Quick Answer
The manipulative and deceptive devices rule is one sentence. No member shall effect any transaction in, or induce the purchase or sale of, any security by means of any manipulative, deceptive or other fraudulent device or contrivance. It names two kinds of conduct, three alternative means, and no exception at all.
This rule sits beside the trading ahead of customer orders rule because this unit groups it with the conduct aimed at a customer whose order the member is handling. The rule's own sentence reaches any transaction in, or the inducement of the purchase or sale of, any security, and that breadth is what a fact pattern usually tests.
What Conduct Does the Rule Reach?
The rule reaches two kinds of conduct, and either one is enough.
- Effecting any transaction in any security.
- Inducing the purchase or sale of any security.
The duty-bearer the text names is the member. The instrument is any security, with no product limit written into the sentence.
The means is stated in three alternatives joined by "or": a manipulative device or contrivance, a deceptive device or contrivance, or another fraudulent device or contrivance. Conduct needs to answer only one of the three.
Exam Tip: Gotchas
- Inducing is conduct on its own. A member that never executes anything can still be inside the rule by inducing a purchase or sale, so an answer that requires a completed proprietary trade reads the sentence too narrowly.
- The three means are alternatives, not a cumulative test. A device that is deceptive without being manipulative is inside the rule, and so is one that is fraudulent without being either.
- The instrument is any security. The sentence carries no equity limit and no dollar threshold, so scoping the rule to the products a trading desk quotes understates it.
How Does It Differ From the Trading Ahead Rule?
The two rules are easy to confuse in a customer-order scenario, because one set of facts can raise both. They are built differently.
| Feature | Manipulative and deceptive devices rule | Trading ahead of customer orders rule |
|---|---|---|
| Instrument | Any security | An order in an equity security |
| Conduct | Effecting a transaction, or inducing a purchase or sale | Holding a customer order without immediately executing it and trading same-side proprietarily at a satisfying price |
| Exceptions in the text | None stated | Eight items of Supplementary Material, five of them exceptions |
| Thresholds in the text | None stated | Several, including a share-count and order-value test inside one exception, six minimum price improvement bands plus a seventh branch for an order priced outside the best inside market, a 60-second allocation window, and normal market hours of 9:30 a.m. to 4:00 p.m. Eastern Time |
Exam Tip: Gotchas
- A carve-out from the trading ahead rule relieves only that rule's obligations. The manipulative and deceptive devices rule states no exception, so qualifying for the institutional or riskless principal route says nothing about it.
- The two rules can reach the same trade. They test different things, so a fact pattern that satisfies one exception can still describe deceptive conduct.
Where Is Market-Facing Manipulation Covered?
This unit takes the conduct aimed at a customer whose order the member handles. Manipulation aimed at the market itself, including front running of block transactions, trading ahead of research reports, and spoofing, is covered in the unit on identifying and avoiding prohibited activities.
Exam Tip: Gotchas
- The rule's own text draws no line between customer-facing and market-facing conduct. The split is how this course organizes the material, so do not read the rule as limited to a customer's order.
What Should You Check on Exam Day?
- Ask whether the member effected a transaction or induced a purchase or sale; either one is enough to reach the rule.
- Do not look for an exception or a threshold in this rule, because the sentence states neither.
- Confirm the instrument is a security, and resist narrowing the rule to equities.
- Where a trading ahead exception applies, check the conduct separately for a manipulative, deceptive or other fraudulent device.
- Match only one of the three named means; the rule joins them with "or."
