from the number most visible in the stem instead of from the definition the question requires.
What to do instead
Write out the definition and formula for each yield measure and the assumption each embeds, then practise converting one into another for the same bond and reconciling the dirty price to the clean price plus accrued interest.
Treating money market instruments as equivalent to short bonds, ignoring the discount-basis quotation convention and the difference between discount rate and true yield.
The arithmetic looks familiar, so candidates apply bond yield logic to treasury bills and commercial paper and overlook that the quoted rate is applied to face value rather than to the invested amount.
What to do instead
Drill the discount-price and discount-rate formulas separately from bond pricing, always labelling which base (face value or price) the rate is applied to, and convert a quoted discount rate into a holding-period return to confirm the direction of the difference.
Confusing the rights and obligations of the long and short parties in forwards, futures, and options, for example stating that a futures buyer posts variation margin only when losing, or that an option writer chooses whether to be exercised.
The products are learned as a family of similar contracts, and the asymmetry of options and the daily mark-to-market of futures are not separated into distinct mental models.
What to do instead
For each product draw a two-row table for long and short with columns for premium paid or received, margin or collateral obligation, maximum gain and loss, and who holds the exercise right; reconstruct the table from memory before attempting calculation questions.
Answering structured product questions from the headline coupon without identifying the embedded derivative, the capital protection level, and the conditions that reduce or eliminate the payout.
Marketing-style descriptions emphasise the coupon, and candidates accept that framing instead of decomposing the payoff into its components and testing the downside scenario.
What to do instead
For every structured product, restate it as a bond plus or minus specific options, then state the payoff in three scenarios (favourable, flat, adverse) and identify who bears which risk; answer only after the adverse scenario is written down.
Treating best execution as a single obligation to obtain the lowest price, rather than a duty to take all sufficient steps considering price, cost, speed, likelihood of execution and settlement, and the client's specific instructions.
The phrase 'best execution' invites a price-only reading, and candidates overlook that client instructions can displace the firm's execution judgement and that the standard is reasonable steps rather than a guaranteed outcome.
What to do instead
Memorise the execution factors as a checklist and apply it to each scenario, explicitly noting when a specific client instruction narrows the obligation; also practise distinguishing the firm's duty from the client's own investment decision.
Failing to separate a firm's own-account activity from client-facing activity when answering conflict-of-interest and market-abuse questions, so the answer applies the wrong standard or misses the disclosure or wall-crossing requirement.
The same transaction can be described from either perspective, and candidates answer the general ethics question without first classifying the capacity in which the firm is acting and what information it holds.
What to do instead
Before answering, state in one line the firm's capacity (agent, principal, or both) and the material non-public information held, if any; then apply the corresponding obligation, checking whether a conflict must be managed, disclosed, or declined, and whether information barriers or a permitted crossing apply.
