The following diagram depicts the valuation of a European call option which has a strike price of $55 using a 1-step binomial tree. The proportional up ("u") and down ("d") movements on this tree are 1.4241 and 0.7022 respectively. The branch length ("St) is 0.50. The riskfree interest rate is 4% per annum continuously compounded. Sy = $85.45 Cu = $30.45 So = $60 Co = ? Sa = $42.13 Ca= $ 0 Time 0 Time 1/2 St = 1/2 You will calculate the value of the call option today ($Co) using the delta-hedging approach. Answer each of the following questions, giving your answer to 2 decimal places. On this branch, delta (4) is equal to which means that you need to the underlying shares. At time 0, in addition to entering a position of A shares, you also need to enter a position in the call option itself. If you set up a delta hedge at time 0, the dollar value of your two-piece delta-hedged portfolio at the end of the branch is At time 0, the value of the call option (Co) is Do not enter any dollar signs ($).
