- Market Value: The customer's market value will decrease because they are selling the shares they bought.
- SMA (Special Memorandum Account): The SMA will decrease because the customer is using their funds to cover the short position.
Overall, buying shares to cover a short position can have a positive impact on credit and may decrease market value and SMA.
