Value Line Composite Index

The Value Line Composite Index was launched on the Kansas City Board of Trade (KCBT) in 1982, pioneering the first market index to trade futures market, ushering in a ground-breaking approach to risk management. KCBOT dropped the Value Line indices (Arithmetic and Geometric) effective 30th Aug 2013 and shifted the exchange distribution to NYSE’s Global Index Feed.

• Value Line (Geometric) Average – The Value Line Geometric Composite Index is the original index released, and launched on June 30, 1961. It is an equally weighted index using a geometric average. Because it is based on a geometric average the daily change is closest to the median stock price change.
• Value Line (Arithmetic) Average – The Value Line Arithmetic Composite Index was established on February 1, 1988, using the arithmetic mean to more closely mimic the change in the index if you held a portfolio of stocks in equal amounts.
