From 1970 to 1989, the show used the Wall Street Week Index (later known as the WSW Technical Market Index), a composed financial index developed by Robert Nurock. The analysis consisted of ten separate technical indicators, each of which was assigned a value of either +1 (indicating a bullish trend), -1 (for a bearish trend, or 0 (neutral)). A net balance of +5 (or higher) was interpreted as a buy signal, while a reading of -5 (or lower) was a sell signal. Rukeyser irreverently named the index "The Elves" (a reference to the term Gnomes of Zurich), and dubbed Nurock the "Chief Elf." After being in neutral for a considerable period of time, Rukeyser requested significant changes in the makeup of the index. Nurock refused since he believed his ten indicators were still the best way to judge the technical aspects of the market. This ended Nurock's association with the show and the Index was replaced.
