| yly14 | calculation for pi is the same for put or call. "d" accounts for the decrease in stock price, not the amount in-the-money of call or put. |
| AusPhD | 3.33 + 60/1.05 - 55 = Put price |
| jd2442424 | Can also use: n = (p_ - p+) / (S+ - S_) PV(TV) = (n * s+ - p+ * 0) / (1 + r)^t p0 = PV(TV) - so * n This would be easier if the 62.3 used n correctly. |
| RAMOST | Put call parity is the fastest way |
