The KSE-100 is Pakistan's most-watched financial number. It moves markets, drives headlines, and shapes the mood of millions of investors. But most people who follow it don't fully understand what it measures or how it's constructed.
Here's everything you need to know.
What is the KSE-100?
The KSE-100 (Karachi Stock Exchange 100 Index) is Pakistan's primary stock market benchmark. It tracks the share price performance of the 100 largest publicly listed companies on the Pakistan Stock Exchange (PSX). When you hear "the market was up 300 points today," that's the KSE-100.
It was launched in November 1991 with a base value of 1,000 points. By early 2026 it trades above 160,000 points — a 160x increase over 35 years.
How is the KSE-100 calculated?
The index is a free-float market capitalisation weighted index. This means:
- Each company's weight is proportional to its market value (share price × number of shares in free float)
- Larger companies have more influence on the index than smaller ones
- Only freely tradable shares are counted — government and strategic holdings are excluded from the calculation
When ENGRO's share price rises 2%, it moves the index more than when a small-cap company rises 2%, because ENGRO's market cap is larger.
The index is rebalanced periodically. Companies enter and exit based on market capitalisation.
Which sectors dominate the KSE-100?
The KSE-100 is heavily concentrated in a few sectors:
Banking: The largest weight in the index. MCB, HBL, UBL, Meezan Bank, and Bank Alfalah collectively represent 20–25% of the index.
Oil and gas: OGDC, PPL, POL, and the oil marketing companies (PSO, Shell) represent another significant chunk.
Fertilizer: FFC and ENGRO Fertilizers are index heavyweights with consistent dividend yields.
Cement: LUCK (Lucky Cement) is the largest, alongside DGKC, FCCL, and others.
Power: HUBC, KAPCO, and other independent power producers.
This concentration matters. When the banking sector or oil sector moves sharply, the entire index follows. Understanding sector dynamics is essential for understanding the KSE-100.
KSE-100 vs KSE-30 vs KMI-30
PSX maintains several indices:
KSE-30: Tracks the 30 most liquid stocks. Tends to be more volatile than KSE-100 since smaller constituents have more weight.
KMI-30: The Karachi Meezan Index — 30 most liquid Shariah-compliant stocks. Used as a benchmark for Islamic mutual funds.
ALLSHR: The All Shares Index, covering every listed company. The broadest measure of PSX performance.
For most purposes, the KSE-100 is the relevant benchmark.
How has the KSE-100 performed historically?
Over long periods, the KSE-100 has been one of the best-performing indices in Asia in local currency terms. Key milestones:
- 2002–2007: Dramatic bull run during Musharraf-era economic reforms
- 2008: Sharp crash during global financial crisis
- 2012–2017: Bull run to 50,000+ points
- 2018: Market correction on currency crisis and political uncertainty
- 2019–2020: Volatile period, COVID crash
- 2021–2023: Recovery and new highs
- 2024–2025: Renewed bull run on IMF programme, falling interest rates
The pattern repeats: macro stress causes sharp corrections, but quality businesses recover and compound over time.
What moves the KSE-100?
Interest rates: When the State Bank of Pakistan (SBP) raises rates, stocks typically fall — higher rates make fixed income more attractive and increase corporate borrowing costs. When rates fall, stocks typically rise.
Rupee stability: PKR weakness hurts import-dependent sectors (power, pharmaceuticals) and companies with dollar-denominated debt. It benefits exporters (textiles, technology).
Corporate earnings: Quarterly and annual results season drives individual stock movements and overall sentiment.
Politics and policy: Pakistan's political landscape creates recurring uncertainty. Markets tend to recover as political situations stabilise.
Global factors: Oil prices (affects cost of energy and the economy), global risk appetite, and IMF programme compliance all influence sentiment.

Common KSE-100 mistakes to avoid
Treating index movement as individual stock guidance. The index rising doesn't mean every stock is rising — and the index falling doesn't mean quality companies are becoming less valuable.
Over-trading around index swings. Short-term index moves are unpredictable. Most retail investors underperform by trading too frequently.
Ignoring valuation. At some index levels, the market is expensive. At others, it's cheap. Looking at the aggregate P/E of the KSE-100 gives context for whether current prices are historically reasonable.
