What is a short margin Account
The proceeds of short sale transaction are usually deposited in the short margin account. The short sale transaction is a transaction that involves the borrowing of shares by an investor to sell on the market with the hope that he/she will be able to then buy them back when the share price decreases in the future.
Therefore, if the market value of the ABC shares falls to $9,000, the equity
= Short Margin Account Credits - The value of the Short Market Value
= $16,000 - $9,000
= $7,000
