Classifying every character who is paid to give securities advice as a registered investment adviser, without running the three-element definition and the exclusion list. Candidates label a bank trust officer, a lawyer giving incidental portfolio advice, a newsletter publisher, or an insurance agent selling variable annuities as an 'IA' who must register.
The exam deliberately uses realistic job titles that sound advisory but sit inside a statutory exclusion or fail one element of the definition, and candidates pattern-match on the word 'advice' instead of the elements.
What to do instead
On every status question, write three tokens before reading the choices: (1) advice about securities, (2) in the business / holding out, (3) compensation. Then run the exclusions: banks and trust companies, lawyers/accountants/teachers/engineers whose advice is incidental to their profession, publishers of general-circulation publications, broker-dealers and their RRs, and government agencies. If any element fails or an exclusion applies, registration is not required.
Applying a federal exemption that no longer exists, or mixing up the federal versus state registration thresholds - e.g., saying an adviser with $60 million under management must register with the SEC, or that a state-registered adviser at $105 million must immediately switch to federal.
Study material from different eras and the multi-tier numbers ($25M, $100M, $110M, $150M) blur together, and candidates memorize one number instead of the ladder and the buffer rule.
What to do instead
Build a one-line AUM ladder and redraw it from memory: state registers advisers with up to $100M AUM; SEC requires registration at $100M; a $100M-$110M buffer lets a state-registered adviser stay state-registered until it hits $110M; states may not require SEC registration below $25M. Add exempt reporting advisers: private fund advisers under $150M and venture capital advisers - they file reports but do not register. Also remember federal covered advisers still owe states a notice filing and remain subject to state anti-fraud authority.
Choosing 'disclose it in writing' as the answer whenever a conflict of interest appears, even when the rule requires consent or outright prohibition - e.g., an adviser buying a security from a client's account (principal transaction) and merely disclosing it, or charging a performance fee to a client who does not qualify.
Disclosure is the reflexive answer because it is the backbone of fiduciary duty, and candidates stop reading once they see a conflict rather than asking what the specific rule demands.
What to do instead
Before answering, name the transaction type. Principal transaction: written disclosure plus the client's written consent, and the consent should precede completion. Agency cross: written disclosure and client consent, and the adviser cannot act as adviser to both sides of the same trade. Performance fee: permitted only for qualified clients (roughly $1.1M AUM with the adviser or $2.2M+ net worth excluding the primary residence). Pre-arranged trading ahead of a client, borrowing from a client, and buying securities in an IPO for a client's account at the adviser's discretion are prohibited, not curable by disclosure.
Reversing the price-yield relationship or treating duration as if it produced a symmetric estimate - answering that a bond's price rises when market yields rise, or ignoring that a 1% yield move does not change price by the same dollar amount up and down.
Interest rates and prices are described in the same sentence in the study material, and the inverse rule is easy to state but easy to flip under time pressure, especially when the question adds a call feature or a yield-curve twist.
What to do instead
Anchor on one sentence you write down: yields up, prices down. Then use % price change ≈ -duration x change in yield for the estimate, and add that positive convexity means the actual gain from a yield fall exceeds the loss from an equal yield rise. If the question mentions a callable bond, cap the price near the call price (negative convexity) before finalizing.
Treating open-end funds, closed-end funds, ETFs, and unit investment trusts as interchangeable wrappers - saying a closed-end fund issues new shares on demand at NAV, or that an ETF must sell shares to investors at the next computed NAV.
All four hold a portfolio of securities, so candidates classify by what the fund owns instead of by how shares are created, priced, and traded.
What to do instead
Sort by mechanics, not holdings. Open-end: continuous creation/redemption, forward-priced once daily at NAV. Closed-end: fixed share count from an IPO, trades intraday at a premium or discount to NAV, may use leverage. ETF: authorized participants create and redeem in-kind creation units, so intraday price stays near NAV. UIT: fixed unmanaged portfolio with a termination date, redeemable with the sponsor.
Applying one tax regime to every investment vehicle - taxing the inside buildup of a variable annuity annually, treating a listed broad-based index option as short-term capital gain, or assigning ordinary income treatment to a municipal bond's interest.
Vehicle taxation is scattered across the material, and candidates carry over the treatment of the last product they studied instead of matching the vehicle to its rule.
What to do instead
Keep a four-line tax card: variable annuities - tax-deferred inside buildup, nonqualified withdrawals taxed LIFO as ordinary income, death benefits get a step-up; broad-based index options and futures - 60% long-term / 40% short-term under Section 1256; muni interest - federally tax-exempt, capital gains still taxable, and the exemption matters for the in-state/out-of-state distinction; MLPs - largely tax-deferred distributions that reduce basis.
Picking the 'best' investment on the merits - the highest-return fund, the most tax-efficient account placement, the strongest diversification - when the question's facts point to a different answer that actually fits the client's stated objective, time horizon, or constraint.
Candidates are trained to spot the technically superior product and read the client profile as background color rather than as the binding constraint that determines the correct choice.
What to do instead
Restate the client's objective, horizon, liquidity need, and risk tolerance in one line before touching the choices, then eliminate any choice that violates a stated constraint even if it is the textbook favorite. Flag conflict questions: when risk tolerance and risk capacity disagree, the answer must reconcile them rather than default to the higher-risk allocation.
Interchanging broker-dealer suitability/Reg BI with the investment adviser fiduciary standard, or assuming the fiduciary label attaches to every recommendation regardless of who is making it and how they are paid.
Both standards center on the client's interests, so the distinction reads as stylistic rather than substantive, and the exam tests the difference by putting an RR and an IA in parallel fact patterns.
What to do instead
Separate by role and trigger. Broker-dealer: Reg BI applies to a recommendation to a retail customer and imposes four obligations - disclosure, care, conflict of interest, and compliance - and does not create a continuing fiduciary duty to monitor. Investment adviser: fiduciary duties of care and loyalty, a continuing duty to monitor, and full and fair disclosure of conflicts, with the adviser's own form ADV as the disclosure vehicle. If the question asks who owes what, identify the role first.
Misclassifying economic indicators - calling the average duration of unemployment or the CPI a leading indicator, or putting nonfarm payrolls and industrial production in the leading bucket.
All indicators move with the economy, so classification gets done by intuition about whether the statistic 'feels early,' and the CPI trap catches candidates who think inflation leads because the Fed watches it.
What to do instead
Memorize by category anchors. Leading: initial jobless claims, building permits, stock prices, the yield curve, M2, average weekly manufacturing hours, new orders. Coincident: nonfarm payrolls, personal income, industrial production, manufacturing and trade sales. Lagging: average duration of unemployment, CPI, the prime rate, consumer credit-to-income, the inventories-to-sales ratio. When stuck, ask whether the number is set after the fact by the cycle (unemployment duration, bank rates) - that means lagging.
Mixing fiscal and monetary tools and their transmission - saying the Treasury lowers the discount rate, that the Fed raises taxes to fight inflation, or that an open-market purchase raises interest rates.
Both policy arms respond to the same conditions and the same officials appear in the same headlines, so the actor and the tool get decoupled under time pressure.
What to do instead
Tag the actor first: Congress and the Treasury own fiscal policy (spending, taxation, deficit); the Fed owns monetary policy (open market operations, the discount rate, reserve requirements, interest on reserves). Then apply the direction rule: an open-market purchase adds reserves, pushes the fed funds rate down, and is expansionary; a sale drains reserves and pushes rates up. If a choice pairs the wrong actor with the tool, eliminate it before evaluating the economic reasoning.
