Answer: $5000
Step-by-step explanation:
From the question, it is possible for the customer to borrow 50% of $20,000 which equals:
= 50% × $20,000
= 0.5 × $20,000
= $10,000
We can see that only $8000 was borrowed by the customer, this implies that the customer can still borrow:
= $10,000 - $8,000
= $2000 more.
The above is the SMA for the long account.
For the short account equity, 50% of $30,000 equals:
= 50% × $30,000
= 0.5 × $30,000
= $15,000
The equity in the account is $18,000. This means that there's an extra ($18,000 - $15,000) = $3000
Therefore, SMA will be:
= $3000 + $2000
= $5000
