Value Line Composite Index

What Is The Value Line Composite Index?

The Value Line Composite Index covers 1,681 companies. Drawing from multiple sources, including:

• The New York Stock Exchange (NYSE) 
• NASDAQ 
• Toronto Stock Exchange 
• American Stock Exchange 
• Over-The-Counter markets 

Comprising two distinct forms, the Value Line Composite Index catered to varying investment strategies and preferences. 

The first iteration, known as the Value Line Geometric Composite Index, represented the original equally weighted index. It gave investors an unbiased overview of market performance, granting each stock within the index an equal influence on its calculation.

The second form, the Value Line Arithmetic Composite Index, offered an alternative perspective by mimicking the changes that would occur if a portfolio held an equal amount of every stock within the index.

This approach aimed to mirror the investment decisions made by an investor seeking similar exposure to all stocks in the index.

Investors keen on tracking the Value Line Composite Index often turned to the renowned Value Line Investment Survey, where these indexes were published.

The brainchild of Arnold Bernhard, founder and CEO of Value Line Inc., this comprehensive investment resource catered to individuals seeking valuable insights into the stock market.

By providing access to the Value Line Composite Index, investors gained a deeper understanding of market trends and opportunities.

The Value Line Composite Index's diverse composition reflected its aim to encapsulate a broad spectrum of large and small companies from various exchanges and markets. 

The Composite Index continues to shape the investment landscape, thanks to the visionary efforts of Arnold Bernhard and Value Line Inc.

Understanding Value Line Composite Index

The Value Line Composite Index derives its name from the "Value Line," a measure of cash flow that Bernhard utilized to stabilize the valuation of different companies by superimposing it over a price chart.

Value Line Geometric Composite Index

The Value Line Geometric Composite Index, introduced on June 30, 1961, is pioneering and influential in the stock market.

It stands as the original index released by Value Line Inc., and it has gained recognition for its unique calculation methodology and comprehensive market coverage.

Unlike traditional market indices that employ a simple arithmetic average, the Value Line Geometric Composite Index utilizes a geometric average.

This method ensures that each stock's influence on the index's calculation is proportionate to its performance relative to other stocks. The geometric average considers the compounding effect, making it suitable for long-term analysis.

Calculating the Value Line Geometric Composite Index involves multiplying the closing price ratio of each stock by its previous closing price.

The resulting values are then raised to the reciprocal of the stock's total number reciprocal. This approach emphasizes the relative performance of individual stocks and minimizes the impact of high-priced stocks dominating the index.

The main advantage of the geometric composite index is its ability to provide a representative picture of market performance. Its daily price change is closely aligned with the median change in stock price.

This means that extreme fluctuations in a few stocks do not skew the index, as they account for the overall movement of stocks in the market. Investors can rely on the Geometric Composite Index to gauge the overall trend and stability of the market.

The Value Line Geometric Composite Index covers a broad spectrum of companies, including large and small companies listed on various exchanges globally.

This diverse composition allows the index to capture a wide range of market dynamics and provide a comprehensive view of the financial landscape.

Over the years, the Value Line Geometric Composite Index has become a trusted tool for investors seeking an unbiased overview of market performance. It allows investors to monitor trends, identify opportunities, and make investment decisions.

Its use of a geometric average and equal weighting ensures that no single stock dominates the index, providing a balanced representation of the market as a whole.

Calculation of Value Line Geometric Composition

The formula for calculating the Value Line Geometric Composite Index is as follows:

Calculate the daily price change ratio for each stock

Daily Price Change Ratio = (Current Closing Price / Previous Closing Price)

Raise the daily price change ratio to the reciprocal of the stock's total number

Daily Price Change Ratio ^ (1 / Total Number of Stocks)

Multiply the calculated value for each stock together to obtain the geometric average.

Geometric Average = Daily Price Change Ratio1 * Daily Price Change Ratio2 * ... * Daily Price Change Ration

Finally, convert the geometric average into an index level by multiplying it by the base index level:

Index Level = Base Index Level * Geometric Average

By following this formula, the Value Line Geometric Composite Index captures the overall market performance while giving equal weight to each stock's contribution, ensuring a comprehensive representation of the market's movement.

Value Line Geometric Composite Index Example

Consider an example to demonstrate the Value Line Geometric Composite Index calculation.

Suppose we have a simplified scenario with four stocks: Stock A, Stock B, Stock C, and Stock D. Let's assume the following data for the calculation:

Stock A:

• Previous Closing Price: $50
• Current Closing Price: $55
• Total Number of Stocks: 4

Stock B:

• Previous Closing Price: $30
• Current Closing Price: $32
• Total Number of Stocks: 4

Stock C:

• Previous Closing Price: $80
• Current Closing Price: $75
• Total Number of Stocks: 4

Stock D:

• Previous Closing Price: $65
• Current Closing Price: $70
• Total Number of Stocks: 4

1. Calculate the daily price change ratio for each stock:

• Stock A: (55 / 50) = 1.1
• Stock B: (32 / 30) = 1.0667
• Stock C: (75 / 80) = 0.9375
• Stock D: (70 / 65) = 1.0769

2. Raise the daily price change ratio to the reciprocal of the stock's total number:

• Stock A: 1.1 ^ (1/4) ≈ 1.0246
• Stock B: 1.0667 ^ (1/4) ≈ 1.0164
• Stock C: 0.9375 ^ (1/4) ≈ 0.9844
• Stock D: 1.0769 ^ (1/4) ≈ 1.0181

3. Multiply the calculated values for each stock together to obtain the geometric average:

Geometric Average = 1.0246 * 1.0164 * 0.9844 * 1.0181 ≈ 1.0447

4. Assuming the base index level is 1000, calculate the index level:

Index Level = Base Index Level * Geometric Average

Index Level = 1000 * 1.0447 ≈ 1044.7

Therefore, the Value Line Geometric Composite Index would be approximately 1044.7 in this example.

Value Line Arithmetic Composite Index

The Value Line Arithmetic Composite Index was introduced on February 1, 1988, and it employs the arithmetic mean to replicate the index's performance if an investor holds an equally weighted portfolio of stocks.

The daily price change of the index is calculated by summing the daily percentage volatility of each stock and dividing by the sum of the number of accounts used.

Establishing the Value Line Arithmetic Composite Index in 1988 reflects a deliberate approach to capturing the overall market movement through a simplified methodology.

Unlike other indices that utilize complex weighting systems, this index assumes an equal investment distribution across all constituent stocks. This assumption allows the index to act as a benchmark for investors who hold diversified portfolios with equal allocations to each store.

Using the arithmetic mean in calculating the index's daily change implies a straightforward approach to aggregating the price movements of individual stocks.

This approach can provide a clear and easily understandable representation of the overall market performance, directly reflecting the average price fluctuations of the constituent stocks.

One potential benefit of the Value Line Arithmetic Composite Index is its ability to reflect the collective performance of all stocks in a straightforward manner.

By considering each stock equally, it avoids potential biases that could arise from different weighting schemes. However, it is essential to note that this approach may only partially capture the effect of large capital stocks on index performance.

Calculation of The Value Line Arithmetic Composite Index

To calculate the daily change of the Value Line Arithmetic Composite Index, you need to follow these steps:

Step 1: Gather the daily closing prices of all the constituent stocks in the index.

Step 2: Calculate the day-by-day percentage exchange for each inventory by subtracting the previous day's final rate from the cutting-edge day's ultimate price and dividing it by the day before today's ultimate price.

This gives you the daily percentage change for each stock.

Step 3: Sum up the daily percentage changes of all the stocks.

Step 4: Divide the sum of the daily percentage changes by the total number of stocks in the index. This will give you the average daily percentage change for the index.

The resulting value represents the daily change of the Value Line Arithmetic Composite Index, indicating the average movement of the index based on the equal-weighted portfolio assumption.

Value Line Arithmetic Composite Index Example

Let's consider an example of the Value Line Arithmetic Composite Index.

Suppose the Value Line Arithmetic Composite Index consists of stocks: A, B, and C. Here are the closing prices and the number of shares for each stock on Day 1 and Day 2:

Day 1:

• Stock A: Closing price = $50, Number of shares = 100
• Stock B: Closing price = $80, Number of shares = 200
• Stock C: Closing price = $120, Number of shares = 150

Day 2:

• Stock A: Closing price = $55, Number of shares = 100
• Stock B: Closing price = $85, Number of shares = 200
• Stock C: Closing price = $115, Number of shares = 150

To calculate the daily change in the Value Line Arithmetic Composite Index, we follow these steps:

Step 1: Calculate the percent change for each stock:

Stock A: 

((Closing price on Day 2 - Closing price on Day 1) / Closing price on Day 1) * 100

= (($55 - $50) / $50) * 100 = 10%

Stock B: 

((Closing price on Day 2 - Closing price on Day 1) / Closing price on Day 1) * 100

= (($85 - $80) / $80) * 100 = 6.25%

Stock C: 

((Closing price on Day 2 - Closing price on Day 1) / Closing price on Day 1) * 100

= (($115 - $120) / $120) * 100 = -4.17%

Step 2: Sum the percent changes of all stocks:

10% + 6.25% - 4.17% = 12.08%

Step 3: Divide the sum by the total number of stocks:

12.08% / 3 = 4.03%

Therefore, the daily change in the Value Line Arithmetic Composite Index is approximately 4.03%.
