Appendix B: Symbol Construction


Commodity Futures Symbol Construction (from Washington Post help)

Use a year-code digit at the end of each symbol. Example: Cocoa, September, 1996 is "CC=U6". For cash index symbols, always use ZERO as the year-code. Example: S&P 500, Cash is "IN=X0".

Delivery Month Symbol Codes

Jan = F Feb = G Mar = H Apr = J May = K Jun = M
Jul = N Aug = Q Sep = U Oct = V Nov = X Dec = Z

The Washington Post commodity futures help has detailed information on base commodity codes (e.g. Cocoa is CC as above).


Options Symbol Construction

The following tables are used to construct month codes and strike price codes for most listed options. These codes are appended to the ticker symbol (e.g., December ‘96 115 Call contract on IBM is IBMLC).

Jan = A Feb = B Mar = C Apr = D May = E Jun = F
