A non-dividend paying stock has a price of $100. A 3 month Eurpoean call option on the stock with a strike of $95 is worth $9.90. Similarly, a 3 month European put option with the same strike is worth $3.80. If the continuously compounding interest rate is 5% per annum, is there an arbitrage opportunity? If so, how could you set up a portfolio to make a profit from it now (not having to wait for 3 months), and how much is that profit?
