Carefully draw the payoff diagram of a portfolio consisting of a long position in two call options with exercise price K, a short position in five call options with exercise price 2K and a long position in four call options with exercise price 3K. All options have the same maturity date and the same underlying stock. What reasons could a speculator have for holding such a portfolio (explain in detail)? c) Draw the profit diagram of the portfolio above (and clearly state any assumptions you make). Recall that the profit is equal to the difference between the payoff of the portfolio at expiry (maturity) date and the cost of the portfolio. Is the cost of the portfolio positive?
