What You'll Learn

In this unit, you'll cover:

  • Margin accounts and margin requirements: How borrowing is secured, and how initial and maintenance requirements differ.
  • Accounts permitted to trade on margin: Why an approved margin account and a customer agreement are required before credit is extended.
  • Margin documentation, disclosures, and calls: What customers receive, what a deficiency means, and when a firm can liquidate.
  • Stock lending and short sales: How borrowed securities support delivery and how short sales are marked and located.
  • Day trading and buying power: The pattern day trader standard, minimum equity, buying power, and call restrictions.

Why This Matters

Margin adds credit risk to a securities transaction. A customer can lose value, fall below a required equity level, and face a call or liquidation.

Operations professionals need to recognize the account authorization, collateral, delivery, and buying-power controls that keep those risks within required limits.


Let's start with margin account mechanics and the difference between the amount needed to buy and the equity that must remain.
