You decide to sell short 50 shares of Ford at $10 per share. The initial margin requirement is 50%. The maintenance margin is 40%. What is the minimum amount of cash that must be put into the brokerage account?

$250

Explanation:

Given,

Short sale = 50shares

Current market price = $10 per share

Initial Margin requirement = 50%

Maintenance margin requirement (MMR)= 40%

Total short sales proceeds= 50 x $10=$500

Since the initial margin requirement is 50% which is equal to 50% of $500 or $250. Therefore, $250 worth of stock or cash has to be deposited as the initial margin requirement.

Account value= Short sales proceeds + Initial Margin = $500 + $250= $750

some dynamics markings have a letter 'm,' which remains for mezzo, signifying 'medium.' so a mezzo piano unique stamping resembles this (mp) and intends to play medium calm, while a mezzo specialty dynamic resembles this (mf) and intends to play medium loud.
