Option Premium Timing and European, American, and Bermudan Exercise

Summary

This introductory explanation clarifies the meaning and timing of an option premium and distinguishes exercise rules by option style. In the example, the quoted trading price of a call is its premium: the buyer pays that amount when entering the option contract, rather than waiting until maturity. The premium is the cost of acquiring the option, separate from the decision to exercise it.

The note explains that a European option may be exercised only at maturity, while an American option can be exercised at any time before or at maturity. A Bermudan option permits exercise only on a specified set of dates. These definitions answer the basic terminology questions, but the example does not discuss contract multipliers, settlement conventions, bid–ask spreads, or how premium and exercise decisions depend on market conditions. The explanation is introductory and does not cover option valuation.

Key ideas

• The option’s trading price is its premium, paid by the buyer when purchasing the contract.
• European options can be exercised only at maturity.
• American options allow exercise before maturity, subject to the contract terms.
• Bermudan options allow exercise on a discrete schedule of dates.

I'm not clear for the terminology of options and the mechanics of it. Any help is appreciated. For example the following statement:

> European call option of Apple stock with maturity 1 year and strike price $15. The option is trading at 13 dollars.

- Is it correct to say that the premium is $13 for this call option?

- When is the premium paid, when the buyer buys the option or at maturity?

- Can the holder of the option exercise it whenever he wants or should wait for the maturity?

Thanks in advance

- Yes the option premium is $13. Premium just means how much you have to pay for the option

- The premium is paid upfront, so whenever the buyer enters the contract/buys the option

- European options can only be exercised at maturity. An American option is the type of option that can be exercised before maturity at any time. A Bermudan option can be exercised at a discrete set of dates before maturity.
