CBOE Gold Index

CBOE Gold Index stands for the Chicago Board Options Exchange (CBOE) Gold Index. The symbol for the CBOE Gold Index is GOX. The CBOE Gold Index tracks the prices of companies (i.e. there were 12 in 2008) involved in the production and mining of gold. The CBOE Gold Index is a price weighted index, modified using an equal weight approach to ensure that all companies included in the CBOE Gold Index carry the same value. At its inception in 1994, the CBOE Gold Index was set at 100 points. The CBOE Gold Index is published during trading hours and updated every 15 seconds. CBOE is responsible for maintaining and calculating the CBOE Gold Index. The CBOE Gold Index is reviewed quarterly when the CBOE conducts its quarterly share update and re-adjusts all shares to maintain an equal value for all companies included in CBOE Gold Index. This update occurs after the close of trading which is on the third Friday of March, June, September and December. CBOE can also, at its discretion, add or remove a company from the CBOE Gold Index in order to respond to changes in the gold industry and to ensure that the companies included in the CBOE Gold Index are still a fair representation of gold production and mining companies.
