Trading and customer accounts.

Follow the life of an instruction: what the customer wants, how the order behaves, how ownership is registered, and which protections or compliance duties apply.

Translate words into behavior

Every order trades certainty for control.

Market orders prioritize execution.

A market order seeks prompt execution but does not guarantee a price. A limit order controls price but may never execute.

Stop orders change after a trigger.

A stop order becomes a market order when its stop price is reached. A stop price is a trigger, not a guaranteed execution price.

Registration controls ownership.

Individual, joint, custodial, trust, corporate, and retirement registrations create different ownership, authority, and transfer consequences.

Protection has boundaries.

SIPC addresses missing assets at a failed broker-dealer within legal limits. It does not insure a security’s market value or erase unsuitable advice.

Margin is borrowing.

The broker-dealer lends part of the purchase price against eligible collateral. The customer pays interest and can face maintenance demands or liquidation.

Five original questions

Predict what happens next.

1. A customer enters a sell stop order at 42. Once the order is triggered, it becomes:
  1. A limit order
  2. A market order
  3. A day order
  4. A buy order

Answer: B — A market order. Execution is likely after the trigger, but the execution price may be below 42 in a fast market.

2. SIPC protection is primarily designed for a customer who:
  1. Loses money because a stock declines
  2. Is defrauded by an issuer
  3. Has assets missing when a broker-dealer fails
  4. Receives unsuitable investment advice

Answer: C. SIPC helps restore missing cash and securities held by a failed broker-dealer, within statutory limits. It does not insure market value.

3. Under a joint tenants with rights of survivorship registration, a deceased owner’s interest generally:
  1. Passes through probate
  2. Escheats to the state
  3. Passes to the surviving joint tenant or tenants
  4. Is liquidated immediately

Answer: C. Survivorship means the deceased owner’s interest passes to the remaining owner or owners.

4. A sell limit order at 50 may be executed at:
  1. 50 or higher
  2. 50 or lower
  3. Any available price after triggering
  4. Exactly 50 only

Answer: A — 50 or higher. A sell limit establishes the minimum acceptable execution price, but execution is not guaranteed.

5. In a margin account, the customer is primarily:
  1. Lending cash to the broker-dealer
  2. Borrowing part of the purchase price from the broker-dealer
  3. Receiving FDIC insurance on securities
  4. Buying only municipal bonds

Answer: B. Margin lets the customer borrow from the broker-dealer using eligible securities as collateral and paying interest.

Common confusion

Watch the guarantee language.

  • A market order does not guarantee price.
  • A limit order does not guarantee execution.
  • A stop price is not the eventual execution price.
  • SIPC is not protection from market loss.
  • Account registration is not a decorative label; it changes authority and disposition.
