4. Compute the case of margin requirements and restrictions of an account. The initial price of the stock is $50, and we buy 1,000 shares. After that, the price alters. The 3 cases we experience are the price drops to $25, secondly it falls to $45 and thirdly it rises to $60 (note, they are the same as the ones I presented in class.) Assume the initial margin requirement is 60% and the maintenance margin requirement is 25%
