Suppose our underlying is a stock XYZ. Today (t=0), XYZ is priced at $1,013. The storage and insurance cost is $19, paid in advance. The forward contract uses XYZ as the underlying, which will expire in one year from today. The interest rate is 0.042. The forward price at today (t=0) is $1,481. What is the arbitrage profit that you can make today based on cost-of-carry model, if you are only allowed to either long or short one forward contract (i.e. do not assume the arbitrage profit is unlimited in this particular case)?
