Buying power
SMA balance divided by 50% Reg T requirement (i.e. SMA x 2). Means customer can purchase x amount of stock on margin without depositing additional cash.
Minimum maintenance requirement (long accounts)
Who is it established by?
What is the % requirement?
Established by FINRA not FRB.
25% minimum for a long account, i.e. equity must be at least 25% of current market value. If equity drops below, BD must call for additional margin (maintenance call/margin call) to bring equity to 25%.
Shortcut to determine trigger point: Debit balance * 4/3 = Market value at which margin call would kick in
Guarantees involving customers
Account of a customer may be guaranteed by another customer (must be in writing) , i.e. if a customer’s account becomes undermargined, other customer account equity can be used as collateral
Minimum initial equity requirement ($)
$2,000 unless purchase is less than $2,000 (then the requirement is the full purchase price)
Ex. $3,000 initial purchase = $2,000 initial deposit
$1,800 initial purchase = $1,800 initial deposit
Initial deposit requirement only, not maintenance requirement
Credit balance
Represents short sale proceeds plus required cash margin deposit
Initial margin requirement is the same 50%
Ex. Customer who sells short $10k worth of stock will be credited $10k proceeds + required to deposit $5k initial margin = $15k credit balance
Short market value
Current market price of borrowed stock (amount customer owes back to broker)
Calculating equity on short accounts
Credit balance - short market value = equity
Similar to long accounts, formula is always “assets - amount owed = equity”
Minimum maintenance requirement (short accounts)
Generally, 30% of market value of short stock
Shortcut to determine trigger point (assuming 30% requirement): credit balance * 10/13 = Market value at which maintenance would kick in
Exceptions:
1. If stock being sold short is valued <$5/share, requirement is $2.50 per share or 100% of the current market value, whichever is greater
2. If stock being sold short is valued between $5 and $16.66/share, requirement is $5.00 per share
3. If stock being sold short is valued >$16.66/share, requirement is 30% of current market value
Margin requirements for US Gov’t and Municipal securities
FRB hasn’t established any minimums, leaving it up to SROs
FINRA has set the following:
Governments: Depends on time remaining to maturity, ranging from 1% (<1 year) to 6% (20+ years)
Muni bonds: 7% initial and maintenance requirement
Pattern day trader
Customer who day trades 4+ times in a 5-business day period, and number of day trades is >6% of total trades in that period
Gets special rules for margin
If a BD knows or has reason to believe a customer opening an account will engage in pattern day trading, BD can impose special rules immediately
Day trading
Purchase and sale (or vice versa) of the same security on the same day in a margin account, except for long/short positions held overnight and sold/purchased the next day prior to any new purchase/sale of the same security
Special rules for pattern day traders
Margin on option contracts
Option contracts, while they typically have no loan value, are subject to Reg T margin requirements and exchange maintenance requirements. Since they have no loan value, buyer of an option must deposit the full purchase price, regardless of whether the option is bought in a cash or margin account.
Must be paid for within T+4, then BDs must clear transactions and deposit margin with the OCC the next business day
A BD can require deposit from customers prior to Reg T payment date
OCC
Options Clearing Corporation
Covered call option
underlying stock/security (or escrow receipt) is on deposit with the firm
Escrow receipt
Letter from the bank saying that a stock is on deposit at the bank and will be delivered if the call is exercised
Covered put option
Aggregate exercise price (or bank guarantee letter) is on deposit with the firm
Bank guarantee letter
Letter from the bank saying that the bank holds cash equal to the aggregate exercise price and will pay against delivery on the underlying stock if the put is exercised
Writer
Grantor of an option
Margin requirement for covered call writer
None because covered = writer is long the stock or escrow receipt
Margin requirement for uncovered call writer
If call is ITM or ATM, 20% market price of the underlying stock + premium (amount ITM is irrelevant)
If call is OOTM, greater of:
1. 20% market price of the underlying stock + premium - amount OOTM
2. 10% market price of the underlying stock + premium
Remember these are to calculate total margin requirement. However, typically the premium is not typically taken into account for the “deposit amount” owed by the writer, since that is paid and deposited by the buyer.
Also pay attention to the NUMBER of calls sold x100 for each
In the money (ITM)
Exercise price lower than market price
Option premium
“purchase price” of option (remember to assume x100 for 100 share unit)
Margin requirement for covered put writer
If writer is short the underlying stock, has cash equal to the exercise price, or has a bank guarantee letter - no margin required
