What are indices in trading?
Index trading is a widely favored method for traders to participate in financial markets without the need to directly invest in individual stocks, bonds, commodities, or other assets. Beginners in the financial markets commonly begin with index trading, where they engage in transactions involving an index-tracking fund or a collection of shares, as opposed to dealing with individual company stocks.
In tracking the performance of a diverse group of stocks, a stock index seeks to mirror the overall condition of a broader market, such as a country's stock market or a specific sector. This diversification characteristic makes indices an attractive option for investors.
Every major financial market worldwide is represented by at least one stock index. An example is the S&P 500 (US500), which comprises the 500 largest US companies. These benchmark indices often mirror overall market performance, serving as indicators of the health of the economy or specific industry sectors.
Another notable benchmark index is the Euronext 100 (N100), tracking the performance of leading stocks on Europe's Euronext exchange. It includes companies listed in the Netherlands, France, Belgium, Portugal, and Luxembourg. Other significant indices include the UK's FTSE 100 (UK100), Germany's DAX 40 (DE40), Hong Kong's Hang Seng (HK50), and Japan's Nikkei 225 (J225).
Equity indices act as benchmarks for fund managers to assess actively-managed fund performance. Additionally, passive index-linked funds and associated derivatives are available for investors to trade.
Passive funds, also called tracker funds, replicate the index's stock composition to match its performance. In contrast, active funds are managed by fund managers aiming to surpass the index. Fund managers charge an annual fee as a percentage of the fund's value.
Exchange-traded funds (ETFs) are becoming increasingly popular for stock index trading. ETF fund managers, like Vanguard, charge relatively lower fees, allowing investors to retain more of their returns. Since ETFs are traded on exchanges, their prices fluctuate throughout the trading session, offering quick and easy buying and selling through stock trading platforms.
Dividends from the stocks in an index-tracking fund can either be distributed to investors (distribution fund) or reinvested back into the fund (accumulation fund).
How are indexes of the stock market calculated?
The initial calculation of trading indices involved simple averages, where the share prices of all constituent companies were added and divided by the total number of companies. However, contemporary indices, such as the Nasdaq 100 (US100) and Hang Seng, utilize weighted averages.
Various methods are employed in the calculation of stock indices, considering the types of companies tracked and the index objectives. Some indices assign more weight to stocks with higher prices, others use market capitalization, and some treat all stocks equally. The two primary formulas for calculating the value of a weighted index are price-weighted and market capitalization-weighted.
Price-Weighted:
In price-weighted indices, stocks are weighted based on their share prices rather than the company's size. This implies that companies with higher share prices exert a more significant influence on the index value. Examples of price-weighted indices include the Dow Jones Industrial Average (US30) and Nikkei 225.
Market Capitalization-Weighted:
Market capitalization-weighted indices rank constituent companies based on their overall value. Market cap is determined by multiplying a company’s stock price by its outstanding shares. Companies with larger market capitalization hold more sway over the index’s value. Examples include the FTSE 100 and DAX 40.
Unweighted:
Unweighted or equal-weight indices assign equal importance to each constituent company. This approach mitigates the impact of a single stock on the index, reducing overall volatility and minimizing the effects of sharp movements in individual stocks. The S&P 500 Equal Weight Index (EWI) exemplifies this methodology, offering traders an alternative with enhanced price stability when trading indices.
Types of indices
Various types of stock indices cater to the diverse needs of traders, including global, regional, national, exchange-based, industry-specific, currency-based, and sentiment-based indices. In addition to stock index trading, traders can also engage in commodity and bond index trading.
Stock Indices:
A stock index is derived from the prices of its component stocks, with specific criteria for inclusion. Widely referenced benchmark stock indices serve as indicators of business confidence, performance, and economic health. Trading indices linked to specific industries is popular, such as the NASDAQ 100, which focuses on major non-financial companies listed on the NASDAQ exchange, particularly in the tech sector.
Commodity Indices:
Commodity indices typically follow spot or futures contracts representing commodity prices like crude oil, gold, silver, copper, coffee, and sugar. Examples include the S&P GSCI Crude Oil Index and the United States Oil Fund, which tracks daily price changes for West Texas Intermediate (WTI) crude oil. There are also commodity-linked stock indices representing companies in the commodity sector, like the Energy Select Sector SPDR Fund and the VanEck Junior Gold Miners ETF.
Bond Indices:
Bond indices measure the performance of specific sectors in the bond market, such as corporate, government, and municipal bonds. The S&P 500 Bond Index, focusing on corporate bonds, complements the S&P 500 Index in evaluating market returns.
Currency Indices:
Currency-based indices track the performance of underlying currencies. Examples include the US Dollar Index (DXY), measuring the value of the US dollar against a basket of currencies, and others like the Euro Currency Index (ECY) and British Pound Currency Index (BXY).
Sentiment Indices:
Sentiment-linked indices gauge market sentiment, such as volatility. A notable example is the Chicago Board of Options Exchange (CBOE) Volatility Index (VIX), which measures volatility in S&P 500 index option contracts. Rising VIX indicates increased market volatility, often associated with fear and sell-offs, while lower VIX suggests relatively stable equities.
How to trade indices
If you're keen on learning how to trade indices, there are three primary methods through which traders can incorporate index exposure into their portfolios.
Cash Indices:
Utilized for short-term speculation, cash indices facilitate intraday trading.
These indices typically feature tighter spreads than futures markets and trade close to the spot price.
Traders often close their positions before the end of the day to avoid additional overnight charges.
Index Futures and Options:
Suited for longer-term positions, trading index futures and options comes with wider spreads and overnight fees.
Index futures are derivative products predicting the future value of an index.
Upon expiry, traders can settle the futures contract for cash or extend it into the next period.
ETFs (Exchange-Traded Funds):
A popular avenue for index trading involves buying and selling ETFs and other index-traded funds that mirror a specific index's value.
ETFs invest in index constituent assets with the same weighing, making them suitable for long-term index investing.
Performance charts provided by ETFs offer a straightforward comparison with the benchmark index.
CFDs (Contracts for Difference):
CFDs offer an alternative approach to speculate on index value fluctuations.
They represent a contractual agreement between a trader and a broker, centered on predicting the price difference between the position's opening and closing.
CFDs are leveraged products enabling traders to maximize potential returns with a smaller initial capital.
However, it's crucial to acknowledge the associated risks, as leverage can magnify both gains and losses in CFDs for stock index trading.
