Two little words trip up almost every beginner: call and put. They sound abstract, so let us anchor them to things you already do, and then you will never mix them up again.
Here is the whole chapter as a mnemonic: a call is a coupon, a put is a return receipt. Keep those two pictures and the rest is easy.
A call is a coupon
Picture a coupon that says "buy this jacket for $80, anytime this month." If the jacket goes on to sell for $120, you are thrilled: you still pay $80 and you are $40 ahead. If it drops to $50, you just ignore the coupon and buy it at the lower price like everyone else. A coupon only helps when the price goes up. That is a call: the right to buy at a locked price, useful when the price rises.
A put is a return receipt
Now picture a receipt that says "you can sell this jacket back for $80, anytime this month." If the jacket crashes to $30, you are protected: you return it for $80 and dodge the loss. If it climbs to $120, you shrug and keep it. A return policy only helps when the price goes down. That is a put: the right to sell at a locked price, useful when the price falls.
The two words, side by side
- Call = right to buy at the strike. You want the stock to go up.
- Put = right to sell at the strike. You want the stock to go down, or you want a floor to sell at.
If you only remember one thing today: a call is a coupon, a put is a return receipt. Every strategy in this library is just built on top of those two little rights.
Which side are you on?
Every option has a buyer and a seller. You can hold a coupon, or you can be the shop that hands one out and collects a fee for it. You can hold a return receipt, or you can be the one who sells that protection. Income traders usually sell: they hand out the coupon or the return policy and pocket the premium up front. We will get deep into that, but for now, just lock in the two words.
- A call is a coupon: the right to buy at a set price, good when the price rises.
- A put is a return receipt: the right to sell at a set price, good when the price falls.
- Call buyers want the price up, put buyers want it down. Sellers of either one collect the premium.
