A put becomes more valuable as the price of the underlying stock depreciates relative to the strike price. For example, if you have one Mar 08 Taser 10 put, you have the right to sell 100 shares of Taser at $10 until March 2008 (usually the third Friday o

of the month). If shares of Taser fall to $5 and you exercise the option, you can purchase 100 shares of Taser for $5 in the market and sell the shares to the option's writer for $10 each, which means you make $500 (100 x ($10-$5)) on the put option. Note

call option 은 그 반대입니다. 주식 값이 올라가야 벌수있죠.

어렴풋이 알고 있었지만 이렇게 정리해주시니 명확해 집니다. 감사합니다.
