Construct a table showing the investor?s profit (not payoff) as a function of the stock price at expiration.Hints: To answer Q1, construct a column in Excel of stock prices ranging from $1 to $100 in increments of $1. Then use the next 3 columns to calculate the stock, put, call profits (one column for each position). Pay attention to whether the investor is taking a long or a short position of the option. Then add all the profits from these three positions (stock, put, call). Finally, use Excel to graph the portfolio profit (y ?axis) as a function of stock price (x? axis).
