For anyone trying to understand the stock market, one of the most essential concepts is that of a stock market index. It serves as a barometer for the overall market or specific segments within it, offering a snapshot of market trends, investor sentiment, and economic health. If you're searching for "stock market explained for beginners," stock indices are a great place to start.

What is a Stock Market Index?

If you're looking to understand the stock market better, a good place to start is with the question: What are stock indices? A stock index is a statistical indicator that tracks the performance of a selected group of stocks, typically representing a particular sector, industry, or the market as a whole. These indices offer a snapshot of market movements and investor sentiment.

Instead of monitoring hundreds of individual stocks, investors and analysts use stock indices to quickly gauge how a section of the market is performing. For example, if most of the stocks within an index rise in value, the index goes up—signaling a positive trend. Conversely, if the majority of constituent stocks decline, the index falls.

Stock indices are essential tools for understanding market trends, comparing returns, and benchmarking performance. They also serve as the foundation for many investment products like index funds and exchange-traded funds (ETFs). In short, stock indices simplify market analysis and provide a reliable measure of how certain segments of the stock market are performing at any given time.

How Are Stock Market Indices Formed?

Indices are typically formed by selecting stocks that meet specific criteria such as:

• Industry sector (e.g., energy, banking, telecom)
• Market capitalization (the size of the company)
• Trading volume or liquidity
• Compliance with Shariah principles (in case of Islamic indices)

Once selected, the index value is calculated using one of several methodologies. The most commonly used in Pakistan is the free-float market capitalization method, where only the shares available for public trading are considered, excluding those held by insiders or government bodies.

Why Do We Need Stock Market Indices?

Stock indices serve several critical purposes:

• Benchmarking performance: Investors and fund managers use indices to compare the performance of their portfolios.
• Market sentiment: Indices provide a quick view of how the market is performing—whether bullish or bearish.
• Investment products: Mutual funds and Exchange Traded Funds (ETFs) often track specific indices.
• Economic indicators: Policymakers and economists analyze index trends to understand economic health.

Methods of Index Weighting

Not all indices are created equal. Depending on the weighting method, the influence of each stock on the index may vary.

1. Price-Weighted Index

In a price-weighted index, stocks are weighted based on their share price. This means that a higher-priced stock will have more influence on the index than a lower-priced one, regardless of the company’s size. Examples of global indices using this method include the Dow Jones Industrial Average (DJIA) and Nikkei 225.

However, price-weighted indices are rarely used in Pakistan, as they can be skewed by a few high-priced stocks.

2. Market Capitalization-Weighted Index

This is the most common method used in Pakistan. Here, the weight of each stock in the index is determined by its market capitalization—the total market value of a company’s outstanding shares.

Formula:
Market Capitalization = Share Price × Number of Outstanding Shares

The larger a company’s market cap, the more influence it has on the index. This method provides a more balanced view of the market’s true value.

3. Free-Float Market Cap

A more refined version of market capitalization weighting, free-float market capitalization excludes shares that are not available for public trading (like shares held by promoters or government). The KSE-100 Index uses this methodology.

Key Stock Indices in Pakistan

If you're wondering what are the 3 major stock indexes in Pakistan, they are the KSE-100 Index, KSE-30 Index, and the All Share Index—each offering unique insights into the market's performance.

• KSE-100 Index: The benchmark index of the Pakistan Stock Exchange (PSX), representing the top 100 companies by market capitalization.
• KSE-30 Index: Tracks the 30 most liquid stocks using free-float methodology, ideal for short-term trading strategies.
• All Share Index: Includes all listed companies on the PSX, providing a comprehensive view of the market.

These indices are essential tools for investors to analyze trends, assess market sentiment, and make informed trading decisions.

KSE-100 Index

The KSE-100 Index is the benchmark index of the Pakistan Stock Exchange (PSX). Introduced in 1991, it represents the top 100 companies in terms of market capitalization and sector representation. Covering over 85% of the market capitalization of the Exchange, the KSE-100 is a vital performance indicator for Pakistan's capital market.

AZEE Securities, through its daily research reports and market commentaries, provides regular updates and insights on the movement of this key index and the major contributors to its performance.

KSE-30 Index

Launched in 2006, the KSE-30 Index tracks the top 30 most liquid stocks listed on the PSX. It is based on free-float methodology and is ideal for short-term traders and institutional investors focusing on high-liquidity stocks.

ALL SHARE Index

The All Share Index includes all companies listed on the PSX. While it is broader in scope, it is not used as frequently for benchmarking due to the inclusion of many illiquid or less impactful stocks.

KMI-30 Index

The KMI-30 Index (Karachi Meezan Index) tracks the 30 most liquid Shariah-compliant stocks on the PSX. Introduced in 2008, this index was developed in collaboration with Meezan Bank’s Shariah Advisory Board, led by Justice (Retd.) Mufti Muhammad Taqi Usmani. It uses float-adjusted market capitalization with a 12% cap on individual securities, and it is rebalanced biannually.

This index is particularly relevant for Islamic investors seeking halal investment options in the stock market.

How Investors Use Indices

• Benchmark portfolios: Investors compare their returns against an index to measure performance.
• Track market trends: A rising index may indicate a bullish market, while a falling index could signal bearish sentiment.
• Create investment strategies: Many ETFs and mutual funds mirror index composition to offer passive investment options.
