Full question
A customer buys stock in a margin account, but does not pay in the 4 business days required under Regulation T. The brokerage firm can take all of the following actions EXCEPT:
A. sell out the position and freeze the account for 90 days
B. request an extension from FINRA
C. sell short the position
D. use existing SMA (credit line) in the margin account to meet the requirement
sell short the position
If a customer does not meet a Regulation. T. call, the firm is allowed to sell out the unpaid position, the firm can request an extension from FINRA. If there is existing SMA (SMA is the available credit line) in the account, it can be applied towards the call. The firm cannot create a short position (a new position) to cover the long position for which the customer did not pay
