Why is the last statement correct? Short call option is in the money when underlying price is below strike, therefore short position in call option has value |

remember the formula CT=ST-X? if ST ,which is the Stock Price, is less than or equal to X, which is the Exercise Price, the CT (Call Option Value) will either be negative or zero. And since options could not be valued as negative, we carry them as zero. |
