Activity in Margin Accounts

Now that you understand equity, maintenance, and the Special Memorandum Account (SMA), let's see how common account activities (purchases, sales, and withdrawals) work differently depending on whether the account is restricted or unrestricted.

Additional Purchases in a Long Account

The rules depend on the account's status under Regulation T (Reg T):

• Any purchase increases the debit balance and may reduce SMA
• In a restricted account, the customer can still trade; they just need to deposit the full Reg T requirement for each new purchase

Exam Tip: Gotchas

• Restricted does NOT mean frozen. Customers in restricted accounts can still buy; they just need to deposit 50% of the new purchase price. The account is not locked.

Sales in a Long Account

When securities are sold in a long margin account, the debit balance is reduced by the full sale proceeds, and 50% of the proceeds is credited to SMA (the Reg T loan value released on the shares sold). This 50% treatment is identical whether the account is restricted or unrestricted.

• The SMA credit is 50% of the sale proceeds, never 100%
• Current federal and self-regulatory margin rules do not impose a separate "retention requirement" forcing a restricted account to pay down its debit balance from sale proceeds; that was a legacy NYSE/NASD provision that no longer applies. A restricted account's status still limits new purchases, but a sale is treated the same 50%-to-SMA way as in an unrestricted account

Think of it this way: Selling stock frees up the 50% loan value tied to those shares, and that 50% becomes SMA, no matter whether the account started out restricted or unrestricted.

Example: A customer sells $10,000 of stock:

• The debit balance is reduced by the full $10,000
• $5,000 (50%) is credited to SMA, whether the account is restricted or unrestricted

Exam Tip: Gotchas

• A sale credits 50% of the proceeds to SMA, not 100%. This holds in both restricted and unrestricted accounts. The 100% dollar-for-dollar rule is for cash dividends and cash deposits, not sale proceeds.
• Restricted status does not change the sale-proceeds SMA treatment. Some older prep material describes a "retention requirement" forcing 50% of a restricted account's sale proceeds to pay down the debit balance; that rule is not part of current federal or FINRA margin rules. Restricted status only limits new purchases (50% deposit required).

Cash and Securities Withdrawals

• Cash withdrawal: Reduces equity, increases debit balance; limited by SMA balance; maintenance must still be met
• Securities withdrawal: Reduces both long market value (LMV) and equity; SMA is reduced by 50% of the withdrawn securities' value; maintenance must still be met

Both types of withdrawals are subject to the same constraint: afterward, equity must be at least the greater of $2,000 or the maintenance margin requirement.

Exam Tip: Gotchas

• Withdrawals (cash or securities) are always limited to the greater of $2,000 or the maintenance requirement. Even if SMA shows available funds, a withdrawal that would drop equity below that floor is not permitted.

Simultaneous Purchases and Sales (Same Day)

• If a customer buys and sells on the same day, the transactions may partially offset each other
• The Reg T requirement is calculated on the net increase in market value (if any)
• If the sale proceeds exceed the purchase, excess is released to SMA

Cash Dividends and Interest

• Cash dividends received on long positions are credited to SMA dollar-for-dollar
• Interest charges on the margin loan increase the debit balance (reducing equity)
• Dividends effectively reduce the net cost of carrying a margin position
• Over time, interest charges can significantly erode equity. This is why margin is generally more appropriate for shorter-term positions.

Exam Tip: Gotchas

• Cash dividends increase SMA dollar-for-dollar (they function like cash deposits). Interest charges do the opposite: they increase the debit balance and decrease equity.

What Should You Check on Exam Day?

• New purchases: unrestricted uses buying power, restricted needs a 50% deposit
• Sales always credit 50% of proceeds to SMA, regardless of restricted status
• Withdrawals of cash or securities are capped by the maintenance requirement, not by SMA alone
• Cash dividends and interest move in opposite directions: dividends raise SMA, interest raises the debit balance
