An investor buys a stock for $40 per share and simultaneously sells a call option on the stock with an exercise price of $43 for a premium of $3 per share. Ignoring dividends and transaction costs, which of the following is the maximum profit the writer of this covered call can earn if the position is held to expiration? 请问为什么是6？未行权，所以理论上理解为挣了3元；假定P会上升到43，则行权，因不考虑成本，所以gain=3，一共为6，这样理解是否正确？谢谢。
