Global indices 

Global indices 

Global indices are a vital part of the global financial landscape. They offer investors a quick and easy way to gauge the performance of a group of stocks or securities worldwide. These indices comprise stocks from different countries, sectors, and industries and are designed to provide investors with a broad snapshot of the global financial markets. Investors can acquire exposure to diverse equities and lower the risk of investing in individual stocks by investing in global indexes. Understanding global indices is essential for developing an informed investment strategy and a well-diversified investment portfolio, regardless of your experience level. 

What are global indices? 

Global indices are indicators of the performance of stock markets around the world. They are often referred to as world stock market indices or international indices. They are made by following the prices of several equities from various nations and industries and combining them to get a single number representing the market’s performance. Investors, traders, and financial analysts use global indices as crucial indications of the strength and stability of the world economy to evaluate investment opportunities and come to investment judgments. 

Understanding global indices 

Global indices are tools used to measure the performance of a group of stocks or securities worldwide. These indices comprise stocks from different countries, sectors, and industries and are designed to provide investors with a broad snapshot of the global financial markets.  

Global indices can provide several benefits, including diversification and exposure to different regions and industries. Investors can use global indices to track the performance of the world’s stock markets and base their investing decisions on this data. Fund managers use global indices to build index funds and exchange-traded funds that follow the performance of these indexes, in addition to serving as benchmarks for assessing investment performance. 

What is the role of the global indices? 

The role of global indices is to provide a comprehensive snapshot of the overall performance of the world’s stock markets, allowing investors, traders, and financial analysts to gauge the health and stability of the global economy and make informed investment decisions.  

Global indices track the prices of stocks from different countries and sectors, compiling them into a single value representing the market’s overall performance. These indices are important indicators of market trends, investor sentiment, and broader economic conditions.  

Global indices play a critical role in the investment industry as investors use them to evaluate the performance of their portfolios and compare it against market benchmarks. They are also used by fund managers to benchmark their investment strategies against the broader market and to create index funds that replicate the index’s performance. 


How are global indices calculated? 

Global indices are calculated using various methods, but the most common approach is through market capitalisation weighting. This method calculates the value of each company’s outstanding shares multiplied by its stock price, giving greater weight to companies with higher market capitalisations.  

The total market capitalisation of all companies in the index is then divided by a divisor to arrive at the index value. The weights of individual companies within the index are periodically adjusted to reflect changes in their market capitalisations.  

For example, if a company’s market capitalisation increases significantly, its weight in the index may be increased to reflect its increased importance to the overall market. Global indices can also be calculated using other methods, such as price weighting, which assigns a weight to each company based on its stock price, or equal weighting, which gives equal weight to each company in the index regardless of its market capitalisation or stock price. 

Frequently Asked Questions

Investing in global indices provides investors with exposure to a diversified portfolio of stocks worldwide, which can reduce the risk associated with investing in individual stocks. Additionally, investing in global indices can provide opportunities for growth and returns in different regions and industries. 

Numerous global indices track the performance of different stock markets around the world. Some of the most widely followed global indices include S&P 500 (USA), NASDAQ Composite (USA) and Dow Jones Industrial Average (USA). 

No single global index is universally considered the best indicator of the global stock market. Each index has strengths and weaknesses and may be more relevant to certain investors or market participants depending on their investment strategies and objectives.  

Some investors may look to the S&P 500 as a key indicator of the US stock market, while others may prefer the NASDAQ Composite for its focus on technology companies. The best index for investors depends on their investment goals, risk tolerance, and regional preferences. It is important to conduct thorough research and analysis to determine which index or combination of indices is most appropriate for a given investment strategy. 

It is important to note that indices are not investments and therefore do not generate profits or losses independently. Rather, they serve as benchmarks for evaluating the performance of investment portfolios and individual stocks.  

The profitability of an investment in a particular index or set of indices will depend on various factors, such as the investor’s investment horizon, risk tolerance, and market conditions. Some indices may perform better than others over certain periods or market conditions. Still, this performance can also vary widely depending on the specific investments that make up the index.

    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.

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.
