Market Indexes

Market Indexes

Stock market indexes represent a group of shares that have been selected based on certain criteria, such as trading volume, share size, etc. In the stock market, the sampling method is used to illustrate the direction of the market and movement through an index. 

What are market indexes? 

A stock market index is a statistical measure of the relative changes in the value of a portfolio of stocks. The Dow Jones Industrial Average (DJIA) and the Standard & Poor’s 500 Index (S&P 500) are the most commonly used stock market indices. 

The DJIA is a price-weighted average of 30 blue-chip stocks widely considered a barometer of the overall US stock market. The S&P 500 is a market-cap-weighted index of 500 large-cap stocks widely considered representative of the US stock market. 

Understanding market indexes 

A stock market index keeps tabs on the performance and price changes of the stocks that make up the index. This indicates that the performance of the stocks that make up any stock market index is directly correlated with the index’s performance. In layman’s terms, the index generally increases if the prices of the stocks in it rises. 

Equities with comparable market capitalisations, company sizes, or industry sectors are combined to create stock market indices. After that, the index is calculated using the chosen stocks. Nevertheless, the price of each stock will be unique, and the price point in one stock will differ from the price point in another. Therefore, it is impossible to calculate the index value by adding stock prices. 

Types of market indexes 

There are three main types of stock market indexes in the United States: the Dow Jones Industrial Average (DJIA), the Nasdaq Composite, and the S&P 500.  

  • Dow Jones Industrial Average (DJIA) 

The DJIA is the oldest and most well-known index and consists of 30 large blue-chip stocks traded on the New York Stock Exchange (NYSE).   

  • Nasdaq composite 

The Nasdaq Composite is a newer index that includes all stocks traded on the Nasdaq stock exchange, including both large and small companies.  

  • S&P 500 

The S&P 500 is a broad-based index that includes 500 large-cap stocks traded on the NYSE and Nasdaq. 

Advantages of market indexes 

Stock market indexes are a useful tool for investors to track the stock market’s overall performance. By tracking the performance of a broad range of stocks, indexes can give investors a good indication of how the stock market is performing.  

This can help make investment decisions, as it can indicate whether the stock market is bullish or bearish. 

In addition to giving investors an overview of the market, indexes can also be used to measure the performance of specific market sectors. For example, the S&P 500 is divided into 11 different sectors including energy, materials, industrials, consumer discretionary, and healthcare. This can help identify which sectors are performing well and which are struggling. 

Overall, stock market indexes are a useful tool for investors to track the stock market’s performance and make informed investment decisions. 

Disadvantages of market indexes 

While stock market indexes can provide a quick snapshot of how a particular market is performing, they also have some disadvantages. For example, because indexes are created using a weighted average of the stocks within the index, they may not accurately reflect the performance of any one particular stock. Additionally, because indexes only track a limited number of stocks, they may not provide a true representation of the entire market. 

Frequently Asked Questions

A stock index list is a list of stocks grouped based on certain criteria. A panel of experts usually chooses the stocks in an index list designed to represent the stock market’s overall performance or a specific economic sector. Investors often use index lists to track the performance of the market or a specific sector. 

A weighted index is a stock market index in which each component stock is assigned a weight, or a value, based on its market capitalization. The weight of a stock is determined by its market capitalization, which is the total value of all the outstanding shares of that stock. The weighting of the stocks in the index makes it a “weighted” index.  

Investors use stock market indices for a variety of purposes, such as: 

  • To measure the performance of a particular stock market or market sector. 
  • To compare the relative performance of different stock markets or market sectors. 
  • To provide a benchmark for active portfolio managers. 
  • To help investors formulate investment strategies. 
  • To track the performance of exchange-traded funds and index mutual funds. 

To read a stock market index, one must first understand its measures. A stock market index is a statistical average that measures the performance of a group of stocks. This can be done by taking the weighted average of the prices of the stocks in the group.  

The index can be either a value or a growth index. A value index measures the stocks in the group based on their current prices. A growth index measures the stocks in the group based on their prices and dividend growth.

You must also know how the index is calculated. Once you understand what the index is measuring and how it is calculated, you can start interpreting it. The index can be used to measure the stock market’s overall performance. It can also be used to compare the performance of different groups of stocks. For example, you can compare the performance of large-cap stocks to small-cap stocks. 

Understanding what the stock market index measures is the first step to reading it. Once you understand what it measures, you can interpret it and use it to make decisions about investing in the stock market. 

A stock index, sometimes known as a stock market index, is an indicator used in finance to evaluate a stock market or a segment of a stock market and assist investors in comparing current stock prices to historical prices to determine market performance. 

Equities from comparable companies or those that meet a predefined set of criteria are chosen to create a stock market index. These securities are already traded and listed on the exchange. Market capitalization, industry, and other factors may all be used to create share market indices.

A copy of the Prospectus and PHS are available from PCM, any of its Participating Dealers (“PDs“) for the ETF, or any of its authorised distributors for the unit trust managed by PCM.  

    An ETF is not like a typical unit trust as the units of the ETF (the “Units“) are to be listed and traded like any share on the Singapore Exchange Securities Trading Limited (“SGX-ST”). Listing on the SGX-ST does not guarantee a liquid market for the Units which may be traded at prices above or below its NAV or may be suspended or delisted. Investors may buy or sell the Units on SGX-ST when it is listed. Investors cannot create or redeem Units directly with PCM and have no rights to request PCM to redeem or purchase their Units. Creation and redemption of Units are through PDs if investors are clients of the PDs, who have no obligation to agree to create or redeem Units on behalf of any investor and may impose terms and conditions in connection with such creation or redemption orders. Please refer to the Prospectus of the ETF for more details.  

    Investments are subject to investment risks including the possible loss of the principal amount invested. The purchase of a unit in a fund is not the same as placing your money on deposit with a bank or deposit-taking company. There is no guarantee as to the amount of capital invested or return received. The value of the units and the income accruing to the units may fall or rise. Past performance is not necessarily indicative of the future or likely performance of the Products. There can be no assurance that investment objectives will be achieved.  

    Where applicable, fund(s) may invest in financial derivatives and/or participate in securities lending and repurchase transactions for the purpose of hedging and/or efficient portfolio management, subject to the relevant regulatory requirements.

    The regular dividend distributions, out of either income and/or capital, are not guaranteed and subject to PCM’s discretion. Past payout yields and payments do not represent future payout yields and payments.
