What is the Value Line Composite Index?
The Value Line Composite Index contains approximately 1,700 companies from the NYSE, American Stock Exchange, Nasdaq, Toronto, and over-the-counter markets.1The Value Line Composite Index has two forms: The Value Line Geometric Composite Index (the original equally weighted index) and the Value Line Arithmetic Composite Index (an index which mirrors changes if a portfolio held equal amounts of stock.) These indexes are typically published in the Value Line Investment Survey, created by Arnold Bernhard, the founder and CEO of Value Line Inc.
Understanding Value Line Composite Index
The “value line” from which the index gets its name is a cash flow multiple that Bernhard would overlay on top of a price chart to standardize the various firms’ values. Among the most reputable companies for investing research is Value Line. Its track record of success has been imposing. In fact, over the long term, the company’s model portfolios have outperformed the market.
Except for closed-end funds, all of the Value Line Composite Index firms are also included in the Value Line Investment Survey. Adding or removing firms from the exchanges, mergers, acquisitions, bankruptcies, and Value Line’s coverage selections for the Value Line Index are some variables that affect the number of companies in the Value Line Index. Value Line’s company selection process aims to provide a diverse representation of the North American equities market. Furthermore, a corporation may shift from one exchange to another, be added to or removed from a listing, or have its listings fluctuate on any one exchange. However, whether arithmetic or geometric calculations are used, the delisting or transfer of firms on the markets is not considered in the Value Line Index methodology.
The Geometric Composite Index of Value Line
The initial index was unveiled on June 30, 1961. It is a geometric average-based index with equal weights. By multiplying each stock’s closing price by its prior closing price and then raising the resulting number to the reciprocal of the total number of stocks, one can determine the daily price change of the Value Line Geometric Composite Index.
The Arithmetic Composite Index for Value Line
When this index was created on February 1, 1988, it was based on the arithmetic mean, which approximated the change in the index more accurately than if you had an equal-weight portfolio of stocks. By summing the daily percent change of each stock and dividing by the total number of stocks, one may get the daily price change of the Value Line Arithmetic Composite Index.
Conclusion
- Roughly 1,700 equities from the main market indexes in North America are mixed to form the Value Line Composite index.
- The Value Line Geometric Composite Index and the Value Line Arithmetic Composite Index are the two versions of the index.
- With a daily change closest to the median stock price movement, the Geometric Composite Index is equal-weighted and employs a geometric average.
- Based on an arithmetic mean, the daily changes in the Arithmetic Composite Index represent a portfolio of equities held in identical proportions.
