📊 Margin Accounting (Long, Short, Day Traders) – Series 7 Exam Guide
Mastering the Rules of Margin for Success on Exam Day
Margin accounts are a core concept tested heavily on the Series 7 Exam. Whether customers are buying long, selling short, or actively day trading, you need a clear understanding of how margin works, how it’s calculated, and what the regulatory requirements are.
📈 Margin for Long Positions (Buying on Margin)
Buying on margin means the customer borrows part of the purchase price from the broker-dealer.
Key facts you must know:
- Minimum Initial Requirement:
- If the purchase is $2,000 or less, the customer must deposit 100%.
- If the purchase is over $2,000, the customer must deposit the greater of $2,000 or 50% of the purchase price.
- Maintenance Requirement:
- After the trade, the customer must maintain at least 25% of the market value in equity at all times.
- If equity falls below 25%, a margin call occurs.
📉 Margin for Short Positions (Short Selling)
Selling short involves selling borrowed securities and hoping to buy them back cheaper later.
- Minimum Initial Requirement:
- Minimum deposit is $2,000, regardless of transaction size.
- The customer must deposit the greater of $2,000 or 50% of the short sale proceeds.
- Maintenance Requirement:
- Must maintain at least 30% of the current market value (or higher for low-priced stocks).
⚡ Margin for Pattern Day Traders
Pattern Day Trader (PDT):
A customer who executes 4 or more day trades within 5 business days, if the number of day trades is more than 6% of total trades.
Special rules for PDTs:
- Minimum Equity Requirement:
Must maintain at least $25,000 equity in the account at all times. - Buying Power:
Day traders can trade up to 4 times their maintenance margin excess. - Margin Calls:
If equity falls below $25,000, the account is restricted until the customer deposits funds.
🔢 Key Terms to Understand
- Regulation T:
Federal Reserve Board rule requiring 50% initial deposit for margin trades. - House Maintenance:
Broker-dealers may require higher standards than the regulatory minimum. - Margin Call:
A demand for additional funds when equity falls below maintenance levels. - SMA (Special Memorandum Account):
Represents excess equity that can be borrowed for new purchases.
🧠 Common Series 7 Exam Traps
- Know when $2,000 minimum rules override the 50% Regulation T rule.
- Remember the 30% maintenance for short positions (not 25%).
- Watch for questions about day trading minimum equity ($25,000 rule).
- Expect questions calculating how much equity is needed after price changes.
