SEC CO/AP common mistakes
SEC CO/AP · Understand the traps and how to avoid them.
Treating the options disclosure document (ODD) delivery requirement as satisfied by handing the customer the options risk disclosure booklet only once at account opening, without documenting delivery or providing it before the first transaction in each new account.
Candidates memorize 'deliver the ODD at account approval' and lose track of the timing rule that the ODD must be delivered at or before the time the account is approved for options trading, and the firm must maintain records of delivery; they also conflate the ODD with the customer agreement and the new account form.
What to do instead
Build a one-page timeline of the options account-opening sequence: customer application, ODD delivery, principal approval (Registered Options Principal), and first trade. For each step, note the document delivered and the record the firm must retain. Practice questions that ask 'when must X be delivered relative to Y' by writing the sequence from memory before reading the answer choices.
Computing intrinsic value and time value of an option using the wrong reference price (for example, using the strike plus premium, or using the underlying's price at expiration rather than at the valuation date).
Candidates conflate 'value at expiration' with 'value today' and mix up the premium paid with the strike. They also forget that intrinsic value can never be negative and that time value equals premium minus intrinsic value, which is zero for deep in-the-money European options only at expiration, not before.
What to do instead
Drill a fixed template: intrinsic value = max(0, S - K) for calls and max(0, K - S) for puts; time value = premium - intrinsic value. Apply it to a table of five strikes across three underlying prices, then repeat with a European option to see that early exercise is not available. Never compute intrinsic value from the premium paid by the original buyer.
Applying the wrong sign to a Greek: stating that a long call has positive theta or a short put has positive vega, and then using that sign to predict P&L when volatility or time changes.
Candidates memorize 'long options are long vega' but do not connect the sign of each Greek to the position direction and option type. They also confuse theta (time decay) with rho (interest rate sensitivity) and forget that theta is negative for long options and positive for short options.
What to do instead
Construct a 2x2 matrix: long/short call and long/short put, with the sign and magnitude of delta, gamma, theta, vega, and rho in each cell. For each cell, write one sentence describing the P&L effect of a 1-point rise in volatility and one day of passage of time. Rebuild the matrix from memory before every practice set.
Building a spread or combination and reporting the maximum gain or maximum loss without netting the premiums correctly, or mislabeling a debit spread as a credit spread when the long option is more expensive.
Candidates focus on the payoff diagram and forget that the net premium shifts the break-even and the maximum profit/loss. They also assume that a bull call spread is always a debit and a bear call spread is always a credit without checking which leg is long and which is short.
What to do instead
For every strategy, compute three numbers in order: net premium (debit or credit), break-even, and maximum gain/loss. Check that maximum gain plus maximum loss equals the width of the strikes for a vertical spread, and use that identity to catch sign errors. Label the position as debit or credit only after computing the net premium.
Assuming that a municipal bond's interest is always tax-exempt and comparing its yield directly to a taxable corporate yield without computing the tax-equivalent yield.
Candidates learn 'munis are tax-exempt' as a slogan and miss the exceptions: private activity bonds may trigger AMT, capital gains on muni bonds are taxable, and the exemption applies to federal (and sometimes state) income tax but not to all taxes. They also forget that the comparison requires the investor's marginal tax bracket.
What to do instead
Write the tax-equivalent yield formula (muni yield / (1 - marginal tax rate)) and the after-tax corporate yield formula (corporate yield x (1 - tax rate)) and practice converting both directions. List the three exceptions to muni tax exemption (AMT private activity bonds, capital gains, state tax on out-of-state bonds) and test each bond fact pattern against that list.
Quoting a Treasury bill discount rate as if it were a bond-equivalent yield, or treating the discount rate as the investor's actual return.
Candidates see a T-bill quoted at a discount rate and use it directly in a return calculation, ignoring that the discount is computed on face value and that the bill is purchased at a price below face. They also forget the 360-day versus 365-day convention difference.
What to do instead
Practice converting a bank discount rate to a price and then to a bond-equivalent yield using the standard formulas: price = face x (1 - discount rate x days/360); bond-equivalent yield = (discount rate x face/price) x (365/days). Work three examples with different maturities and verify that the bond-equivalent yield is always higher than the discount rate for the same bill.
Describing a structured product's principal protection or buffer as absolute, without checking the credit risk of the issuer and the participation rate or cap that limits upside.
Candidates read the marketing label ('principal protected note', 'buffer note') and treat it as a guarantee. They miss that principal protection depends on the issuer's creditworthiness, that the note may be callable, and that the participation rate or cap can make the effective return far below the underlying index return.
What to do instead
For every structured product fact pattern, extract four terms: issuer credit, protection level or buffer, participation rate or cap, and call features. Then compute the investor's return under a down scenario and an up scenario using those terms. If any of the four is missing, flag the question as incomplete rather than assuming the most favorable term.
Applying initial margin requirements to a transaction that only requires maintenance margin, or failing to issue a maintenance call when equity falls below the maintenance requirement rather than the initial requirement.
Candidates memorize the 50% initial margin figure and the 25% maintenance figure but do not track which one governs at which point in the trade. They also forget that maintenance requirements can be raised by the firm and that the customer must meet the call within the firm's stated time, not the initial margin deadline.
What to do instead
Draw a timeline: purchase date (initial margin applies), holding period (maintenance margin applies, with firm minimums), and liquidation (maintenance governs). For each stage, write the formula for equity and the threshold. Practice a margin call calculation where the account is between the initial and maintenance thresholds and confirm that no call is issued.
Recommending an options strategy to a customer whose account has been approved only for covered calls or protective puts, without checking that the strategy fits the approved options level and the customer's stated objective.
Candidates focus on whether the strategy is 'suitable' in the abstract and skip the account-level approval step. They also conflate the customer's risk tolerance with the options approval level, which are separate determinations made by the firm.
What to do instead
For each suitability question, write two checks before evaluating the strategy: (1) does the customer's approved options level permit this strategy, and (2) does the strategy match the customer's objective and risk tolerance? If either check fails, the recommendation is unsuitable regardless of the expected return. Practice by sorting ten strategies into approval levels from memory.
Missing the recordkeeping and communication rules that apply to options and structured product recommendations, such as failing to identify which communications require principal review or which records must be retained and for how long.
Candidates treat recordkeeping as a back-office topic and skip it during options study. They also confuse the retention period for different record types and forget that certain retail communications and recommendations require pre-approval or supervisory review.
What to do instead
Build a table with three columns: record type, who must review it, and retention period. Populate it with the options account application, the ODD delivery record, the customer agreement, and retail communications. Review the table weekly and test yourself by covering the retention column and reciting the periods.
