Basics

Call and Put explained simply

Call = right to buy. Put = right to sell.

Core idea

What matters

A call benefits from rising prices, a put from falling prices.

The buyer has a right, the seller takes on an obligation.

Example

Stock at 100 EUR

Call strike 95 Becomes more attractive if the stock rises.
Put strike 105 Becomes more attractive if the stock falls.
Shortcut Call = upside, Put = downside or hedge.
