FINRA Series 7Investment Information and Suitable RecommendationsMedium

A client sells short 100 shares of XYZ stock at $40 per share in a margin account. Under Regulation T, what is the minimum initial deposit required?

  1. A$4,000
  2. B$8,000
  3. C$6,000
  4. D$2,000
Show answer & explanation

Correct answer: D. $2,000

The total value of the short sale is 100 shares * $40/share = $4,000. Under Regulation T, the initial margin requirement for short positions is 50% of the sale price. So, 50% of $4,000 is $2,000. FINRA rules also state that the minimum initial equity for a margin account is $2,000, and since 50% of the market value is $2,000, this is the amount required.

Why the other options are wrong

  • A. This is the total value of the short sale, not the required initial deposit.
  • B. This amount is incorrect for this calculation.
  • C. This amount is incorrect for this calculation.

Short Sale Initial Margin (Reg T)

The percentage of the short sale value that a customer must deposit as collateral when selling securities short on margin, as set by the Federal Reserve Board.

  • Currently 50% for most equity securities.
  • Applies to the total market value of the securities sold short.
  • FINRA also has a minimum initial equity requirement of $2,000 for short accounts, which applies if 50% of the short value is less than $2,000.

Memory trick: Shorting means you 'owe' half initially.
