Options quotes follow a pattern that enables you to easily construct and interpret symbols once that formula is understood.

The basic parts of an option symbol are:
Root symbol + Month code + Strike price code

A root symbol is not the same as the ticker symbol. Please refer to the option chain for that ticker to find the corresponding root.

Note: Yahoo also requires the ".X" suffix to identify the security type as an option.

In conjunction with the option root symbol, you can utilize the tables below to assist you in creating or deciphering options symbols.
