An arbitrageur observes a six-month European call struck at 50 trading for 4.50 and a six-month European put struck at 50 trading for 2.50. The stock price is 51 and the risk-free rate is 4%.

According to Put-Call Parity (C - P = S_0 - Ke^-rT), is there an arbitrage opportunity?

  1. No, because C - P should equal S_0 - K, and 2.00 = 51 - 50 is close enough.
  2. Yes, because the call price should always be at least 5 higher than the put price when the stock is at 51.
  3. No, because the difference of 0.01 is too small to be an arbitrage.
  4. Yes, because the synthetic stock price C - P + Ke^-rT ≈ 51.01 is higher than the actual stock price.
