put premium = (((Strike priceX e^-(rt)) + call premium) - Spot price | ||||||
e^-(rt) = e-^(0.03X1) = e ^-0.03 = 0.970445501203472 | ||||||
(Strike priceX e^-(rt)) =1390 X 0.970445501203472 | 1348.919247 | |||||
put premium = 1348.91924667283 + 21.35 - 1380 = 12.8411890903007 | ||||||
Put premium rounded = $12.84 | ||||||

and buy Call at $21.35, then net balance = 1399.25-21.35 =1377.90 | ||||||
and invest this for 1 year, then we will get = 1377.9 X e^rt = 1377.9X 1.03045456829866 = | 1419.8633496587 | |||||
When gold jewellary price goes above $1390, we will exercise call option, then we will get back our share At $1390 | ||||||
our gain will be $1419.86334965872 - 1390 = $29.8633496587199 | ||||||
