what are points in the stock market

The concept of points in the stock market may seem obscure to some, but it plays a crucial role in determining the value of individual stocks and market indexes. Essentially, a point represents a change in the value of a stock or index, with one point equating to a one-dollar change in value. For example, if a stock trades at $50 per share and increases by one point, its value would rise to $51 per share. Understanding the significance of points can help investors monitor market trends and make informed decisions based on price fluctuations.

While points provide a straightforward way to track value changes, it is essential for investors to consider percentage change as well. Unlike points, percentage change accounts for the proportional increase or decrease in a stock’s value, offering a more comprehensive view of its performance. Additionally, knowing how indexes and their measurements work, as well as how basis points are used, can further enhance an investor’s market understanding.

Key Takeaways

  • Points in the stock market represent a one-dollar change in the value of individual stocks or indexes.
  • Evaluating percentage change alongside points offers a more comprehensive view of stock performance.
  • Familiarity with index measurements and basis points can enhance an investor’s understanding of market trends.

Understanding Points in the Stock Market

What Are Points?

In the context of the stock market, a point refers to the smallest possible price movement of a financial instrument, such as a stock or an index. Points represent the change in the value of a stock or index over a period of time, usually one day. It is essential to understand that points only refer to the dollar amount that has changed and not the percentage of the change.

How Points Relate to Stock Prices

For individual stocks, a point typically represents a one-dollar change in the stock’s price. For example, if a stock’s price increases from $50 to $55, it can be said that the stock has gained five points. However, it is essential to note that two stocks can lose or gain the same number of points while having very different percentage changes.

In some cases, stock market indices use points as well. The Dow Jones Industrial Average, for instance, is a price-weighted stock market index, meaning that the index’s value is determined by the sum of the prices of its component stocks divided by a divisor. As stock prices change, so does the index’s value, measured in points. In this context, a point represents the index’s price movement, not the percentage change.

It is important for investors to understand points in the context of the stock market to accurately assess the performance of their investments. By paying attention to points, investors can have a clearer picture of the dollar value changes in individual stocks and various stock market indices, which can help them make more informed investment decisions.

The Importance of Percentage Change

Percentage Change vs. Points

In the stock market, points refer to the dollar amount that has changed, whereas percentage change represents the proportion of the movement relative to the initial price. Both points and percentage change are crucial for investors to grasp the significance of a stock’s price movement. Two stocks can lose the same number of points but might have different percentage changes due to their varying initial prices. Using percentage change allows for a more accurate comparison between different stocks or market indexes.

Price Change Calculation

To calculate the percentage change of a stock price, follow these steps:

  1. Subtract the original price from the new price.
  2. Divide the resulting value by the original price.
  3. Multiply the result by 100.

This method is common in finance, particularly for tracking the changes in stock prices and market indexes. Understanding the percentage change helps investors determine the magnitude of a stock’s movement and make more informed decisions.

Using points and percentage change, investors can gain a clearer perspective on the stock’s performance and the overall market trend. Though brief, this information is significant for those who want to make calculated decisions in the stock market.

Indexes and Their Measurements

Market Index Overview

A market index measures the price performance of a basket of securities using a standardized metric and methodology. Indexes in financial markets are often used as benchmarks to evaluate an investment’s performance or to track the overall performance of a specific market segment. One well-known index, for example, is the Dow Jones Industrial Average (DJIA), which provides a snapshot of the U.S. stock market by aggregating the values of 30 major blue-chip stocks.

Indexes can help investors understand market trends and gauge the overall health of an economy. By tracking the values of stocks within a specific industry or sector, indexes provide insight into the performance of that specific area or the broader market. This allows investors to assess the risk and potential return of their investments and to make more informed decisions.

Types of Stock Indexes

There are several types of stock indexes that track various investment options, such as equities, bonds, and commodities. The three most popular stock indexes for tracking the U.S. market are:

  • Dow Jones Industrial Average (DJIA): As mentioned earlier, the DJIA tracks 30 major blue-chip stocks, offering a snapshot of the U.S. stock market. The index is price-weighted, which means the stocks with higher share prices have a greater impact on the index’s value.
  • S&P 500 Index: This index comprises the 500 largest publicly traded companies in the U.S. by market capitalization. The S&P 500 is considered a more comprehensive representation of the U.S. stock market compared to the DJIA, as it covers a broader range of companies and industries.
  • Nasdaq Composite Index: This index tracks the stocks listed on the Nasdaq Stock Market, which is known for its technology and innovation focus. The Nasdaq Composite includes more than 3,000 U.S. and international companies, making it a diverse representation of various industries and geographical regions.

When discussing points in the stock market, it is important to note that one point represents a one-dollar change in the stock or index’s value. For example, if a stock trades at $50 per share and increases by one point, its value would be $51 per share. Similarly, points can be used to refer to short-term moves in equity indexes, such as when the “Dow Jones Industrial Average rises by 100 points.”

Basis Points and Their Applications

Understanding Basis Points

Basis points (BPS) are a unit of measure used in finance to describe the percentage change in the value or rate of a financial instrument. One basis point is equal to 1/100th of one percent, or 0.01%. For instance, if an interest rate increases by 25 basis points, that means it has increased by 0.25%.

To convert basis points to a percentage, simply divide the number of basis points by 100. For example:

  • Percentage (%) = Basis Points (BPS) ÷ 100

Interest Rates

Basis points are commonly used to express interest rate changes in various financial markets. By providing a standardized unit of measurement, basis points help investors and professionals to clearly communicate and compare interest rate changes across different financial products.

For instance, when the Federal Reserve adjusts interest rates, these changes are typically communicated in basis points rather than as a percentage. This makes it easier for market participants to compare the impact of policy changes on various instruments such as loans, bonds, and savings accounts.


In the context of bonds, basis points are an essential tool for conveying changes in bond yields. Bond yields are expressed as a percentage and represent the annual interest payment investors receive as a percentage of the bond’s face value. When yields change, market participants often express these changes in terms of basis points to help investors and analysts understand the relative significance of the change.

For example, if a 10-year Treasury bond yield increases from 2.00% to 2.05%, this would be represented as an increase of 5 basis points. By using basis points, investors can make comparisons between different bonds and determine how their investments are affected by shifts in market conditions.

In conclusion, basis points are an essential tool for understanding and communicating percentage changes within the financial industry. They help clarify movements in interest rates, bond yields, and other financial instruments by providing a standardized and universally understood unit of measurement.

Dow Jones Index Components

Dow Jones Industrial Average Components

The Dow Jones Industrial Average (DJIA) is a widely followed stock market index composed of 30 blue-chip companies listed on U.S. stock exchanges. These companies represent a diverse range of industries, from manufacturing to technology, capturing a significant portion of the U.S. stock market’s total value. Some key components include Goldman Sachs Group, Inc., Apple Inc., and Microsoft Corporation.

Dow Divisor

The DJIA’s index calculation is made possible by the Dow divisor, which is a constant value used to adjust the index for various events affecting the component stocks, such as stock splits or dividends. The divisor ensures continuity in the index value when the stock prices of the component companies change. Currently, the Dow divisor is approximately 0.152.

Index Calculation

The DJIA is a price-weighted index, meaning the individual stock prices of the 30 components are used as the basis for the index’s value. To calculate the DJIA value, the sum of the stock prices of all 30 components is divided by the Dow divisor.

As a result, higher-priced stocks have a more significant impact on the index’s value than lower-priced stocks. This method ensures the index accurately reflects the overall market sentiment and allows for easy comparison of changes in the stock prices of the component companies.

For example, if the total sum of the stock prices is $3,000, and the Dow divisor is 0.152, then the DJIA value will be 19,736.84 (3000 divided by 0.152). This calculation expresses the index value in points, which can be used to track short-term market fluctuations or long-term trends.

Price-Weighted Indexes and Other Factors

Price-Weighted Indexes Definition

A price-weighted index is a type of stock market index where each component of the index is weighted according to its current share price. In these indices, companies with higher share prices have a greater weight than those with lower share prices. This means that the movement in prices of the stocks with higher values will have a larger impact on the index’s value compared to stocks with lower values.

Dividend Adjustment

When a company within a price-weighted index pays dividends, it directly affects the index’s value. This is because the company’s stock price decreases by the amount of the dividend payment, causing the index to be adjusted. To accurately calculate the index’s value after a dividend payment, the sum of the stock prices within the index is adjusted by subtracting the dividend amount from the relevant company’s stock price. This ensures that the index value remains consistent and takes into account any changes due to dividend payouts.

Stock Splits

Stock splits are a common practice among companies and have a direct effect on price-weighted indexes. When a company undergoes a stock split, it increases the number of its outstanding shares by issuing more shares to the existing shareholders. This results in a decrease in the stock’s price, impacting the index to which it belongs.

For example, if a company belonging to a price-weighted index has a 2-for-1 stock split, the stock’s price will decrease by half. To maintain the index’s value and ensure that the weight of the stock within the index remains consistent, the divisor of the index needs to be adjusted. This adjustment takes into account the change in the stock’s price due to the stock split, maintaining the correct weighting of all the components within the index.

It is crucial to regularly adjust price-weighted indexes to account for dividend payments and stock splits, ensuring accurate representation of the market and providing investors with the relevant information for making informed decisions.

Changes in Indexes

Mergers and Acquisitions Impact

Mergers and acquisitions can have a significant impact on stock market indexes. When two companies merge or one company acquires another, the combined entity’s stock price, market cap, and revenue may change, affecting the index it belongs to. For example, when General Electric merged with another company, both the individual stock price and the overall value of the index to which it belonged experienced fluctuations. This is because the new combined entity had a different market cap and revenue stream, leading to an adjustment in the index weightings.

Company Changes

Various company changes can also alter the composition of stock market indexes. These changes include stock splits, dividend announcements, and changes in earnings guidance. Companies may undergo stock splits to make their shares more affordable to retail investors, leading to changes in the total number of shares outstanding. Consequently, this change can also impact the market cap and representation of a company within an index. Company changes such as dividend announcements or earnings guidance can cause fluctuations in stock price, which in turn can lead to point changes in the stock market index.


Periodically, stock market indexes are rebalanced to better reflect the current state of the market. During a rebalance, the index provider may remove or add companies based on factors such as market cap, revenue, or other industry-specific benchmarks. These adjustments aim to ensure that the index remains an accurate representation of the market and industry it is monitoring. Rebalances can cause point changes in the index, resulting from the removal of underperforming stocks and the addition of more successful companies.

In conclusion, stock market points are influenced by various factors, including mergers and acquisitions, company changes, and index rebalancing. Understanding these factors helps market participants better gauge the potential impact of these events on indexes and individual stock prices.

Financial Instruments and Market Analytics

Trading Days and Price Movements

A trading day refers to the hours when stock exchanges are open for trading, during which transactions of financial instruments like shares and securities take place. The movements of share prices within these periods play crucial roles in the investment climate. For instance, a single point increase or decrease in the price of a share signifies a one-dollar change.

Understanding price movements is essential for investors to make informed decisions. Some elements that may impact these fluctuations include the overall state of the economybenchmark index movements, geopolitical events, and corporate developments. There is no one-to-one relationship between a decimal point change and the overall value of an investment since each security’s price is determined by market forces.

Financial News Reports and Interpretation

Financial news reports play a significant role in supplying investors with updated and relevant information on financial market activities. They cover various aspects of finance, such as credit card trends, mortgage rates, and market sentiment. These reports also delve into the analytical side by providing insights from analysts about market expectations, growth prospects, and potential risks.

stock market news

Investors need to interpret reports by understanding the context and perspectives of different news sources. Analyzing financial news may reveal valuable opportunities relating to specific financial instruments or the overall market. However, keep in mind that points in mortgages differ from points in stock markets. While each point in a stock market refers to a one-dollar price change, points in mortgages relate to one percent of the total loan amount.

By mastering the art of market analytics, investors can stay more informed and make confident decisions based on a clear and neutral understanding of the various factors impacting their investments.

Frequently Asked Questions

How do you calculate stock market points?

To calculate stock market points, simply subtract the current stock price from its previous price. A positive difference indicates a gain in points, and a negative difference shows a loss in points. One point equals one dollar. For example, if a stock goes from $35 to $37, it gained 2 points.

What is the significance of points in stock trading?

Points in stock trading represent the smallest unit of change for a stock price. They’re used as a measurement to report the financial performance of individual stocks and overall market indices, helping traders and investors assess market movements, make informed decisions, and track their investments.

How does a point affect stock market indexes?

A point affects stock market indexes by contributing to the overall value of the index. Indexes are made up of multiple stocks, and when stock prices change, the seemingly insignificant point movements can significantly impact the overall value of the index. Consequently, the index value may rise or fall depending on the stock performances within it.

What is the relationship between points and percentage?

The relationship between points and percentage is that points represent the actual dollar change in a stock price, whereas percentages represent the relative change in value compared to the initial price. To calculate the percentage change, divide the point difference by the original stock price and multiply by 100. For example, a 2-point increase in a $10 stock represents a 20% gain (2 / 10 * 100 = 20%).

What’s the financial impact of a point drop in the Dow?

The financial impact of a point drop in the Dow Jones Industrial Average (DJIA) can vary due to factors like investor sentiment, market trends, and economic data. However, the Dow is often viewed as a barometer for the overall health of the U.S. economy. A significant drop in points might erode investor confidence, slow down economic growth, and result in declining corporate earnings and stock prices.

How do points differ across various stock exchanges?

Though points generally represent the smallest unit of change in stock prices across different stock exchanges, the actual value and impact of a point can differ due to factors like currency, market capitalization, index composition, and trading volume. As a result, investors and traders should always consider these factors when interpreting point changes on various exchanges.
