### Comment:
If you buy a call for $3 (x100 shares = $300 per contract) with a 7/20 expiration and the stock goes up in price over the next few weeks the call might be worth $4 so you can just sell it back into the market for a $100 gain. Obviously it's a little bit more complicated than that, but that's the very basic explanation.

### REPLY:
Oooooh ok. Thanks a lot, I was worried I’d need a lot of money laying around to buy the stocks on expiration, and then sell them... if you’ve got the time, how do you make money off puts? Why would someone buy the shares at a higher price than market value? (Last question, thanks for all your help)
