What is american option?
An American option is a type of options contract that gives the holder the right, but not the obligation, to buy or sell an underlying asset at a fixed price at any time before or on the expiration date.
In simple terms, it allows traders to exercise the option whenever market conditions are favourable, instead of waiting until expiry.
How american options work
American options are based on standard option contracts, which include:
-
Underlying asset such as stocks or indices
-
Strike price where the asset can be bought or sold
-
Expiration date when the contract ends
-
Premium paid to enter the trade
The key feature is flexibility. Traders can:
-
Exercise the option early if the market moves in their favour
-
Hold the option until expiry
-
Sell the option before exercising
This flexibility is known as early exercise, which is only available in American-style options.
Example of an american option
Imagine you buy a call option with:
-
Strike price: $100
-
Expiry: 3 months
If the stock price rises to $120 after 1 month, you can:
-
Exercise early and buy at $100
-
Sell immediately for a profit
-
Or hold the option for further upside
This ability to act early gives traders more control compared to other option types.
